1 Quality Assurance

The high quality and reliability of integrated circuits from

Siemens are the result of carefully managed design and

production which is systematically checked and controlled at

each stage.

The procedures are subject to a quality assurance system;

full details are given in the brochure “Quality Assurance

lntegrated Circuits”.

Figure 1 and 2

show the most important stages of the QA

system. Quality assurance (QA) departments, independent

of production and development, are responsible for the

selected measures, acceptance procedures and information

feedback loops. Operating QA departments have state-of-

the-art test and measuring equipment at their disposal, work

according to approved methods of statistical quality control,

and are provided with facilities for accelerated life and

environmental tests used for both qualification and routine

monitoring tests.

The latest methods and equipment for preparation and

analysis are employed to achieve continuity of quality and

reliability.

2 Conformance

Each integrated circuit is subjected to a final test at the end of

the production process. These tests are carried out by

computer-controlled, automatic test systems as hundreds of

thousands of operating conditions as well as a large number

of static and dynamic parameters have to be considered.

Moreover, the test systems are extremely reliable and

reproducible. The quality assurance department carries out a

final check in the form of a lot-by-lot sampling inspection to

additionally ensure the minimum percent defectives to

ensure statistically that the PDA of released lots is less than

the AQL agreed. Sampling inspection is performed in

accordance with the inspection plans of DIN 40080, as well

as of the identical MIL-STD-105 or IEC 410.

3 Reliabilitiy

3.1 Measures taken during development

The reliability of ICs is already considerably influenced at the

development stage. Siemens has, therefore, fixed certain

design standards for the development of circuits and layout,

e.g. specifying minimum width and spacing of conductive

layers on a chip, dimensions and electrical parameters of

protective circuits for electrostatic charge, etc. An

examination with the aid of carefully arranged programs

operated on large-scale computers guarantees the

immediate identification and elimination of unintentional

violations of these design standards.

3.2 In-process control during production

The manufacturing of integrated circuits comprises several

hundred production steps. As each step is to be executed

with utmost accuracy, the in-process control is of outstanding

importance. Some processes require more than a hundred

different test measurements. The tests have been arranged

such that the individual process steps can be reproduced

continuously.

The decreasing failure rates reflect the never ending effort in

this direction; in the course of the years they have been

reduced considerably despite an immense increase in IC

complexity.

3.3 Reliability monitoring

The general course of IC failure rate versus time is shown by

a so-called “bathtub” curve.The failure rate has its peak

during the first few operating hours (early failure period). After

the early failure period has ended, the “constant” failure rate

period starts during which the failures may occur at an

approximately uniform rate. This period ends with a repeated

rise of the curve during the wear-out failure period. For ICs,

however, the latter period usually lies far beyond the service

life specified for the individual equipment. Reliability tests for

ICs are usually destructive examinations. They are,

therefore, carried out with samples. Most failure mechanisms

can be accelerated by means of higher temperatures. Due to

the temperature dependence of the failure mechanisms, it is

possible to simulate future operational behavior within a short

time by applying high temperatures; this is called life test. The

acceleration factor

for the life test can be obtained from

Arrhenius’s equation

where

is the temperature at which the life test is

performed,

is the assumed operating temperature and

is Boltzmann’s constant.

Important for factor

is the activation energy

. It lies

between 0.3 and 1.3 eV and differs considerably for

individual failure mechanisms.

For all Siemens ICs the reliability data from life tests is

converted to an operating temperature of

= 55

assuming an average activation energy of 0.5 eV. The

acceleration factor for life tests at 125

C is thus 22,

compared with operational behavior. This method considers

also failure mechanisms with low activation energy, i.e. which

are only slightly accelerated by the temperature effect.

Various reliability tests are periodically performed with IC

types that are representative of a certain production line this

is described in the brochure “Quality Assurance Integrated

Circuits”. Such tests are e.g. humidity test at 85

C and 85 %

relative humidity, pressure cooker test, as well as life tests up

to 1000 hours and more. Test results are available in the form

of summary reports.

PMB 2905-F P-TQFP-64-1 (SMD)

GSM Analog Interfacing Module (GAIM) PMB 2905

Siemens Aktiengesellschaft 21

General Description

The PMB 2240, 2245, 2247 family are single-chip

transmitters which include a prescaler for the RF-oscillator

signal and a fixed PLL for the IF-oscillator signal. The

transmitter family is designed for use in combination with the

single-chip receiver family PMB 2405, 2407 and the PLL

PMB 2307 for mobile telephones according to the GSM, PCN

and PCS standards and other vector modulated digital

systems. It is fabricated using Siemens B6HF silicon

process:

The PMB 2240/45/47 transmitters include the active

structures for the main oscillator circuit. Alternatively the

oscillator signal can be supplied from an external source. The

oscillator signal is buffered for off-chip use.

There is a prescaler by 64/65 for the RF-oscillator signal on

chip, which can be used to implement the PMB 2307 PLL

circuit.

The on-chip FIX-PLL consists of the system clock divider, the

IF-oscillator signal divider, the phase detector and the charge

pump. The IF-oscillator signal divider is driven by the

oscillator on the PMB 2405/07 or by an external discrete

VCO. The IF-oscillator signal divider ratio of PMB 2240 and

PMB 2245 is fixed. It can be selected either divided by 1 or by

3 using PMB 2247 and PMB 2407 to drive the FIX-PLL with

two IF frequencies (450 MHz or 150 MHz) to avoid spurious

problems for PCS application.

The two oscillator signals (IF and RF) are combined in the

transmit mixer, and the image sideband and other mixing

products are to be suppressed by an external interstage filter.

The filtered signal reenters the chip at the modulator inputs.

The modulator generates two orthogonal carriers which are

mixed with the I- and Q modulation signals by two multipliers.

The phase between the two carriers can be fine-adjusted to

90° (orthogonality) by two external resistors for maximum

SSB suppression. The outputs of the multipliers are added

and amplified by a linear output stage.

General Description

The PMB 2405, 2407 family are single-chip double-

conversion heterodyne receivers with LO-phase shifting

circuitry for the I/Q-phase demodulation on chip. It also

includes a switchable low noise amplifier, the second local

oscillator with a VCO output buffer, a programmable gain

controlled IF amplifier, two differential operational amplifiers

for base band signal filtering and a power-down circuitry.

The receiver family is designed for use in combination with

the single chip transmitter family PMB 2240, 2245, 2247 and

the PLL PMB 2307 for mobile telephones according to the

GSM, PCN and PCS standards and other vector modulated

digital systems. It is fabricated using Siemens B6HF silicon

process.

The input signal is amplified by the internal LNA and filtered

by an external filter. The filtered signal and the first local

oscillator signal LO1 are mixed down to an intermediate

frequency (IF). The amplification of the IF signal is performed

by a digitally programmable gain-controlled amplifier.

The second local oscillator signal LO2 is generated either by

an on-chip oscillator or by an external VCO. The internal LO2

signal is fed to a divider (PMB 2405-by 1; 2407-by 1 or 3) and

then to a buffered output and also to a divider, which

generates orthogonal signals at half the VCO frequency. The

filtered IF signal re-enters the chip at the IF input, where it is

amplified and converted to the final output frequency with

each of the orthogonal signals. The resulting in-phase and in-

quadrature signals pass through differential output drivers.

Two differential operational amplifiers can be used as active

baseband filters. At both outputs the differential offset is

sensed via the sample and hold circuitry. A feedback loop

corrects the remaining offset error below the tolerable input

value of the GAIM PMB 2905 or any other baseband A/D

converter.

Applications

• Vector modulated cellular and cordless systems:

PMB 2405: GSM, PDC, DAMPS,

PMB 2407: PCN, PCS (DCS1900), WLAN etc.

1.25-GHz Dual PLL with Prescaler

2.5-GHz Dual PLL with Prescaler

General Description

The PMB 2302, PMB 2303 are single chip dual Phase

Locked Loop (PLL) synthesizers with programmable

frequency dividers for use in mobile communication

equipment. It is fabricated using Siemens B6HF silicon

bipolar process.

The circuit consists of high speed dual modulus dividers, shift

registers, programmable counters (2 A-, 2 N- and

2 R-counters), phase detectors with charge pump and a

control logic block.

Since one of the high speed dual modulus dividers is able to

handle frequencies of up to 1.25 GHz (2.5 GHz), there is no

need to add a dedicated external prescaler. The second dual

modulus divider handles frequencies up to 500 MHz. The

switching signals for the dividing ratios are generated by the

corresponding A-counters.

The A-counter and the N-down-counter are programmable

via the 3-wire bus. They are clocked by the dual modulus

divider output signals. The carry outputs of the N-counters

are connected to the frequency inputs of the corresponding

phase detectors and are controlling the loading of the

programmed A-/N-counter start values.

The two 11 bit R-counters are also programmable and are

serving as reference frequency dividers. Their carry outputs

are connected to the corresponding reference frequency

inputs of the phase detector and are controlling the loading of

the programmed counter start values.

The phase detectors are of PFD-type (phase and frequency

sensitive). They have a linear output characteristic in the 0˚

phase error region.

The control logic handles phase detectors output polarity,

charge pump output currents and software-generated

power-on (all circuit parts except the shift registers and data

latches).

Applications

and IF synthesizers

Features

PLL Frequency Synthesizer PMB 2306

PMB 2307

General Description

The PMB 2306, PMB 2307 PLL are high speed CMOS ICs

are especially designed for use in battery-powered radio

equipment and mobile telephones. The intended application

will be in GSM, PCN, DECT and other digital mobile systems.

The wide range of dividing ratios also allows application in

analog systems.

The circuit consists of a reference-, A- and N-counter, a

dual-modulus-control logic, a phase detector with charge

pump and a serial control logic. The setting of the operating

mode and the selection of the counter ratios is done serially

at the ports CLK, DA and EN.

The operating modes allow the selection of single or dual

operation, asynchronous or synchronous data acquisition,

4 different antibacklash-impulse times, 8 different PD-output

current modes, polarity setting of the PD-output signal,

adjustment of the trigger-edge of the MOD-output signal,

2 standby modes and the control of the multifunction outputs

MFO1 and MFO2.

The reference frequency is applied at the Rl input and scaled

down by the R-counter. Its maximum value is 50 MHz. The

VCO frequency is applied at the Fl input and scaled down by

the N- or N/A-counter according to single or dual-mode

operation. The maximum value at Fl is 220 MHz at single-,

and 65 MHz at dual-mode operation.

The phase detector is frequency and phase sensitive. It

produces a phase detector signal with adjustable anti-

backlash impulses in order to prevent a dead zone at very

small phase deviations. Phase differences smaller than

100 ps can therefore be resolved.

Programming of the IC is done by a serial data control. The

contents of the messages are assigned to the functional units

according to the destination address. Single or dual-mode

operation as well as asynchronous or synchronous data

acquisition is set by status 2 and should therefore precede

the programming of the counters.

The PMB 2306/PMB 2307 offer the possibility of

synchronous data acquisition to avoid error signals at the

phase detector due to non-corresponding dividing factors in

the counters produced by asynchronous loading.

Synchronous programming guarantees control during

changes of frequency or channel. That means that the state

of the phase detector or the phase difference is kept

maintained, and in case of “lock in”, the control process starts

with the phase difference “zero”.

Synchronous transmission is particularly advantageous

when large transfers in channel are to be made in a specific

short transient recovery time. For this purpose a larger

reference frequency is switched to in order to achieve rapid-

“rough”-transient response, increasing the bandwidth of the

loop at the time. When reaching the “quasi lock-in” state, the

reference frequency is switched back to its original values.

Adjustment to the “actual” value then takes place with the

usual transient response as for small transfers in channel.

The synchronous transmission ensures that no additional

phase errors arise due to the change of reference

frequencies.

The PMB 2306/2307 has two standby modes (standby1, 2)

to reduce the current consumption.

• Standby1 switches off the whole circuit, the current

consumption is reduced to below 1 µA.

• Standby2 switches off the counters, the charge pump and

the outputs, only the preamplifiers stay active.

The standby modes do not affect the port output signal. For

the influence on the other output signals see standby table.

detector

B6HF

General Description

The PMB 2308, PMB 2309 are Phase Locked Loop (PLL)

synthesizers with programmable frequency dividers for use

in mobile communication equipment. It is fabricated using

Siemens B6HF silicon bipolar process.

The circuit consists of high speed dual modulus divider, shift

phase detector with charge pump and a control logic block.

Since the high speed dual modulus divider is able to handle

frequencies of up to 1.25 (2.5) GHz, there is no need to add

a dedicated external prescaler. The switching signals for the

dividing ratio 16/17 (32/33) is generated by the A-counter.

The A-counter and the N-down-counter are programmable

via the 3-wire bus. They are clocked by the dual modulus

divider output signal. The carry output of the N-counter is

connected to the frequency input of the phase detector and

is controlling the loading of the programmed A-/N-counter

start values.

The 11 bit R-counter is also programmable and is serving as

reference frequency divider. Its carry output is connected to

the reference frequency input of the phase detector and is

controlling the loading of the programmed counter start

value.

The phase detector is of PFD-type (phase and frequency

sensitive). It has a linear output characteristic in the 0˚ phase

error region.

The control logic handles phase detector output polarity,

charge pump output current and software-generated power-

down (all circuit parts except the shift registers and data

latches).

Applications

All mobile communication analog and digital systems as RF-

and IF synthesizers

Overview on ICs for Digital Terminals

ISDN Voice Terminals

With the digitization of the local loops, new ICs are needed to

adapt the voice and data sources.

Because of the analog/digital conversion is implemented in

the telephone, Digital Signal Processing techniques (DSP)

are suitably powerful tools for accomplishing this task. The

ARCOFI® PSB 2160, ARCOFI®-BA PSB 2161 and

ARCOFI®-SP PSB 2165 or PSB 2163 make the best use of

this technology to deliver programmable, telephone specific

codec/filter.

The modular concept allows the support of several interfaces

like UP0 (ISAC®-P), UPN (ISAC®-P TE, SmartLink-P), S0

(ISAC®-S, ISAC®-S TE) and Uk0 (IEC-Q, IEC-T). All interface

controllers including layer-1, -2 support the IOM-2 Bus and

are software compatible.

The adaptation of existing data terminals (DTE) to an ISDN

through a variety of interfaces (X.21, V24, RS232C, …) is a

subject being covered by a number of emerging standards.

The ITAC ISDN adapter circuit PSB 2110 brings a flexible

solution to each configuration.

A typical subscriber terminal configuration is shown in the

ISDN Data Access

Shorter dial-up times, higher data rates and simultaneous

voice/data transmission comparing to analog transfer via

modem make ISDN very interesting for data access.

Especially ISDN data transfer via PC card is becoming more

and more popular.

The signs below show 2 solutions of passive PC cards.

The passive low cost version (figure 2) is optimal for

point-to-point data transfer. The modular concept for this

version includes the HDLC controllers and the interface

controllers (optional for UP0-, UPN-, S0-, Uk0-interfaces

→ see ISDN Voice Terminals). The serial controllers HSCX

(8-bit interface) and ESCC2 (16-bit interface) can be used in

many applications in telecom and datacom systems by

offering dual channel HDLC controlling and DMA capability.

The shown enhanced passive PC-card version (figure 3)

includes the interface controllers and a DSP-based solution.

There is a dedicated ROM-coded DSP-version for supporting

modem (V.32), fax (V.29), data adaption (V.110, USART

framing) and HDLC controlling in development. Please

contact the Siemens sales office for details.

Like the ISDN Voice Terminals (figure 1) both PC-card

version are expendible for voice and active PC-card

solutions.

General Exchange Architecture

Analog Line Cards

In a digital exchange system the subscriber line boards

provide the link between the subscriber and the switching

network. The basic functions of analog line boards are

known under acronym BORSHT (Battery, Overvoltage,

Ringing, Supervision, Hybrid, Testing). Additional important

tasks are voice frequency band limitation, analog to digital

conversion into time discrete digital equivalents, time-slot

assignment on the PCM highways and handling of

signaling and control information.

The conventional implementation uses two PCM ports

and one µP interface per subscriber line leading to a large

amount of wiring and, thus, problems are as crosstalk and

large board size.

The conventional implementation is also characterized by

the fixed adjustment of line interface conditions although

telephone line conditions vary considerably with national

standards and even with subscriber line installations. Under

adverse conditions telecommunication equipment must

match the subscriber line and termination impedances while

suppressing return echoes in the two to-four-wire hybrid

network. Compensating for line attenuation is just as critical

for balancing the voice signals in the transmission and

reception paths. To improve voice quality, subscriber line

boards have to be matched to different line conditions by

means of interchangeable discrete components. This

approach is very costly regarding line board design and

manufacturing. Furthermore, the reliability of a board filled

with parts, wires and connections will decrease rapidly.

The best solution to eliminate these line card trouble spots is

the design of one standard line card, which can be

customized for various line conditions and postal

specifications through software control. The right choice of

dedicate device allows the optimal line card design for each

application in public switches, PBX systems as well as in all

kinds of multiplexers and concentrators.

Optimized Line Board Architecture

The Siemens Semiconductor concept is characterized by a

centralized PCM interface controller device providing the

variable Time-Slot Assignment (TSA), the communication

with up to 64 subscriber line devices such as a signal

processing codec/filter (SICOFI) or ISDN devices via the SLD

(Subscriber Line Data) or IOM-2 (ISDN Oriented Modular)

interface, and the interface with a microprocessor.

As a characteristic architectural feature, for test, monitoring,

and control purposes, the device permits efficient switching

of data streams between all these interfaces and, therefore,

ensures transparency between the PCM channels and

control or signaling data. This opens up attractive

possibilities such as common-channel signaling and

microprocessor access to PCM data.

The use of the signal processing codec/filter (SICOFI) avoids

the analog network which has to be matched to different

requirements by interchanging its discrete components.

Based on Digital Signal Processing (DSP) methods the

SICOFI allows the complete control of the line conditions by

software.

The all-over flexibility and programmability of the unique

device concept gives the user the capability for designing a

standard line card which can be optimized for each

application and can be matched to various line conditions.

The SLD/IOM-2 architecture leads to a highly modular line

board configuration with low wiring, reduced board area, and,

dependent on the SLIC being used, very few external

discrete components.

Siemens ICs for Analog Subscriber Lines, Configurations and Interfaces

Siemens Aktiengesellschaft 86

SLD/IOM

-2 Interface

The SLD-bus is used by the PIC (PCM Interface Controller)

to interface with the subscriber line devices. A Serial

Interface Port (SlP) is used for the transfer of all digital voice

and data, feature control and signaling information

between the individual subscriber line devices, the PCM

highways and the control backplane. The SLD approach

provides a common interface for analog or digital per-line

components. Through the PIC, which is the key device in

the SLD-architecture, the PCM data is transparently

switched onto the PCM highways. The PBC (Peripheral

Board Controller) will make analog and digital subscriber line

boards plug-compatible in a line equipment rack.

There are three wires connecting each subscriber line device

and the PIC: two common clock signals shared among all

devices, and a unique bidirectional data link for each of the

eight SIP lines. The Direction signal (DIR) is an 8-kHz clock

output from the PIC (master) that serves as a frame sync to

the subscriber line devices (slave) as well as a transfer

indicator. The data are transferred at a 512-kHz rate, clocked

by the Subscriber Clock (SCLK). When DIR is high (first half

of the SLD 125 µs frame), four bytes of digital data are

transmitted on the SLD-bus from the PIC to the slave (receive

direction). During the second half of the frame when DIR is

low, four bytes of data are transferred from the slave back to

the PIC (transmit direction).

Channel A and B are 64-kbit/s channels reserved for voice or

data to be routed to and from the PCM highways. In an

application where one SICOFI is connected to a SIP, voice is

received on channel A and transmitted on channel A and B.

For a three-party conference, channel B is the third-party

voice channel. If two SlCOFls are connected to one SIP,

channel A is assigned to one and channel B to the other

SICOFI. Conferencing is not possible in this configuration.

With digital subscriber line devices the two bytes can be used

to carry 64-kbit/s data channels. The third and sixth byte

locations are used to transmit and receive control information

for programming the slave devices. The last byte in each

direction is reserved for signaling data.

Siemens Aktiengesellschaft 87

SLD/IOM

-2 Interface

The lOM®-Revision-2 (IOM®-2) standard defines an industry

standard serial bus for interconnecting telecommunication

ICs. The standard covers line card, NT1, and terminal

architectures for ISDN and analog loop applications.

The line-card mode of IOM-2 provides a connection path

between line transceivers (ISDN) and codecs (analog), and

the line-card controller; the line card controller provides the

connection to the switch backbone. The IOM-2 bus time

multiplexes data, control, and status information for up to

eight ISDN transceivers or up to 16 codec/filters over a single

full-duplex interface.

By providing data, control, and status information over a

serial channel, the IOM-2 bus eliminates the need to have a

microprocessor interface on the transceiver or codec. This

reduces pin count and simplifies line-card layout, thus

reducing cost.

Information is multiplexed into frames, which are transmitted

at an 8-kHz rate. The frames are subdivided into from one to

eight subframes, with one subframe being dedicated to each

transceiver or pair of codecs. The subframes provide

channels for data, programming, and status information for a

single transceiver or a codec pair.

Extended Line Card Controller (ELIC

)

General Description

The Extended Line Card Controller (ELIC) PEB 20550-H is a

device to allow the control, supervision and processing of

voice, data and signaling information. It also provides access

for the microcontroller to write/read data to/from the IOM and

PCM interfaces and gives control over layer-1 devices.

Revolutionary is the multiplexing concept allowing to use only

one implemented HDLC controller to process the signaling

information for up to 32 digital subscribers.

The switching part of the ELIC controls space and times

switching functions between subscriber line devices and time

division multiplex highways. Furthermore it controls the flow

of information between the subscriber interface ports and a

processor.

For processing signaling information two different HDLC

controllers are implemented. The SACCO A is a Serial

Access Communication Controller (HDLC) which allows

extracting D-Channel information transported on the IOM

interface. The data is then passed to the microcontroller. ln

the downstream direction, the SACCO A passes data,

packed in the HDLC protocol, from the microcontroller to the

IOM interface.

With 4 IOM interfaces, and 8 digital subscribers possible per

interface, former designs needed 32 HDLC controllers (one

for the D-channel of every subscriber). The SACCO A of the

ELIC can serve all 32 channels in a time-multiplexing

manner. This process is controlled by the BUS ARBITER.

This part of the ELIC monitors all D-channels of the IOM

interface and locks the SACCO A onto one D-channel as

soon as the start of a HDLC frame is detected. After the end-

flag of the HDLC frame has been received, the SACCO A is

released again and can lock onto the next D-channel as soon

as a new request is detected. During the assignment of the

HDLC controller to a certain channel the other subscribers

are not allowed to send information on their D-channels. To

assure this a blocking mechanism is implemented which

indicates to corresponding terminals that they may not use

the D-channel. This mechanism works as well for the

standard ISDN S0 as for the proprietary UP interface, a two

wire ISDN capable interface for PBXs. Any ISDN Telephone

can be connected to a PBX because the standard arbitration

mechanism is used for blocking the phones.

This concept saves the space and the costs of up to

32 HDLC controllers. Due to the bursty characteristic of the

signaling data, one HDLC controller is sufficient to process

this data flow. For central office applications the ELIC is not

recommended when the arbiter is used, as PTTs require

transparent D-channels. In this case the SACCO A can be

used as an independent HDLC controller.

If the design needs higher D-channel data rates additional

HDLC controllers (IDEC, PEB 2075) can be connected. This

can either be done on the IOM interface and is than fixed for

a certain subscriber or via the PCM interface which makes

this extra HDLC controller flexibly assignable.

The SACCO B is a second integrated HDLC controller

behaving like an external device. It is mainly intended for

signaling information between the line card and the group

processor on the main board. This can be done either via a

dedicated signaling highway or via the PCM highway. The

SACCO B can also be used for music on hold, conferencing

access and other features. The HDLC information handling

between SACCO A and SACCO B always has to go via a

microprocessor.

IOM-1, SLD or PCM

Signal Processing Codec Filter (SICOFI

)

General Description

The Signal Processing Codec Filter (SICOFI) PEB 2060 is a

fully integrated PCM codec (coder-decoder) and transmit/

receive filter produced in advanced CMOS technology for

applications in digital exchange telecommunication systems.

Based on a digital filter concept the PEB 2060 provides

improved transmission performance and high flexibility. It

enables the control of the device’s analog behavior by digital

signal processing, including attractive features such as

programmable trans-hybrid balancing, impedance matching,

level control and frequency response correction. The device

is optimized for working in conjunction with the PCM Interface

Controller PEB 2052/55.

The analog input signal is A/D converted, digitally filtered and

transmitted either PCM-encoded or linear. Antialiasing is

done with a 2nd order Sallen-Key Prefilter (PREFI). The A/D

Converter (ADC) is a modified slope adaptive interpolative

coder with a sampling rate of 128 kHz. Digital downsampling

to 8 kHz is done by subsequent decimation filters D1 and D2

together with the PCM bandpass filter (BP).

The digital input signal is received PCM encoded or linear,

digitally filtered and D/A converted to generate the analog

output signal. Digital interpolation up to 128 kHz is done by

the PCM lowpass filter (LP) and the interpolation filters l1 and

l2. The D/A Converter (DAC) output is fed to the 2nd order

Sallen-Key Postfilter (POFI).

The high flexibility of the SICOFI is based on a variety of user

programmable filter, which are analog gain adjustment AGR

and AGX, digital gain adjustment GR and GX, frequency

response adjustment R and X, impedance matching filter Z

and the trans-hybrid balancing filter B.

The SICOFI bridges the gap between analog and digital

voice signal transmission in modern telecommunication

systems.

High performance oversampling Analog-to-Digital Converter

(ADC) and Digital-to-Analog Converter (DAC) provide the

conversion accuracy required. An analog antialiasing

Prefilter (PREFI) and smoothing Postfilter (POFI) is included.

The dedicated on-chip Digital Signal Processor (DSP)

handles all the algorithms necessary, e.g. PCM bandpass

filtering, sample rate conversion and PCM comparing. The

3-pin serial SLD-Bus interface handles digital voice

transmission and SICOFI feature control. Specific filter

programming is done by downloading coefficients to the

Coefficient RAM (CRAM).

The 10-pin parallel signaling interface provides for a powerful

per line SLIC control.

Dual Channel Codec Filter (SICOFI

-2)

General Description

The Dual Channel Codec Filter PEB 2260 (SICOFI-2) is a

fully integrated PCM codec and filter fabricated in low power

CMOS technology for applications in digital communication

systems. Based on an advanced digital filter concept, the

PEB 2260 provides excellent transmission performance and

high flexibility. The digital signal processing approach

includes attractive programmable features such as

trans-hybrid balancing, impedance matching, gain and

frequency response correction.

The SICOFI-2 can be programmed to communicate either

with SLD or with IOM-2 compatible PCM-interface controllers

(e.g. PEB 2052/54/55).

The device bridges the gap between analog and digital voice

signal transmission in modern telecommunication systems.

A high performance oversampling Analog-to-Digital

Converter (ADC) and Digital-to-Analog Converter (DAC)

provide the conversion accuracy required. Analog

antialiasing Prefilters (PREFI) and smoothing Postfilters

(POFI) are included. The dedicated on-chip Digital Signal

Processor (DSP) handles all the algorithms necessary, e.g.

PCM bandpass filtering, sample rate conversion and PCM

companding. The SLD/lOM-2 interface handles digital voice

transmission, SICOFI-2 feature control and access to the

SICOFI-2 signaling pins. Specific filter programming is done

by downloading coefficients to the Coefficient RAM (CRAM).

Signal Processing Codec Filter (SICOFI

-4)

General Description

The Signal Processing Codec Filter (PEB 2465-H), SICOFI-4

is the interface between four analog subscribers and the

digital switch. The chip combines all the circuitry needed for

encoding, decoding and PCM filtering of 4 speech channels

on CMOS chip. An integrated digital signal processor (DSP)

allows the analog line card to be adapted to the widest variety

of national specifications and applications by programming

the individual digital filter functions. A wide variety of SLlCs

(subscriber line interface circuits) can be employed and

simply adapted.

The SICOFI-4 can be used in both, PBXs and public

switches. The external configuration does not vary – only

decoupling capacitors are needed. Widely differing national

specifications can be met with a single hardware by just

changing the filter coefficients: Signal level, terminating

impedance, equivalent impedance, frequency response

correction and the required coding procedure (A- or µ-Law)

are simple to program. Siemens provides well proven

software for calculating the required coefficients.

The SICOFI-4, together with standard SLlCs, also fulfills the

new specification for idle channel noise in the out-of band

range, already demanded by Japan and Great Britain.

A flexible test concept operating at component level as well

as at system level is provided to support users in designing

and manufacturing their systems. The following test options

are integrated into the SICOFI-4:

• BIST (built-in self test) in the digital part

• Boundary scan as per IEEE 1149.1

• Functional testing with various test loops

• Simple stimulation by two built-in DTMF (Dual Tone

Multifrequency) tone generators

• Function self test using what is known as the “level

metering function” with which not only the chip but also the

SLIC connected to it can be tested (system test).

The powerful, modular IOM-2 interface implemented

on the allows minimal wiring to be used on the board and

thereby a low-cost design. A suitable controller (e.g. the

ELIC, PEB 20550-H) is used to direct the relevant

coefficients for filter programming and the required control

signals as well as the voice signals to the SICOFI-4. Signals

from the SLIC can be issued by the SICOFI-4 to the IOM-2

interface and read out under interrupt control. This

significantly reduces the load on the microcontroller.

Features

• Codec for four analog subscribers (public switch and

PBX) usable towards the trunk and the subscriber

• Specification according to relevant CCITT, EIA and

LSSGR

PEB 3065 (SLICOFI®) General Description

The Signal Processing Subscriber Line Interface Codec Filter

SLICOFI is a logic continuation of the well established family

of the Siemens DSP Codec-Filter ICs with the vertical

integration of all DC-feeding, supervision and PL meterpulse

injection features on-chip as well. Fabricated in a standard

1 µm BiCMOS technology the SLICOFI is tailored for very

flexible solutions in digital communication systems. For the

first time the SLICOFI uses the benefits of a DSP not only for

the voice channel but even for line feeding and supervision

which leads to a very high flexibility without the need for

external components.

Based on an advanced digital filter concept, the PEB 3065

provides excellent transmission performance. The new filter

concept leads to a maximum of independence between the

different filter blocks. Each filter block can be seen as a one

to one representative of the corresponding network element.

Together with the software package SLICOS, filter optimizing

to different applications can be done in a clear and straight

forward procedure. The AC frequency behaviour is mainly

determined by the digital filters. Using the new oversampling

1-bit Σ∆-AD/DA converter, linearity is only limited by second

order parasitic effects.

The new – digital – solution of line feeding offers free

programmability of feeding current and voltage as well as

very fast settling of the DC operating point after transitions. A

0.4-Hz lowpass filter in the DC loop is mainly responsible for

the system stability.

Additionally telefax generation and filtering is implemented

as well as free programmable (balanced) ring generation with

zero crossing injection. Offhook detection with

programmable thresholds is possible in all operating modes.

To reduce overall power consumption of the line card, the

SLICOFI provides a special mode called Power Denial where

offhook is done via two high voltage inputs (VLINE) directly

connected to the line since the HV-SLIC is switched off.

PEB 3065 (SLICOFI®) Features

ISDN High Voltage Power Controller (IHPC)

General Description

The IHPC is an integrated power controller especially

designed for feeding two-wire ISDN-transmission lines. One

line can be powered by one IHPC. An external resistor

defines the value of the current-limit for the line. Powering

can be switched on or off by the logic inputs “PFEN” and

“PFENQ”. With a logic low at the “APFI” output the IHPC

signals that current-limiting is active; this signal is low-pass

filtered. An external capacitor defines the corner frequency of

this low-pass filter and the resulting delay time respectively. A

second external capacitor is needed to make sure that

longitudinal disturbance (AC) will not produce a current

limiting effect. Line current-limiting and reducing this limiting

level in case of overtemperature guards the IHPC against

overloads.

Features

• Battery voltage up to 130 V

• Supplies power for one transmission line

• Current limiting and chip temperature control

• Limiting current can be programmed by an external

resistor

• Automatically reduced feeding current in case of

overtemperature

• Reliable 170 V Smart Power Technology (SPT 170)

• Small P-DSO-20 package

ISDN Layer-2 Protocol Controllers

ISDN Communications Controller (ICC)

General Description

While the IOM structure supports high flexibility with respect

to layer-1 of data transmission, the ISDN communications

controller can be used in all applications for link access

protocol control. This is of great importance regarding

production volume, software continuity and engineering effort

necessary for the use of the complex circuit. For further

reduction of software, high-level layer-2 support has been a

main target of circuit definition.

D-channel protocol handling is the main task of the ICC. Its

characteristic features are determined by an on-chip LAPD

controller and a sophisticated FlFO-structure. The LAPD

controller performs multiframe operation largely

autonomously with a window size of 1. All S- and l-frames,

including the address and control fields, are evaluated in the

ICC. Depending on the status of the controller, positive or

negative acknowledgements are generated without

interrupting the CPU. When the procedure is terminated, an

interrupt status is generated to inform the CPU of the status

of the procedure. To enable the ICC device to be used in

complex protocol applications with window size of up to 7, a

transparent mode is implemented. In this mode the layer-2

headers are transferred transparently to the CPU.

The synchronization of the 16-kbit/s D-channel with the CPU-

bus is performed by buffers with a capacity of 64 bytes per

direction. Sophisticated buffer controllers allow overlapping

input/output operation, which ensures that the maximum

packet length is not limited by the buffer size.

This feature greatly reduces the dynamic load of the

microprocessor system.

Features

• High-level support of LAPD-protocol

• FlFO-buffer (64 bytes per direction) for efficient transfer of

D-channel messages

• IOM interface compatible (IOM-1 or IOM-2)

• Standard parallel microprocessor interface

• Support of activation/deactivation procedure

• Variety of operating modes

•µP access to B-channels and IOM-intercommunication

channels

• Control of peripheral devices via IOM Monitor and C/l-

channel protocols

•2-µm CMOS technology and low power consumption:

Standby: 2 mW

Active: 4 mW at 512 kHz

ISDN D-Channel Exchange Controller (IDEC

)

General Description

With the IOM-2 interface, designers have more flexibility with

respect to handling of D-channel information. Layer-1

transceivers are connected over the IOM-2 interface directly

to either the PEB 2055 (EPIC-1) or the PEB 2054 (EPIC-S).

These devices are capable of switching not only the

B-channels but also the D-channel. Thus, the designer can

decide whether he wants to process D-channel signaling

information decentralized, on the line card, or pass it through

to be processed centrally.

The IDEC has been optimized for processing the D-channel

signaling information on digital exchange line cards. Four

independent HDLC controllers have been implemented on a

single IC. Thus, one IDEC can handle the D-channels of up to

four subscriber lines.

The IDEC is based on the same core architecture as the

PEB 2070 ICC, but has been optimized for exchange line

cards and then repeated four times.

Features

• Four independent HDLC channels

• 64-byte FIFO buffering per channel and direction

• Handling of basic HDLC functions

• Single or quad connection to serial transmission lines

• IOM- or PCM interfaces

• Programmable time-slots and channel data rates (up to

4 Mbit/s)

• Collision detection and resolution circuitry for shared

time-slots

• 8-bit parallel µP interface with vector interrupt

• Advanced low power CMOS technology: 50 mW

ISDN Layer-1 Transceivers

S-Bus Interface Circuit (SBC)

General Description

The four-wire S-interface between subscriber terminals and

network termination has been standardized by CCITT

recommendation I.430. Making use of a passive bus which

provides separate receiver and transmit loops operating at

192-kbit/s, up to eight terminals can be connected to the

network termination. In case more than one terminal want to

access the bus at the same time, a procedure is provided for

resolving the collision problem. Since all layer-1 functions

such as frame structure, data rate, power feeding,

transceiver characteristics, activation/deactivation and

subscriber access procedure are well defined, the S-bus can

be considered an important tool for standardization of data

communication equipment. It supports connections with a

maximum length of 1 km in a point to-point and 150 m in a

point-to-multipoint bus configuration.

The SBC is designed to meet all CClTT requirements, and,

moreover, implements additional features necessary in

specific applications. The device contains the transceiver

function, timing recovery for the different modes of operation,

circuitry for the collision resolution function and a state

control block to handle the activation/deactivation

procedures autonomously without the support of a

microprocessor. A flexible buffer structure performs the

frame-alignment function in PBX-trunk applications, where

the system clock deviates from the central office clock

derived from the line. Matching of the actual line attenuation

is supported by receiver circuitry which contains adaptively

adjustable thresholds.

Not for new development.

For new development use the SBCX (PEB 2081)

Features

• S-bus transceiver according to CCITT I.430

• Recovery of clock and frame signals in different modes of

application.

• Frame alignment for trunk module application

• IOM interface compatible (IOM-1)

• Handling of command/indication information during the

activation/deactivation procedure

• Switching of test loops

• Control of bus access by echo-bit handling

• Wake-up unit for activation from power-down state

ISDN Echo-Cancellation Circuit (IEC-T)

General Description

The most challenging requirement in ISDN is full-duplex

transmission at a data rate of 144 kbit/s over the existing

twisted-pair telephone cables (U-interface). Among several

approaches for solving this problem, ping-pong time-

compression multiplexing and echo cancellation have been

proposed as most suitable for VLSI implementation.

Moreover, echo cancellation has proven to be the best

method for public lines which typically reach lengths in the

range of 8 km.

After a careful study of different transmission codes, a 4B3T

block code was chosen for the IEC-T which make use of

ternary coding of the binary information. A particular

advantage of this code is its low frequency, DC-free

performance spectrum with its energy peak at about 40 kHz.

In this context, for a bit rate of 160 kbit/s the required baud

rate is as low as 120 kHz. As a result transmission systems

benefit from, low line attenuation low crosstalk distortion and

high possible signal levels without causing EMI-problems.

The IEC-T is offered as a two chip solution consisting of:

• Digital part, called PEB 20901

• Analog part, called PEB 20902

Features

• Full-duplex two-wire U-transceiver

• 144-kbit/s user bit rate (2B+D)

• 160-kbit/s total bit rate including maintenance and

synchronization

• Low transmission frequency of 120 kbaud by using the

4B3T-ternary block code

• Adaptive echo cancellation and equalization using digital

filtering (DSP)

• Recovery of clock and frame signals from the data stream

• IOM-1 interface compatible

• Transmission range up to 8 km with 0.6-mm wires

• Handling of command/indication information during

activation/deactivation procedure

• Switching of test loops

• Wake-up unit for activation from power-down state

• Several operating modes including trunk applications with

frame alignment

•2-µm CMOS technology for PEB 20902, 1-µ technology for

PEB 20901

• 320-mW power consumption

• Repeater mode with no external devices

ISDN Burst Transceiver Circuit (IBC)

General Description

In addition to four-wire S-interface terminals, the IOM

architecture also supports two-wire terminals for PBX

applications. A survey of PBX-loop conditions demonstrates

that typically 95% of the subscriber loops show line lengths

below 2 km. Therefore, a more economical solution which is

optimized to these shorter loop lengths is required.

A time-compression multiplex concept has been chosen

which – for separation of direction – divides the framing into

a transmit and receive section. Taking synchronization bits

and line conditions into account, a clock rate of 384 kbit/s,

twice as high as for the S-bus, has been found to be optimal

with respect to time compression, interference line

attenuation and delay. The transceiver uses AMI coding,

scrambling, automatic gain control and √

-equalizing to

obtain excellent transmission quality.

From a system point of view, the lOM-compatible IBC is

compatible with the IEC or SBC/SBCX as well as with the

EPIC/ELIC and the IDEC on digital line card applications.

Similar to the other components, the device is designed in 2-

µm CMOS technology resulting in low power consumption of

less than 80 mW in the active state.

Features

• Half-duplex burst-mode two-wire transceiver

• 144-bit/s user bit rate (B+B+D)

• 384-kHz line clock rate including maintenance and

synchronization

•U

P0 interface, industry standard for

2-wire PBXs (AMI-line code)

• IOM-interface compatible (IOM-1 or IOM-2)

• Adaptive line equalization (SC filter)

• Recovery of clock and frame signals from data stream

• Activation/deactivation procedure according to CClTT

recommendation

• Awake in power-down mode

• Switching of test loops

• Transmission range up to 3.5 km with 0.6-mm wire

•2-µm CMOS technology

• Low power consumption

Siemens Aktiengesellschaft 128

Overview on Primary Rate Interface (PRI)

Applications for the Primary Rate Interface include trunk lines

between public central office (CO) exchanges, from a PBX

to a CO, interlinking PBXs, the gateway connecting a LAN to

the public network on a PBX, interlinking LANs, interfacing a

large computer or data intensive terminal (e.g. CAD graphics)

with the CO or a PBX etc.

Due to different technical evolutions in Europe and the US

there are two basic interface types for 1st order transmission

systems, the T1 and the CEPT or E1 standard. The ISDN-

PRI is based on these two different standards. The main

difference between ISDN-PRI and T1/CEPT transmission

systems is the type of signaling used.

The T1 standard is based on the PCM24 technique, where

twenty-four 64-kbit/s basic channels and one framing bit are

combined into one 1.544-Mbit/s frame format.

The CEPT standard is based on the PCM30 technique. The

2.048-Mbit/s frame consists of thirty 64-kbit/s basic channels,

one 64 kbit/s signaling channel and 64-kbit/s framing and

maintenance channel.

Siemens Semiconductor Division offers a complete solution

of ICs covering different standards and applications.

The PEB 2236 IPAT®-2 (ISDN Primary Access Transceiver)

and the PEB 2035 (Advanced CMOS Frame Aligner) fulfill

the T1 and CEPT standards. At the system side the ACFA

provides a synchronous PCM interface for connecting to

other application specific ICs (e.g. MTSx, HSCX).

The IPAT-2, together with the ACFA, implement the layer-1

physical interface.

Both devices are programmed via the µP interface to perform

the different standards, applications and maintenance/

service functions.

The IPAT-2 is a monolithic line driver for primary access lines

of either the PCM24 (T1, N. America/Japan) or PCM30

(CEPT, W. Europe) standards. In the receive direction, the

device recovers the clock and data signals from the line and

forwards them to the ACFA.

The IPAT-2 is transparent to the received line code. In the

transmit direction, the device takes the signal received from

the ACFA and forms it into transmission pulses according to

CCITT recommendations for the PCM30 or AT&Ts DMI

specifications for PCM24. Correspondingly, input/output jitter

requirements comply with both CCITT and

AT&T specifications.

Frame alignment for all commonly used framing and

multiframing formats is performed by the ACFA. The device

synchronizes the transmit and receive signals, interfaces the

data rate from the line to the 2.048 Mbit/s or 4.096 Mbit/s

internal highway and codes/decodes one of three selectable

line codes.

For PCM24, this transmission code can be either B8ZS or

AMI-ZCS whereas for PCM30, it is always HDB3. Alarms and

error conditions are reported to the microprocessor via a

maskable interrupt line. The ACFA can also be used for

various signaling schemes. Rather than using the HSCC/

HSCX, signaling information can be handled by a less

intelligent communications controller without programmable

time-slot access. For such devices, the ACFA provides the

required signaling information via special purpose pins.

Additionally, the ACFA has a DMA interface for transferring

signaling information to/from a microprocessor controlled

memory. Finally, signaling data can be accessed directly via

the microprocessor interface.

Siemens new generation of Primary Rate Interface

component, the PEB 2254 FALC54 (Framing And Line

Interface plus signaling Controller), implements the

functionality of a line interface, frame aligner and signaling

controller for both standards E1 and T1 on a single chip.

Applications

In general the following applications can be covered:

• Synchronous/asynchronous multiplexers

• Digital access cross connects

• Central offices switches

• Remote switches, subscribers loop carriers

• LAN, MAN, WAN, Bridges, Routers

• FITL

• PBX interfaces

The following chapter outlines the application of the Primary

Rate devices ACFA, FALC54 and I PAT-2 and shows the

flexibility of the architecture.

In the switching application the Primary Rate Interface is

connected to a switching network of a PBX, CO or

concentrator. The switching devices MTSL (Memory Time

Switch Large), MTSC (Memory Time Switch CMOS) and

MTSS (Memory Time Switch Small) perform the switching

and data rate adaption. In addition to the switching function

the MUSAC (Multipoint Switching and Conferencing) can

handle 64-conference channels in any combination.

and PBXs to host computers for implementations of primary

ISDN subscriber loops as well as for terminal applications.

The maximum range is determined by the maximum

allowable attenuations.

In the T1 case the PRACT’s power consumption is mainly

determined by the line length and type of the cable.

Overview on Switching, Attenuation and Conferencing IC-Family

Supervision and control of the entire system, including

connection set-up, maintenance and testing, is performed

in a powerful central processing unit. Besides this, the

through-switching of PCM channels is done in a switching

network unit, whereas the tasks of a frame alignment unit are

to interface PCM transmission routes with the switching

system.

Digital exchanges put calls through by newly arranging the

speech signals coded with 8-bit words (PCM time-slots). The

code words are transmitted serially on PCM lines. The

sampling frequency of 8 kHz produces PCM frames with a

duration of 125 µs. The transmission rate on the line

determines how many code words (speech channels) can be

accommodated within a sampling period. With a data rate of

2048 kbit/s for example, there are 32 time-slots of 8 bits each.

Four lines with a data rate of 8192 kbit/s have a transmission

capacity of 512 channels.

In a digital switching matrix one distinguishes between two

basic switching principles:

• Time division multiplex

• Space division multiplex

A method that is frequently used involves a combination of

the two principles, this being called space/time division

multiplex. The figure illustrates the different principles.

In time division multiplex only the time-slot is altered during

switching. All signals from a certain input PCM line are

switched to a fixed output line, only the time-slot sequence

may change.

In space division multiplex incoming PCM data are only

rearranged in space. The input time-slot equals the output

time-slot. However, input from one PCM line can be switched

to different output lines.

Wideband Switching

An additional future requirement is wideband switching. In

contrast to voice switching, wideband switching is

optimized for data transmission, e.g. for ISDN H-channels

or “Fractional” T1. 64 kbit/s time-slots are combined for

higher data rates. As a precondition all switched time-slots

have to be output in the same frame. For example

6 time-slots could be combined to a 384-kbit/s bundle.

Multipoint Switching

In a multipoint switching configuration data communication

between terminals can be achieved by connecting all

stations to one or more time-slots and transmitting the

information back. In contrast to audio conferences, data

terminals broadcast to the switching matrix which are

or-connected. With multipoint switching an independent

LAN in a PBX system could be realized.

MTSC

Siemens Semiconductor offers devices which take into

consideration the needs for efficient realization of these

tasks. One of the switching network circuits offered is the

Memory Time Switch in CMOS (MTSC) PEB 2045, which

has the ability to connect any of 512 incoming PCM

channels to any of 256 outgoing PCM channels on a single

chip. A non-blocking switch for 512 time-slots can be built up

with two devices only. A further expansion can be realized

very easily too. Different kinds of operation modes enable the

use of the MTSC PEB 2045 in 2048 Mbit/s, 4096 Mbit/s and

8192 Mbit/s or mixed PCM systems.

As an additional feature the MTSC PEB 2045 together with

an Advanced CMOS Frame Aligner (ACFA) PEB 2035 can

realize the system interface of up to four primary multiplex

access lines.

MTSS

The Memory Time Switch Small (MTSS) PEB 2046 is a

smaller version of the MTSC PEB 2045 performing time/

space switch functions for a non-blocking switch of 256 PCM

channels.

MTSL/MTSL-16

The largest in our family, the Memory Time Switch Large

(MTSL) PEB 2047 is capable of switching up to 1024

time-slots.

The MTSL allows the switching of fractional T1 and data

bundles. The MTSL-16 is a selection for 16-MHz

applications.

MUSAC

Siemens Semiconductor also supplies a solution for

conferencing, the Multipoint Switching And Conferencing

Unit (MUSAC) PEB 2245, which performs the complete

switching functions of the MTSC, and has a signal processor

for handling up to 64 conferencing channels in any

combination. The input and output channels can also be

attenuated individually to achieve best transmission quality.

MUSAC-A

The MUSAC-A is an upward compatible device to the MTSL

and MUSAC. It offers in addition the attenuation and

amplification of every time-slot.

Memory Time Switch CMOS (MTSC)

General Description

The MTSC PEB 2045 is a monolithic CMOS circuit, which

has the ability to connect any of the 512 PCM channels of

16 incoming PCM lines to any of the 256 PCM channels of

eight output lines.

The PCM information for a complete frame is stored in the

4-Kbit speech memory SM, i.e. all of the 512 words with 8 bits

are written into a fixed position of the SM. This is controlled

by the input counter every 125 µs. The words are read using

random access with an address that is stored in a connection

memory CM for each of the 256 output channels. The access

to the CM is controlled by the output counter.

To produce a connection the SM address and the CM

address must be written into the PEB 2045 via a µP interface.

The SM-address contains the time-slots and line numbers of

the incoming PCM words. The CM address consists of the

time-slots and line numbers of the output words.

The PEB 2045 can be connected to 2-Mbit/s, 4-Mbit/s and

8-Mbit/s PCM systems, the device clock may be either

4.096 MHz or 8.192 MHz.

In a second operational mode the PEB 2045 together with the

PEB 2035 (ACFA, Advanced CMOS Frame Aligner) and the

PEB 2235 (IPAT, ISDN Primary Access Transceiver)

implements the system interface of up to four primary

multiplex access lines. This interface can be configured for

2-Mbit/s, 4-Mbit/s and 8-Mbit/s systems; a clock shift for input

and output lines with half clock step resolution is

programmable. Selection of operating modes and

programming is made by writing to the mode register and, via

the Indirect Access Register (IAR), the Clock Shift Register

(CSR) and the General Configuration Register (GCR).

The components PEB 2045 and PEF 2045 are functionally

identical. The difference between the two types lies in the

temperature range. The PEB 2045 operates in the

temperature range 0 to 70 °C, the PEF 2045 in the range

– 40 to 85 °C.

Memory Time Switch Small (MTSS)

General Description

The MTSS PEB 2046 is a monolithic CMOS device which

has the ability to connect any of the 256 PCM channels of

eight incoming PCM lines to any of the 256 PCM channels of

eight output lines.

The input information of a complete frame is stored in the

speech memory SM. The incoming 256 channels

of 8 bits each are written in sequence into fixed positions in

the SM. This is controlled by the input counter in the timing

control block with an 8-kHz repetition rate.

For output, the connection memory (CM) is read in sequence.

Each location in CM points to a location in the speech

memory. The byte in this speech memory location is read into

the current output time-slot. The read access of the CM is

controlled by the output counter which also resides in the

timing control block.

Thus the CM needs to be programmed beforehand for the

desired connection. The CM address corresponds to one

particular output time-slot and line number. The contents of

this CM-address point to a particular input time-slot and line

number (now resident in the SM).

Features

• Time/space switch for 2.048-kbit/s PCM systems

• Switching of up to 256 incoming PCM channels to up to

256 outgoing PCM channels

• Eight input and eight output PCM lines

• Configurable for a 4096- and 8192-kHz device clock

Memory Time Switch Large (MTSL)

General Description

The MTSL PEB 2047 is a memory time switch device.

Operating with a device clock of 4096 kHz or 8192 kHz it can

connect any of 1024 PCM-input channels to any of 512

output channels.

The input information of a complete frame is stored

in the on-chip 8-kbit data memory DM. The incoming

1024 channels of 8 bits each are written in sequence into

fixed positions in the DM. This is controlled by the input

counter in the timing control block with an 8-kHz repetition

rate.

For outputting, the connection memory (CM) is read in

sequence. Each location in CM points to a location in the data

memory. The byte in this data memory location is transferred

into the current output time-slot. The read access of the CM

is controlled by an output counter.

The synchronization of this procedure will be achieved by a

rising edge of the synchronizing pulse SP, which is always

sampled with the falling edge of the device clock.

Different modes of operation are configurable at the PCM-

input interface. Also, 8 PCM-input lines can be synchronized

with individual clock shift values to compensate different line

delays. If more than 8 inputs are used one clock shift value

controls up to two ports at the same time.

The input lines IN8 to IN15 can be used as additional

frame-synchronization inputs FS. After synchronizing the

device by the SP pulse, the FS inputs can be evaluated on a

per port basis. This evaluation procedure is started by a

microprocessor command. As a result the input countervalue

on the rising edge of the FS signal can be read from an

internal register. Thus delay compensation is easily

managed by programming appropriate clock shift values

and/or a possible software offset.

During operation of the chip, a frame length check, which

controls correct synchronization by the SP pulse and

generates an interrupt in case of lost or achieved

synchronization is also supplied.

The standard 8-bit µP interface can communicate with Intel

multiplexed/demultiplexed microprocessors as well as with

Motorola demultiplexed processors. It gives access to the

internal registers and to the control – and data memory. Five

directly addressable registers are provided. All other

registers and the memories are accessed by a simple three

byte indirect access method (similar to the MTSC PEB 2045).

The switching path of the MTSL including input buffer, data

memory, control memory, output buffer and timing control

can be tested in the system by a built-in selftest. After

activating this mechanism it takes 1.25 ms (8192 kHz) until

the result “selftest ok/selftest not ok” can be read from the

internal status register.

After test completion the control-memory is also reset.

In applications where 64-kbit/s channels are combined for

higher data rates (e.g. ISDN H-channels) the MTSL ensures

that all switched time-slots are output in the same frame.

In voice applications where a low delay is important, the

MTSL can be programmed for minimized switching delays.

A World of Applications

Data communication has gained a key role in modern

computer systems. We are on the threshold of an era of total

communication: every (micro)computer unit has to be able to

communicate with other devices – either in synchronous or

asynchronous data transmission mode.

Let us have a look at this rapidly growing world of many

different applications. There are among others the following

applications: telecom, office automation, traffic control,

medical equipment, and factory automation.

Telecom

Todays telephone and telecommunication equipment is

getting more and more digitalized while the older analog units

are being replaced. This means that analog signals are

converted to digital data as soon as possible before being

transferred and processed. Back-conversion is made as late

as possible. Consequently the amount of transferred data in

telecom applications is increasing tremendously. Depending

on the desired data throughput and transmission mode, the

designer always gets the right choice with serial

communication ICs from Siemens. There are a lot of goals to

be met: transfer control by high level transportation protocols,

transmitting and receiving data pockets, time-division

multiplexing in time-slot systems, handling of different data

encoding/decoding schemes, etc.

All these kinds of data transfer can be managed by

SAB 82525 or SAB 82526. These ICs are called High-Level

Serial Communication Controllers Extended (HSCX,

SAB 82525) and Single-Channel High-Level Serial

Communication Controllers Extended (HSCX1, SAB 82526).

They were especially designed for serial communication

interfaces in telecom networks requiring HDLC based

protocols.

Typical HSCX applications are network communication

boards, central D-channel signaling, DMI boards, data-link

controllers in digital mobile radio networks as well as cordless

telephone sets.

Office Automation and

Wide Area Networks (WAN)

Typical ESCC2 (Enhanced Serial Communication Controller

with 2 channels, SAB 82532) applications are

communication boards for workstations and minicomputers

as well as l/O multiplexers, bridges and gateways (X.24,

PRI). ESCC2 can be used for nearly all applications from

terminal adaptors and fast HDLC links to Primary Rate

Interfaces (T1/S2) or ISDN interfaces (SO); using unique

software.

If the designer requires multichannel access, he can save a

tremendous amount of board space by using the highly

integrated eight-channel multiprotocol controller SAB 82538

(ESCC8): four ESCC2s (eight serial channels) in one

package.

Fast LANs

If clock recovery up to 4 Mbit/s is needed (e.g. in fiberoptic

transmission systems), the designer can use ESCC2

(Enhanced Serial Communications Controller, SAB 82532).

Basically, the ESCC2 is a faster 16-bit HSCX with a big

bundle of extra functions. HDLC-data transfer can be

implemented up to 10 Mbit/s. ESCC2 is a multiprotocol

controller which enables designers to use synchronous,

bisynchronous as well as asynchronous, fast data transfer

with one chip on one software basis.

Siemens Aktiengesellschaft 160

Product Overview

Siemens’ family of serial communication controllers

comprises a full range of different ICs. While each of them is

designed to enhanced particular features, together they

compose a wide profile of performance. Thus, most likely our

family of complementary devices offers an ideal solution to

many applications in serial data communications.

HSCX

The High-Level Serial Communications Controller Extended

(HSCX) supports a number of synchronous standardized

protocols and a greater number of proprietary protocols at a

transfer rate of up to 4 Mbit/s. Each of its two channels works

independent of the other. Its specific fields of application are

proprietary HDLC local area networks (LAN).

HSCX 1

The Single-Channel High-Level Serial Communications

Controller Extended (HSCX1) is the single channel version of

HSCX.

ESCC2

The Enhanced Serial Communications Controller (ESCC2) is

a multiprotocol controller offering an extraordinary profile of

protocol options at a high-speed transfer rate of up to

10 Mbit/s for each of its two independent channels.

ESCC2 was developed for the different communication

requirements of wide area network, local area network, small

area network and proprietary network applications.

The result is a communications controller as a standard for

implementing Open System Interconnection (OSI) layers-1

and -2 in all these applications. This fact noticeably reduces

development and system costs.

The board space, for example, is reduced by on-chip collision

detection and resolution, programmable preamble, clock

recovery, the logic for multiple protocols and multiple

encodings, 16- and 32-bit CRC, time-slot, assignment,

queued interrupt status for all important events like receiver

FIFO full, receiver FIFO overrun and end of frame

transmission.

Product Overview

The reduction of the software size, due to the 16-bit Intel or

Motorola processor interface, the direct register accessibility,

large FlFOs, vectorized interrupts and four channel DMA

support lead to higher performance and decrease CPU time

to an absolute minimum.

Less system cost, less development cost, less board

space, less power consumption and high performance in a

proven 1-µm CMOS technology are what you gain by using

this communication genius as a standard for all your

applications.

The following ICs are in development or under definition and

will be available in due time to offer new attractive solutions

for serial communication control.

ESCC8

The eight-channel Enhanced Serial Communications

Controller (ESCC8) offers eight independent serial channels.

Basically it consists of four ESCC2 cores. It is a very suitable

solution for multiprotocol and multichannel applications.

MUNICH32

The Multichannel Network Interface Controller for HDLC

(MUNIC32) is a protocol controller for handling up to

32 data channels of a full-duplex PCM highway. It has been

designed for use in fractional T1 interfaces as well as for

applications in switching systems.

ADMA

The Advanced DMA Controller (ADMA) is a four channel l/O

coprocessor that is optimized to handle data transfers in

either 8-, 16- or 32-bit microprocessor systems. It can

transfer up to 40 Mbytes of data per second in a 20-MHz

system. The ADMA transfers data using single cycle, two

cycle and 32-bit fly by operations and can gather or scatter

data with efficient linked list data chaining, making it one of

the most versatile DMA controllers available today. A smaller,

reduced cost version of the ADMA (SAB 82C257) is also

available.

ASCC8

The ASCC8 is an eight-channel Universal Asynchronous

Receiver/Transmitter (UART). It is optimized to handle eight

high-speed asynchronous channels at rates of up to 2 Mbit/s

in 16-×-oversampling mode. The ASCC8 is ideally suited for

applications that include card-to-card signaling MODEM

pools, asynchronous routers, and simple high speed

point-to-point communications between processing elements

within a large system.

High-Level Serial Communications Controller

Extended (HSCX)

General Description

The HSCX (SAB 82525) has been designed to implement

high speed communication links using HDLC protocols and

to reduce the hard and software overhead needed for serial

synchronous communications.

Due to its 8-bit demultiplexed adaptive bus interface it fits

perfectly into every INTEL or Motorola 8- and 16-bit

microcomputer system.

The HSCX directly supports the X.25 LAPB, the ISDN LAPD-

and SDLC protocols and is capable of handling a large set of

layer-2 protocol functions independently from the host

processor.

The time division capability of the SAB 82525 and other

programmable telecom features make it suitable for time-slot

oriented PCM systems designed for packet switching. Due to

its high speed data transfer and high level protocol support it

fits very well in industrial applications e.g. Iaser printers.

The HSCX1 (SAB 82526), the single channel version of the

HSCX, opens another wide application area.

For an easy access to the wide variety and complexity of

synchronous data transfer Siemens provides a PC based

HSCX evaluation Kit.

The SAB 82525/82526 operates in the temperature range

0 to 70 °C, the SAF 82525/82526 in the range -40 to 85 °C.

Advanced DMA Controller

for 16-Bit Microcomputer Sytems (ADMA)

General Description

The SAB 82258A is an advanced general-purpose four-

channel DMA controller tailored for efficient high speed data

transfer between peripheral devices and memories. It is

either coupled tightly with a companion CPU (local mode) or

working in stand alone applications using the remote mode.

The SAB 82258A is unique among DMA controllers providing

complete direct interfacing to the SAB 80286 as well as to

SAB 80186/188/86/88 bus.

Its four superfast DMA channels transfer rate up to 10 Mbytes

per second are possible. If the maximum transfer rate

reaches as much as 20 Mbyte/second. In addition one of the

DMA channels may be configured as multiplexer channel so

that a large number of low speed peripherals can share the

use of the same channel. The interrupt structure belongs to

the fastest and most versatile ones available. Multiple

SAB 82258A DMAs can be integrated very easily by using a

simple local bus arbiter logic.

The SAB 82258A is the only DMA controller that provides

source or destination-oriented data chaining (two chaining

modes) as well as conditional command chaining (jumps

within channel program based on several conditions).

Asynchronous Transfer Mode (ATM) ICs

Siemens Aktiengesellschaft 173

Introduction

In the last few years, Asynchronous Transfer Mode (ATM)

has made big leaps towards standardization and

practicability.

Acceptance in the market is high, due to the future need of

highspeed networking and seamless internetworking. This

new technology perfectly suits these market demands. ATM

networks offer bandwidth on demand, thus being capable of

matching the user’s data needs from sporadic high-

bandwidth bursts to isochronous constant-bandwidth. ATM

technology offers high-speed networks with various

bandwidths and works with any type of transmission

infrastructure. The very flexible basic structure allows to build

and interconnect high-speed WANs, corporate WANs/MANs,

backbone LANs, or powerful links to desktop terminals.

Traditional telecommunication structures are based on Time

Division Multiplexing (TDM), offering fixed-bandwidth time-

slots. ATM however sends data only when required, i.e.

frames are sent asynchronously. By packing the information

in 53-byte cells, including a 5-byte header containing the

destination address, data is guided through the network

along virtual paths and channels. ATM offers bandwidth on

demand with highspeed transmission ranging from kilobytes

up to gigabytes per second.

Siemens Semiconductor Group addresses the market’s

demand for this kind of network technology by being a driving

force in the standardization activities and providing a

complete ATM chipset to the market. ATM-system designers

are supported by a family of Siemens ATM devices to build all

kind of ATM applications. This ranges from dedicated ICs for

Network or Line Interface Cards to powerful ATM switches

and transmission devices.

Asynchronous Transfer Mode (ATM) ICs

Siemens Aktiengesellschaft 174

Building Seamless ATM Networks

ATM technology is capable of providing powerful networks

for various needs. Such an application could be a large

campus network, just as shown in the figure below. In this

example, several backbone switches, located at different

places, are linked together. However, ATM allows this

network to be managed centrally, since all backbone

switches are configured to logically constitute one single

switch. Workgroups are connected to the backbone via ATM

workgroup switches.

The functionality of the Siemens ATM chipset, such as the

cross connect feature of the ATM-Switching Matrix

PXB 4310, allows members of the same workgroups to

communicate effectively with each other without occupying

the backbone. Only two devices of the Siemens ATM chipset

are required to develop ATM-Network Interface Cards for

PCs and WS, providing seamless access to the network.

ATM-Application Examples

ATM-Workgroup Switch

Instead of using a hub to connect a small number of

computers (workgroup), an ATM-work group switch can be

applied. Data transmission to the computers is handled by

transceiver devices, such as the PXB 4230 for unshielded

twisted pair lines, or PXB 4240 for SDH/SONET lines. The

actual switching function is performed by the ATM-Switching

Matrix (ASM) PXB 4310.

This cell switch features 32 inputs and 16 outputs with cross

connect functionality. The ASM chip is designed to a special

cell format, in order to reduce the pin count and power

dissipation. Up-stream and down-stream conversion from the

standard 53-byte ATM-cell format to this Siemens proprietary

format SLIF (Switch Link Interface) is performed by the ASP

chipset PXB 43201 and PXB 43202.

Product Overview

Introduction

Todays highly complex system development projects make it

necessary to have a powerful development environment

available additionally to the components themselves.

Some of the necessary tools are supplied by the chip

manufacturer himself.

The tools consist of either component evaluation boards or

sometimes even almost ready to copy system designs. Also

software chip drivers are often supplied to ease the

integration of components into a customer’s software design.

In some cases software skeleton solutions or even ready to

use software is supplied to speed up the whole system

design.

Besides the tools supplied by the silicon vendor a lot of third

party tools are available on the market which can efficiently

be used. The support tools supplied by Siemens are typically

designed to be used in conjunction with a PC and third party

software tools giving a very powerful environment.

The application oriented guide describes the different

support tools supplied by Siemens in an application oriented

way and it gives hints to set up a development environment

by adding third party equipment whenever meaningful.

This is an application oriented guide meant to provide a fast

way into the typical development environments customers

need. Such a general approach does of course not

necessarily describe the customers specific environment

exactly. However it describes the most common ones.

in Conjunction with a Line Card Module

The next figure shows a set-up that is used to measure the

SICOFI and SLIC transfer characteristic using a PCM4 by

Wandel & Goltermann. In this configuration the PC

mainboard SIPB 5000, the Line Card module SIPB 5121, the

PCM4 adaptor SIPB 5311 and the SICOFI-4 Board

STUT 2465 are used.

Instead of using the SICOFI-4 Board STUT 2465 also the

SICOFI-2 Board SIPB 5135 or the SLICOFI Board

STUT 3065 may be connected via IOM interface to the Line

Card Module SIPB 5121.

If the STUT 2466 and the SICOFI-4 µC are used together, the

SIPB 5000 and SIPB 5121 are not required. Instead the

microcontroller board EVC50X (Part of STSI 2466 kit) is used

to program the SICOFI-4 µC.

1.3.2 Using the PERCOFI Board STUT 2000

The PERCOFI Board is an universally usable board to

measure the SlCOFl-2 SICOFI-4 or SLICOFI. The PERCOFI

Board is not only to replace the SICOFI testboard

STUT 2060, but also to allow critical performance

measurements.

The following configuration shows a typical line card

application using the STUT 2000 PERCOFI Board and the

SICOFI-2 Board SIPB 5135. The PERCOFI Board is

programmed via the RS232 interface by using the same

trackfiles that are used with the Mainboard SIPB 5000 and

the Line Card Module SIPB 5121 to program the codec

devices.

Instead of using the SICOFI-2 Board SIPB 5135 also the

SICOFI-4 Board STUT 2465 or the SLICOFI Board

STUT 3065 may be connected to the PERCOFI Board

STUT 2000 via IOM interface.

1.3.3 Using the SICOFI Test Board STUT 2060

The SICOFI test board STUT 2060 is a stand-alone board

which offers the possibility of connecting any external

customer specific SLlCs with the SICOFI PEB 2060/2260 for

evaluation of customer specific combinations of SLIC and

SICOFI. The next figure shows a set-up that allows

measurements and tests covering the transfer functions of

the complete subscriber line module.

The board is programmable via an RS232 interface by a

terminal or PC. The registers of the PBC or PIC and SICOFI

can be accessed and therefore the SLIC can be controlled.

With the SICOFI testboard the SICOFI PEB 2060 and

SICOFI-2 PEB 2260 codec filter devices can be tested. The

PCM interface of the board can be connected directly to a

PCM4 Wandel & Goltermann test equipment. This set-up

allows to test the SLIC hardware and to verify the

programmed coefficients, which are calculated with the

SICOFI coefficients program.

Different customer specific SLlCs or ready designed SLIC

boards available from Siemens Semiconductor may be

connected to the SICOFI test board STUT 2060 via a 64-pin

connector.

1.3.4 SLIC Boards to be used with the SICOFI Family

A collection of SLIC babyboards has been designed to be

used with the SICOFI PEB 2060, SICOFI-2 PEB 2260 or

2 Tools for ISDN Basis Rate Line Card Designs

2.1 U Transceiver Development Tool (2B1Q)

Together with the SIPB 5121 Line Card Module the IEC-Q

Reference Board SIPB 2091 constitutes the layer-1

functionally needed for the evaluation of various digital line

card architectures using 2B1Q technique for interfacing with

the U-reference point.

2.2 Introduction to the IEC-Q Reference Board

SIPB 2091, SIPB 2092 and SIPB 2092-H

The IEC-Q Reference Board was developed to demonstrate

the performance of the Siemens IEC-Q (PEB 2091)

U-interface transceiver IC. The IEC-Q (ISDN Echo

Cancellation Circuit) uses 2B1Q code for transmission on U.

A single board can be configured by the user to suit multiple

operation modes such as LT and NT modes. Test points

allow for comfortable monitoring of relevant signals. This

enables the developer to quickly comprehend both the

IC- and U-interface-related signals.

The IEC-Q Reference Board interfaces ISDN transmission

lines and terminal areas providing echo cancellation and

message recovery using digital techniques. Hence the main

use of the IEC-Q Reference Board is to accomplish

performance measurements i.e. bit error rate (BER)

measurements on the ETSI and ANSI defined loops.

The optimized layout of the Reference Board allows for

performance measurements in all operation modes available

with the IEC-Q. The so called hybrid was developed to reach

optimum loop lengths and to cover all 15 ANSI loops as well

as the 8 ETSI defined loops. The figure below shows a typical

configuration with LT and NT 1 where the interconnection

between the two U-transceiver devices is established with

means of a dual lead copper wire (U).

The SIPB 2092 additionally supports the stand-alone

(IOM-2) mode and the µP-interface mode. SIPB 2092-H is

identical to SIPB 2092 except that a P-TQFP-64 package

socket instead of a P-LCC-44 socket is provided. For stand-

alone operation of the IEC-Q, both SIPB 2091 and SIPB 2092

are equally suited.

2.3 Bit-Error-Rate Measurement

with SIPB 5000 Main Board

For bit-error-rate (BER) measurements on U the following

add-on modules are required on the LT side in addition to the

LT IEC-Q Reference Board:

ISDN Terminal Adaptor Module (ITAC) SIPB 5140

LAYER-2 Module SIPB 5120-2

Bit Error Adaptor Module (BEAM) SIPB 5312

The following modules are required for BER measurement

on the NT side in addition to the NT IEC-Q Reference Board:

LAYER-2 Module SIPB 5120-2

Bit-Error-Adaptor Module (BEAM) SIPB 5312

The configuration below describes the use of standard LT/NT

applications for the purpose of BER measurements when

supplemented with two BEAM modules. The figure shows

the complete SIPB system set-up for a BER measurement in

LT-NT direction.

Comments:

For the bit-error-rate measurement the LT is configured in the

LT-512-kHz mode since the BEAM module only supports a

512-kHz-DCL clock rate.

With means of the two BEAM modules the BER test

equipment can be synchronized to the IOM clock rate as well

as insert and extract B1/B2 channel data via IOM. BER

measurement is then accomplished by comparing the

inserted with the extracted data. A line simulator is used for

emulating lines and loops including NEXT noise impairments

in order to run performance tests according to the relevant

specifications (ETSI/ANSI).

3.1 Development Environment

3.1.1 A Typical Development Environment

for Subscriber Line Cards

When using the SIPB 5000 ISDN PC-Userboard system in

conjunction with a line card module, an engineer is capable of

designing his own digital or analog line card board.

The basic module needed to build a line card is either

SIPB 5121 or SIPB 5122. Depending on the requirements for

layer-1 interface (for digital line cards) and/or CODEC filter

(analog line cards) additional modules have to be connected.

The following modules may be combined with the line card

The SIPB 7600 Memory Time Switching Board is a

PC/XT/AT based development tool that helps engineers to

get familiar with switching and conferencing ICs.

Test patterns may be generated on board and put as an input

to the switching and conferencing circuits. When

working with continuous data streams additional modules

(layer-1 modules) have to be connected via a 9-pin-flat cable

to the IOM-2 interface.

3.2 The Different Steps in Development

3.2.1 Designing the Hardware

The SIPB 5000 system can be used as a platform for all

development steps. In a later stage it is of course necessary

to make a cost optimized design. For this a subset of the

board design can be used. All the wiring diagrams are

shipped with the board to speed up this process.

3.2.2 Developing the Software

In a premature stage of a development it is very useful to

verify the design by running program sequences on a similar

hardware platform. To manage this task Siemens offers a

very comfortable menu-driven testing and debugging

software. The package delivered with the userboard allows a

direct access to the chip registers by symbolic names.

Subsequent accesses may be written to a file and run as a

trackfile.

Example trackfiles for different configurations are delivered in

the package and will be a great help to the user in getting

started and to speed up his software development.

4 Tools for ISDN Basic Rate Terminal Designs

4.1 A Typical Development Environment

for an ISDN Phone or TA

The Siemens ISDN PC Board Kit SIPB 7011A is based on a

very modular tool environment. This allows to configure every

existing application just by replacing some modules. The

system can be configured as either a terminal itself or as a

network simulator. It can be used to program and evaluate

the chips but it can also be used to run real software (see

IOS).

The ISDN Telephone Development Board SIPB 8051 is a

more or less ready to copy environment to demonstrate the

terminal system in silicon using the ARCOFI-SP (PSB 2163),

the ISAC-S TE (PSB 2186) and the one-chip controller

SAB 80515 with the ISDN protocol software. An ITAC

(PSB 2110) for the rate adaption as well as an ISAC-P TE

(PSB 2196) for the UPN interface is also onboard.

To set up a development environment for serious

developments it is best to use both an SlPB 7011A kit as a

network terminator being able to simulate the public ISDN

and secondly an SIPB 8051 system as the real development

platform. Both systems should be connected and of course a

PC should be connected to the SIPB 8051 to run a

C-Compiler and to download and debug code.

The Keil C51 professional package (in USA Franklin C51

package) as well as the development package of the

Swedish company lAR Systems (in USA Archimedes) have

been used with the SIPB 8051. Their high level language

debuggers can be used very efficiently with the SlPB 8051.

Both systems should be connected and an 8051 type

C-Compiler and high level language debugger should be

available. Additionally the IOS software should be used as a

very efficient software platform if a public protocol is required.

This software is a very compact software solution. It fits on a

one chip controller without needing additional memory. For

rapid prototyping or PTT approval an E2PROM version of the

80C515A is also available.

The SIPB 8051 can be used as a platform for all development

steps. In a later stage it is of course necessary to do a cost

optimized design. For this a subset of the SIPB 8051 design

can be used. All the wiring diagrams are shipped with the

board to speed this process up.

4.2.2 Developing the Protocol Software

A major task in the design work is the development of the

public ISDN protocol software. To ease this work Siemens

provides the IOS as an almost ready to copy protocol

software kernel. IOS has been designed in C and it can be

ported in nearly all CPU environments. For the development

of ISDN phones or TAs IOS has been ported onto an

80C515. Still it might be necessary to do some modifications

or more likely add some features. The board can immediately

load code but the use of a high level debugger like the Keil

(FRANKLIN) TS51 or the IAR (ARCHIMEDES) C-SPY is

recommended. After loading the target system Monitor down

to the board the debuggers work perfectly. An emulator is

really not required.

4.2.3 Figuring out the ARCOFI-SP Coefficients

for Speakerphone

Siemens Semiconductor Group offers two dedicated,

DSP-based speakerphone realizations ARCOFI-SP

PSB 2165 and PSB 2163.

The first digital speakerphone support was implemented in

the ARCOFI-SP PSB 2165, which already exists since 1991.

A substantial feature of the ARCOFl-SP is to provide means

for minimizing feedback in electrical loops and to

compensate for acoustical couplings. Therefore ARCOFI-SP

offers 23 parameters which are set by software

programming. No further external components or trimming

are required. This half-duplex mode is based on a two point

speech detection, which controls the mode switching within

125 µs.

The speakerphone support of the new ARCOFI-SP

PSB 2163 is based on a “Stronger-Wins” algorithm. Two

speech comparators, one at the acoustic (AE) and one at the

line side (LE), mainly control the switching from one active

mode to another one. They compare permanently the signal

levels of both signal paths and control the influences caused

by the echoes at the acoustic side and at the line side. Once,

a speech detector has detected speech activity, the

comparator switches immediately to the direction where the

speech signal is louder than the other one plus the returned

echo.

This offers the advantage of a completely separate

programming of the sensitivity and of the echo control. The

sensitivity is adjusted by the speech detectors and the

speech comparators control the different feedback paths at

the acoustic side and at the line side.

The ARCOFI-SP allows the control of electrical

feedbacks. It is recommended, however, to have the

majority of the acoustic couplings minimized before, by

an optimum design of the telephone case.

For both ARCOFI-SPs there is very comfortable coefficient

software called ARCOS-SP PLUS which eases and reduces

any optimizations to just a simple task at the PC.

Thanks to the DSP realization, the main operational functions

are all parameterized. This technique offers a high level of

flexibility and reproducibility. An enormous advantage is the

reduction of the optimization time. With a special adaptor1) it

is possible to optimize the speakerphone system using just

one link. The iterated procedure of “Building-up a line →

Testing → Deactivating the link → Opening the telephone

case → Resoldering some RC elements → Closing the case”

is reduced to a comfortable computer session focusing on the

real work: the optimization of the switching behaviour. The

speakerphone maintenance/test function of the ARCOFI-SP

supports the transparency of these modes which are

mentioned above (refer to Application Hints for ARCOFI-SP

Users).

5 Tools for GSM Telephone Designs

5.1 A Typical GOLDplus Development Environment

The development of a GSM handset splits up into

development of GSM hardware and GSM software. Up to a

certain stage development will run in parallel converging

more and more prior to GSM type approval. Hardware

development splits up into development of the baseband part

and the RF part with the RF part requiring considerable

experience and know-how.

Siemens along with its partners offers support for all stages

of both hardware and software development permitting even

newcomers to the GSM arena to get started quickly. For

application of the GOLDplus chip set Siemens offers local as

well as central support from headquarters in Munich. UK

based Symbionics offers development of a complete GSM

hardware according to customer requirements. For

development of the RF hardware they build upon their

profound RF experience. Munich based OPTIMAY offers

mature GSM software with an easily customizable MMI.

The development of a GSM handset requires both optimum

hardware and software development tools to meet time

scales in a rapidly moving market.

Hardware Development

GOLDplus Evaluation System

The Siemens GOLDplus evaluation system comprises all

parts of a GSM full rate and half rate handset. It consists

mainly of the GOLDplusX GSM baseband board and the

GOLDplus GSM RF board as shown in figure 1.

On the GOLDplusX baseband board all Siemens GOLDplus

baseband devices are located including the system controller

GOLD-µC (PMB 2706), the signal processor GOLD-SP

(PMB 2707), the digital-to-analog conversion device GAIM

(PMB 2905) and optionally the half-rate coprocessor

GOLD-SX (PMB 2708). All required memory devices like

FLASH memory and RAM are also found on this board.

Suitable periphery like LCD display and keypad complete the

system to a fully functional handset. The connector to the RF

board carries all baseband I- and Q-signals in both receive

and transmit direction and all RF-control signals from

GOLD-µC.

On the GOLDplus GSM RF board all the Siemens GSM RF

devices are located including the transmitter PMB 2240, the

receiver PMB 2405, the PLL PMB 2307 and the power

amplifier consisting of CGY 92 and CGY 120.

The GOLDplus demo system permits evaluation of all

features of the GOLDplus chip set, both for the baseband as

well as the RF part. By adding the PMB 2708 half-rate

coprocessor the baseband may be upgraded optionally to

half-rate operation. Critical parameters like power

consumption or equalizer performance can be measured.

Cost estimations for a customer handset can be based upon

the bill of materials of the board.

GOLDplusX Baseband Board

Software Development Platform

GOLDplusX board permits the customer getting started

immediately with his GSM software development without

having to wait for his own board prototypes. It provides an

optimum debugging platform not only for the GOLD-µC C166

system controller but also for the DSP cores if customer

specific features have to be implemented in DSP firmware.

Besides getting quickly acquainted with the baseband

functionality the board permits easy and complete control of

the RF-chip set using the GOLD-µC controller functions. This

is especially useful for evaluation and fine tuning of the

RF-board functionality.

6 Tools for DECT-Cordless Telephone Designs

6.1 A typical Development Environment

for a DECT-Home System

For DECT-home system development projects, there is a

complete hardware and software solution available, which

was designed to provide a first prototype to the customer. It

actually covers all the necessary functional blocks and is fully

operational, when connected to an analog telephone

network.

The effort was made in order to speed up the development of

a DECT-home system and to provide a system hardware for

immediate software development. Besides the tremendous

know how, especially on the RF part, which is necessary for

designing DECT phones, it is now the first time that a

european standard protocol has to be matched. The DECT

standard actually defines a very complex layered protocol.

To implement that standard, a tremendous software

development effort has to be made. This part of a DECT

project is considered to be done in parallel to the final

hardware design. The DECT-user board system provides a

hardware development platform today which allows

customer’s software group to start working immediately.

6.2 Development Steps

6.2.1 Designing the Hardware

In order to speed up this process, all the wiring diagrams are

shipped with the boards. Major parts of the hardware shipped

can of course be used for the final design. This is especially

true for the SWUD 1300 RF board. The SWUD 3020E or

SWUD 3025 board respectively has of course to be replaced

by the PMB 2720X or PMB 2725X chip along with the

E2PROM and the PMB 2920 chips. However, their

interconnection can be taken from of the shipped wiring

diagrams of the SWUD board.

The SWUD 1100 board will typically need to be customized

because it is very likely that one wants to use a different

keyboard layout or a customized display etc.

The major parts of the SWUD 1200 board can again be used

to design a real base station telephone line interface.

6.2.2 Developing the Software

A major task in the design work is the development of the

DECT-protocol software. The effort is considered to be

several man years. The SWUD 3500 setup is designed to

A Typical Development Environment for a DECT-Home-System

Siemens Aktiengesellschaft 201

Development Systems for Information Technology

The board can immediately load software, but the use of a

high-level language debugger like the Keil (Franklin) TS51 is

recommended. The monitor program of this third party

software package is already shipped with the board to get

user started more quickly. For most of the software

debugging, an emulator is not really required. But in addition

to the described software monitoring by a software debugger,

there is also a hardware emulator available from Kleinhenz

Electronic. It seems to be a good approach to use the

software debugger for most of the daily work, but to have one

emulator available for tricky real-time debugging and for final

target system software implementations.

Besides hardware, there is also code available to support the

development. There is a low level device driver software

available which controls the chips.

In addition to that, the source code package PRODECT adds

a complete software implementation for a typical home

system. This includes all the layers and saves the above-

mentioned several man years. PRODECT is marketed as a

one time buy out license. It implements the complete DECT

standard, and by using PRODECT the customer’s software

effort is decreased to about 10% for customized

modifications.

7 Tools for Universal RF Circuit Designs

For the various RF circuits there are test boards available for

evaluation. For distinct applications like the DECT-system-

oriented family of user boards a complete RF application has

been put together to complete the baseband tool set as a

system solution.

The SIPB 7520 hardware consists of a PC base board

equipped with an 80188 coprocessor system and an

extender board, the new PRACT Evaluation Board, as shown

in the following figure.

The base board comprises an 80188 microcontroller,

128 Kbyte local RAM and a DP RAM-based interface to the

PC. The PRACT Evaluation Board itself can be used in all

applications using E1 or T1 transmission systems. It reflects

the features of the Siemens components for a typical

application like Primary Access TE, especially the new

PRACT device, which contains in addition to the line

transceiver a powerful clock generator with PLL. Signaling

procedures like CAS or CCS as well as bit-robbed signaling

can also be performed.

8.2 SIPB 7520 Software

The SIPB 7520 software comprises the PC Evaluation

Software, which realizes the general user access to the

Primary Rate Interface system and the Device Driver

Software for the Siemens Communication ICs, which can be

downloaded onto the SIPB 7520 PC Board. The Device

Driver Software contains in addition to a standard HDLC

Device Driver Module for the HSCX two new Device Driver

Modules for the ACFA V4.1 and PRACT supporting E1

(CRC4) and T1 (ESF, CRC6) systems.

The most important devices of the SIPB 7520 PRACT

Evaluation Board are the Advanced CMOS Frame Aligner

(ACFA), the ISDN Primary Access Clock Generator and

Transceiver (PRACT) and the High level Serial

Communications Controller eXtended (HSCX).

The ACFA contains the main parts of the layer-1 functions of

the Primary Rate Interface and performs frame alignment to

the incoming data stream. Its activity is supported by the

PRACT linking the dual rail interface of the ACFA to E1 or T1

transmission lines which may be accessed via the Service

Access Connector (SAC). A dedicated overvoltage

protection circuitry is included and screens against voltage

surges on the physical line.

The HSCX supports optimized high speed data transmission

on DMA or interrupt request using HDLC protocols. It is

employed as signaling controller as well as controller for data

transmission in time-slot oriented transmission systems.

Both channels A and B of the HSCX can be used either for

signaling or for data transmission.

All clocks required by the ACFA and the HSCX are generated

by the integrated clock PLL of the PRACT.

9 Tools for Communication Networks System

Designs

9.1 Datacom Application Board EASY532

The Evaluation & Development System EASY532

provides a hardware and software development tool for

communication system applications with the serial

communication controller SAB 82532 (ESCC2) using the PC

as interface to the user. The relevant features of the

SAB 82532 (ESCC2) are supported.

Due to its original concept the Datacom ESCC2-Userboard

EASY532 assists an engineer in developing his own

applications. It reduces greatly the time spent for hardware

and software development in offering not only a ready-to-use

circuitry but also a plain and reliable software for operating,

modifying, and testing the hardware according to one’s own

pretensions and requirements. Thus using the Datacom

ESCC2-Userboard EASY 532 in a short time leads to a

stable hardware development; it provides level-1 and level-2

software support while creating and testing own application

software.

The hardware is designed such as to fit into an expansion slot

any PC/XT/AT or compatible. Thus after some simple

configuring procedures (e.g. selecting l/O address by means

of switches) and insertion of the board into the PC the circuit

is just ready for use.

This Datacom Application System comprises an SDA 80186

coprocessor system, a PC Interface with 2-Kbyte Dual Port

RAM and the Communication IC ESCC2 from Siemens.

Software for EASY 532

The main features of this powerful integrated Evaluation and

Development Software System are:

• The Device Driver Software consists of a Device Driver

System, including the start-up sode and a run-time library

for the EASY 532 80186-coprocessor system. Over 95%

of the Device Driver Software is written in C and available

in source code.

• The Device Driver Software contains optimized Device

Driver Modules especially written for the Communication

IC ESCC2 from Siemens. These modules demonstrate the

features, power and flexibility of the Siemens

Communication ICs. The Device Driver Modules are

completely written in C. They support the different protocol

modes of the ESCC2, e.g. ASYNC, BISYNC, HDLC/

SDLC.

• An Application Program Interface (API) for the

C language helps writing individual application software

for the PC, communicating via a standard interface (C/l

Mailbox Interface) with Device Driver Software on the

coprocessor board. The program EXAMPLE gives a first

idea of how to apply the C/I Mailbox API in a simple

PC-application program.

• The EASY532 tool comprises Downland, Debugging and

Single Step test features, as well as Sequential Test

capabilities. Its main purpose is to simplify the control and

verification of Device Driver Software developed on the

PC. This driver software can directly be downloaded on the

coprocessor board for real-time applications. Furthermore

the window driven Register Access Editor presents the

Siemens Communication IC ESCC2 in a user-friendly

manner. The time, that has to be spent for learning how the

chip architecture looks like and how the chip works in

principle is reduced to a minimum.

• Application specific software can be developed by the user

using so called “application modules” (→ apm.c,

apm.h). This modules are linked to the Device Driver

Software and downloaded on the Datacom Board, thus

providing a high performance real time data

communication system.

•Line drivers like RS232-, RS422-, RS485-drivers, or even

optical modules can be connected to the EASY 532 board.

Using such drivers or modules different system

configurations can be supported, e.g. Master Slave,

Multi-Master, Point To Point.

Databook “Package Information”

The Siemens Semiconductor Group wishes to

introduce interested readers, practical users, and its

customers to its numerous packages, and to present

information on the subjects directly associated with

packages.

Packaging is becoming increasingly important as a

consequence of larger chips and higher operating

frequencies, not only for the semiconductor

manufacturer but specifically for processors and

customers confronted with a steadily growing variety

of packages with regard to pin count, pin raster and

package sizes. For this reason, product selection

should involve not just the chip but also the packages

and, consequently, subsequent processing in order

to ensure feasibility and economy

The opening section deals with the worldwide pattern

of packages and their future trend, while special

mention is made of the problems facing processors

as a result of increasing package diversification.

Sections 2 to 4 present a detailed discussion of

dimensions, characteristics, and markings of typical

packages from the Semiconductor Group.

In view of its rising importance as a link between the

manufacturer of semiconductors and their processors

a whole chapter (5) has been devoted to packing.

Useful advice on processing devices is contained in

Section 6. The different process stages are

described, and the pros and cons of the different

methods are discussed. Special mention is made of

processing humidity-sensitive ICs and anti-ESD

measures.

A list of packages, completes the Package Data

Book.
