INTRODUCTION

The DSP1695 Multiservice Access Processor is opti-

mized for central-site equipment that is servicing

Internet and corporate access applications. This

device has a RAM-based architecture to support

upgradability to future standards and enhanced

functionality and features. This RAM-based archi-

tecture allows the DSP1695 to be downloaded to

support various services and capabilities.

The DSP1695 has four processing units with each

unit assignable to any service on any of

128 channels. It utilizes Lucent’s latest processing

technology (0.25 µm ESRAM) to achieve silicon

integration and power savings.

For analog modem services, the DSP1695

supports both V.90 and K56flex standards for rates

up to 56 kbits/s over ordinary phone lines, as well

as older standards. The code to support these

standards is the same as the highly interoperable

code that is being shipped today.

For analog FAX services, the DSP1695 supports

the latest V.34 FAX service, as well as older stan-

dards. This code is the same as the highly interop-

erable code that is being shipped today.

For ISDN data services, the DSP1695 supports

both HDLC and transparent modes on 64 kbits/s

and 56 kbits/s channels. The DSP1695 also sup-

ports auto detection of data over voice calls.

For wireless data services, the DSP1695 supports

ETC2for analog cellular service, V.110 for GSM

service, and IWF functionality for TDMA/CDMA

services.

For Internet telephony services, the DSP1695

provides standard-based algorithms for network

echo cancellation, speech coding/decoding, and

concurrent detection/generation of DTMF tones.

The DSP1695 provides a high-speed, 16-bit host

interface with bidirectional DMA-capable FIFOs to

facilitate data transfer, DSP code downloading,

and real-time control and monitoring.

INTRODUCTION (continued)

The DSP1695 accepts a digital µ-law or A-law TDM data stream from channelized T1/E1 or primary-rate ISDN (PRI) interfaces.

The DSP1695 PCM interface supports speeds up to 8 Mbits/s (128 8-bit channels), which allows the system designer to support

multiple T1/E1 or PRI interfaces on the same TDM bus.

The DSP1695 is available in a space-efficient 160 PBGA package with a 1 mm ball-pitch. The DSP1695 pinout has

been optimized to reduce the routing out of the package.
