EASY3456-T3 with TE3-LIU

(PEB 3452)

Channelized T3 Termination with DS3

Framer, M13 Multiplexer, T1/E1

Framers and 256 Channel HDLC/PPP

Controller

The TE3-CHATT is a serial communication

controller which multiplexes up to 256 channels

into a channelized DS3 trunk.

The unique integration of T1/E1 framer, M13

Multiplexer and DS2/DS3 framer reduces the

layout complexity, saves cost and board space.

This makes the TE3-CHATT an optimized

solution for line cards at DS3 and higher bit rates,

where access to DSO/DS1 channels is needed.

Infineon's DS3 line interface unit, TE3-LIU

(PEB 3452), completes your linecard.

Market's lowest PCI bus load enables multiple

devices on the PCI bus, and maximizes the

system throughput.

Together with the low level

software driver, this complete

evaluation kit is speeding-up

your development process.

TE3-CHATT Block Diagram

The TE3-CHATT protocol machine handles HDLC, bit- and octet

synchronous PPP and a transparent mode. Rate adoption for time slot

transmission from 64 kbit/s down to 8 kbit/s and the concatenation of

time slots, supporting the ISDN H0, H11, H12 channels is supported. Your

software overhead is minimized due to the optimized descriptor structure well

known from the MUNICH predecessors and the SCC product family.

The integrated DS3 framer, M13 multiplexer and T1/E1 framer cover all impor-

tant specifications and allow a direct connection to a DS3 line interface unit.
