T1 Dual Framer LIU

GENERAL DESCRIPTION

FEATURES

The DS2196 T1 dual framer LIU is designed for T1

transmission equipment. The DS2196 combines dual

optimized framers together with a LIU. This

combination allows the users to extract and insert

facility data-link (FDL) messages in the receive and

transmit paths, collect line performance data, and

perform basic channel conditioning and maintenance.

The DS2196 contains all of the necessary functions

for connection to T1 lines whether they are DS1 long

haul or DSX–1 short haul. The clock recovery

circuitry automatically adjusts to T1 lines from 0ft to

over 6000ft in length. The device can generate both

DSX–1 line buildouts as well as CSU line buildouts

of -7.5dB, -15dB, and -22.5dB. The on-board jitter

attenuator (selectable to either 32 bits or 128 bits) can

be placed in either the transmit or receive data paths.

The framer locates the frame and multiframe

boundaries and monitors the data stream for alarms.

The device contains a set of internal registers that the

user can access and use to control the unit’s operation

of the unit. Quick access through the parallel control

port allows a single controller to handle many T1

lines. The device fully meets all of the latest T1

specifications.

Two full-featured framers and a short/long-haul

line interface unit (LIU) in one small package

Based on Dallas Semiconductor’s single-chip

transceiver (SCT) family

Two HDLC controllers with 64-byte buffers that

can be used for the FDL or DS0 channels

Supports NPRMs and SPRMs as per ANSI

T1.403-1998

Can be combined with a short/long-haul LIU or a

HDSL modem chipset to create a low-cost office

repeater/NIU/CSU, or a HDSL1/HDSL2 terminal

unit with enhanced monitoring and data link

control

Supports fractional T1

Can convert from D4 to ESF framing and ESF to

D4 framing

32-bit or 128-bit crystal-less jitter attenuator

Can generate and detect repeating in-band

patterns from 1 to 8 bits or 16 bits in length

Detects and generates RAI-CI and AIS-CI

Generates DS1 idle codes

On-chip programmable BERT generator and

detector

All key signals are routed to pins to support

numerous hardware configurations

PACKAGE OUTLINE

Supports both NRZ and bipolar interfaces

Can create errors in the F-bit position and BERT

interface data paths

8-bit parallel control port that can be used

directly on either multiplexed or nonmultiplexed

buses (Intel or Motorola)
