DESCRIPTION

The DS2151Q T1 Single-Chip Transceiver (SCT) contains all of the necessary functions for connection

to T1 lines whether they be DS-1 long haul or DSX-1 short haul. The clock recovery circuitry

automatically adjusts to T1 lines from 0 feet to over 6000 feet in length. The device can generate both

DSX-1 line build outs as well as CSU build outs of -7.5 dB, -15 dB, and -22.5 dB. The onboard 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.

It is also used for extracting and inserting Robbed-Bit signaling data and FDL data. The device contains

a set of 64 8-bit internal registers which the user can access to control the operation of the unit. Quick

access via the parallel control port allows a single micro to handle many T1 lines. The device fully meets

all of the latest T1 specifications including ANSI T1.403-199X, AT&T TR 62411 (12-90), and ITU

G.703, G.704, G.706, G.823, and I.431.
