DESCRIPTION  
The DS2152 T1 Enhanced Single-Chip Transceiver 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 line 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 internal registers which the user can access and control the operation of the unit. Quick access via the  
parallel control port allows a single controller to handle many T1 lines. The device fully meets all of the  
latest T1 specifications including ANSI T1.403-1995, ANSI T1.231-1993, AT&T TR 62411 (12-90),  
AT&T TR54016, and ITU G.703, G.704, G.706, G.823, and I.431.
