DESCRIPTION
The DS2196 T1 Dual Framer LIU is designed for T1 transmission equipment. The DS2196 combines
dual optimized framers together with a line interface unit. This combination allows the DS2196 user 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 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. 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.
