DS2196
T1 Dual Framer LIU
www.maxim-ic.com
GENERAL DESCRIPTION
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鈥? short haul. The clock recovery
circuitry automatically adjusts to T1 lines from 0ft to
over 6000ft in length. The device can generate both
DSX鈥? 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鈥檚 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.
