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–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.

PACKAGE OUTLINE

Note: Some revisions of this device may incorporate deviations from published specifications known as errata. Multiple revisions of any device

may be simultaneously available through various sales channels. For information about device errata, click here: www.maxim-ic.com/errata.
