DS2291

T1 Long Loop Stik


Description

The DS2291 T1 Long Loop Stik recovers clock and data from T1 lines varying in length from 0 to 6,000 feet. It also dejitters the recovered clock and data in compliance with AT&T TR 62411 (Accunet* T1.5 Service Description and Interface specification, December 1990).

Compared to other circuits performing T1 clock and data recovery, the DS2291 requires no tuning or additional circuitry. It is a companion to the DS229 T1 Isolation Stik and compatible with the DS2180A or DS2141A T1 Transceivers, for low-cost, low-power T1 interfacing.

Applications area include Channel Service Units (CSU), T1 monitoring equipment, and T1 test equipment.
