12-Port T1 ECAC Module

The 12-port T1 Echo Cancellation And Compression (ECAC) module supports twelve T1 connections to the Class 5 switch via an RJ-21X port, plus onboard echo cancellation and compression.

The 12-port T1 ECAC module consists of two separate cards (Figure 2–11):

12-port T1 ECAC Processing card—performs T1 ￿processing, plus onboard echo cancellation and

compression.

T1 Transition card—provides twelve T1 interfaces via the ￿RJ-21X port (attached to a patch panel), plus a Line Interface Unit (LIU) that inserts framing and supervision signals into

the T1 data stream.
