3-port E3/DS3/STS-1 LIU

with Jitter Attenuator

LOCAL LOOPBACK AND REDUNDANCY MUX

Transmitter

Receivers 1 and 2 have a 4-input MUX as shown in

the adjacent figure. In multiport applications where

redundant channels are required, the receiver MUX

can be configured to provide the necessary

multiplexing functions. This allows the user to use

one port as a redundant monitor for the other port.

The tables below show the register settings for

selecting the desired receiver input source.

When serial interface control is not available, the

respective LPBKx pin for each of the channels can

also be used to activate local loopback mode as

shown below. Note that redundant channel modes

can only be activated using the serial interface.

The Register

Same as LLBKA,B = ‘00’

Control bit, REGEN, should be enabled when using

the register settings to avoid conflict with external

loopback setting pins.

Remote (Digital) Loopback
