a. TributaryLocalLoopback: In the Loopback/V.54 Testing screen, select the slot ID which is on the tributary card in the
local site, then choose LoLbk/ANA[F2].
b. AggregateLocalLoopback: In the Loopback/V.54 Testing screen, select the Aggr/Lo aggregate item in the local site
then choose LoLbk/ANA[F2].

remote site then choose ReLbk/DIG[F6].
Note:"In the E1 module, REM may not be selected because it is only for the V.35 module.
V. 3 5 M o d u le
There are three types of loopback functions for the V.35 Module:
1. Analog (ANA) Loopback
2. Digital (DIG) Loopback
3. Request Remote (REM) Loopback
