Repeater Loopback (RLB)
The Repeater Loopback command (RLB) loops the signal being sent to the
network back to the DTE Drop/Insert (DSX-1) and data ports. The signal is looped
back as close to the network interface as possible (after it has passed through the
framing circuitry of the DSU/CSU). Framing CRCs and BPVs are corrected.
Procedure
To perform a Repeater loopback:
1. From the top-level menu screen, select Test.
2. From the Test screen, select Lpbk.
3. From the Loopback screen, press the
key until the RLB selection appears
on the screen.
4. Select RLB.
Test Started
appears on Line 2. If a Repeater loopback is already in
progress, the

message appears. If an invalid combination
of loopbacks is in progress, the error message
Invld Test Combo
appears
(see
Table 8-2, Valid Loopback Combinations
, for valid loopback test
combinations).
