Starting a Payload Loopback

The Payload Loopback command (PLB) loops the received signal on the network

interface back to the network. The signal is looped back as close to the DTE

Drop/Insert (DSX-1) port as possible (after it has passed throu gh the framing

circuitry of the DSU/CSU). Framing CRCs and BPVs are corrected.

Procedure

To perform a Payload loopback:

1. From the top-level menu screen, select Test.

2. From the Test screen, select Lpbk.

3. From the Loopback screen, select PLB.

Test Started appears on Line 2. If a Payload loopback is already in

progress, the Already Active message appears. If an invalid combination

of loopbacks is in progress, the error message Invld Test Combo appears

(see Table4-8, Valid Loopback Combinations, for valid loopback test

combinations).
