Terminal 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

Table 4-8 for valid loopback test combinations).

Aborting Loopbacks

The Abort Loopback command stops all loopback tests

or any selected loopback test currently active on the

DSU/CSU.

To abort one or more loopback tests,

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

2. From the Test screen, select Lpbk.

F1

Test:

Rlpbk Lpbk Ptrns

F2 F3

3. From the Loopback screen, select Abort.

4. From the Loopback Abort screen, press the

desired Function key to abort All or one specific

loopback test. Use the scroll keys, if necessary.

F1

Loopback: Abort

All LLB PLB

F2 F3

If you select ALL, LLB, PLB, DLB, or RLB, skip

Step 5.

5. From the Abort screen, press the Function key that

corresponds to the port for which you want to

abort the test. Use the scroll keys, if necessary.

F1

When abort is complete, the message Command

Complete appears on the Abort screen.

NOTE

If you mistakenly choose to abort

a loopback test that is not

currently running, a Command

Complete message will still

display and the loopback that is

currently active will still be

running. Use the TStat branch to

view the test status to determine if

the abort was successful.
