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.

Loopback: Abort

All LLB PLB

F1 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.

Abort: Test Name

Prt1 Prt2 Prt3

F1 F2 F3

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.

Test Patterns

Use the Test Pattern commands to send, monitor, and abort test patterns.

Available test patterns are:

QRSS – A quasi-random signal source approximating live data that can be monitored for logic errors (on the network and the data ports).

1-in-8– A test pattern consisting of a one (1) followed by seven zeros (on the

Tnetwork only).

511 – A pseudo-random bit sequence (PRBS) that is 511 bits long (on the data ports only). This is a PRBS 29–1 test.
