Loopback:
Abort
F1
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.

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 port).
1-in-8 – A test pattern consisting of a one (1)
followed by seven zeros (on the network only).
511 – A pseudo-random bit sequence (PRBS) that is
511 bits long (on the data ports only). This is a
9
PRBS 2 –1 test.
