Terminating A Ber Test; Using Loopback Tests - Cisco 10000 Series Troubleshooting Manual

Using Loopback Tests

Unless unframed is selected, the BER test runs over the configured framing option for the specified T1
Note
line (ESF or SF). Before running a BER test, you should configure the framing option that is appropriate
to your application.

Terminating a BER test

To terminate a BER test, type:
no t1 t1-line-number bert
where: t1-line-number is 1–28.

Interpreting BER Test Results (continued)
Terminate the BER test running on T1 line 10 on the CT3 line card.
Router(config)# controller T3 1/0/0
Router(config-controller)# no t1 10 bert

Indicates the time the test takes to run and the time
remaining for the test to run.
If you terminate a BER test, you receive a message similar
to the following:
Interval : 5 minute(s), Time Remain : 2
minute(s) (unable to complete)
"Interval: 5 minutes" indicates the configured run time for
the test. "Time Remain : 2 minutes" indicates the time
remaining in the test prior to termination. "(Unable to
complete)" signifies that you interrupted the test.
These four lines show the bit errors that have been detected
versus the total number of test bits that have been received
since the test started and since the last synchronization was
detected.
