Configuring ISDN PRI
Configure the access server interfaces for ISDN PRI lines.
0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins
0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs
Total Data (last 24 hours)
0 Line Code Violations, 0 Path Code Violations,
0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins,
0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs
Note the following:
— The controller must report being up.
— No errors should be reported.
Use Cisco's bit-error-rate-testing (BERT) solution and time-division multiplexing (TDM)
command enhancements to test T1 and E1 facilities.
Use BERT to test the link from the central office to your local access server, or the remote access
server can test the link using pings to the service provider's local interface (connected from the
remote site, looped back at your local site, and returned to the interface on the remote site).
The following example shows how to set up and start the BERT tests. The bert profile 1
command in the following example uses these settings: pseudo-random data pattern 211-0.152,
error threshold of 10^-6 bit rate, error injection none, and total time for the test 20 minutes.
5300(config)# bert profile 1 pattern 211-O.152 threshold 10^-6 error-injection none
duration 20
5300(config)# end
5300# bert controller e1 0 profile 1
5300# show controller e1 0 bert
The TDM subsystem troubleshooting commands are not used during normal system operation.
Instead, the Cisco IOS commands show the current status and settings of the TDM backplane,
enable debug output for display to the user when TDM programming occurs, and provide a set
of test commands to test the functionality of the TDM path. TDM commands are generally used
only by a Cisco technical support representative during troubleshooting data continuity
problems.
For details on these two features (BERT and TDM), refer to the Cisco IOS software
Note
configuration guide and command reference publications. These publications are available on the
Documentation CD-ROM that came with your access server, on the World Wide Web from
Cisco's home page, or you can order printed copies.
Make sure the show controller t1 or show controller e1 output is not reporting alarms or
violations.
