Configuring T1 and E1 Feature Cards
Verify
To verify that your controller is up and running and no alarms have been reported, enter the show
controller command and specify the controller type, slot, and port numbers:
AS5400# show controller t1 1/7
T1 1/7 is up.
No alarms detected.
Framing is ESF, Line Code is B8ZS, Clock Source is Line Primary.

The controller must report being up.
No errors should be reported.
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 of data continuity problems.
For details on the TDM feature, see the Cisco IOS software configuration guide and

Documentation DVD and on the World Wide Web from the Cisco home page, or you can

First decide if the problem is due to the T1 or E1 line or with a particular channel group. If the
problem is with a single channel group, you have a potential interface problem. If the problem is
with the T1 or E1 line, or with all channel groups, you have a potential controller problem. (See the
"Configuring ISDN PRI" section on page
To troubleshoot your E1 or T1 controllers, first check that the configuration is correct. The framing
type and line code should match to what the service provider has specified. Then check channel
group and PRI-group configurations, especially to verify that the timeslots and speeds are what the
service provider has specified. At this point, the show controller t1 or show controller e1
commands should be used to check for T1 or E1 errors. Use the command several times to determine
if error counters are increasing, or if the line status is continually changing. If this is occurring, you
need to work with the service provider.
Another common reason for failure is the dial-tdm-clock priority setting. The default setting is a
free-running clock that causes clock slip problems if not set properly. (See the
