Cisco Systems AS5400XM Configuring a Channelized T3 Feature Card, Gateway# show controller t1 1/7

Step 5 Define the line code.

•For the CT1 controller, use binary 8 zero substitution (B8ZS):

Gateway(config-controller)# linecode b8zs

•For the CE1 controller, use high-density bipolar 3 (HDB3):

Gateway(config-controller)# linecode hdb3

Step 6 Return to privileged EXEC mode:

Gateway(config-controller)# Ctrl-Z

Gateway#

Tip To save the gateway configuration, save it to NVRAM. See the “Saving Configuration Changes” section on page 60.

Verifying Channelized T1 or E1 Controller Operation

To verify that your controller is up and running and that no alarms have been reported, enter the show controller command and specify the controller type, slot, and port numbers:

Gateway# 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.

If you are having trouble, consider these possibilities:

•First check that the configuration is correct. The framing type and line code should match what the service provider has specified. Then check channel group and PRI-group configurations, especially to verify that the time slots and speeds are what the service provider has specified. At this point, the show controller t1 or show controller e1 command should be used to check for T1 or E1 errors. Use the command several times to determine whether error counters are increasing, or whether the line status is continually changing. If error counters are increasing or line status is changing, work with your service provider to resolve the issue.

•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 it is not set properly.

Configuring a Channelized T3 Feature Card

The CT3 feature card offers 28 individual T1 channels (bundled as a T3 line) for serial transmission of voice and data. The CT3 link supports the maintenance data link channel in C-bit parity mode and also in payload and network loopbacks. The T1 interfaces multiplexed in the CT3 link support facilities data link (FDL) in extended super frame (ESF) framing.

Note The CT3 controller numbering convention is slot/port in CLI commands. Feature card slot numbering starts from the motherboard and works up from left to right. Slot 0 is reserved for the motherboard. The feature card slots are numbered sequentially from 1 to 7. The port number value is always 0. Under the CT3 controller, the CT1 controller numbering convention is slot/port:channel in CLI commands. Port numbering values range from 1 to 28.
