Mismatched framing or linecoding Step 1 Use the show controllers t1 privileged exec command to see the
framing and linecoding types currently configured on the MIP
1
card.
Step 2 Compare the configured framing and linecoding with those
configured on the CSU
2
. (Refer to the vendor documentation for
information on how to check the CSU configuration.) The framing
and linecoding configured on the MIP card and the CSU must be the
same.
Step 3 Change the framing or linecoding types as necessary to make them
the same on the MIP card and the CSU.
On the router, use the following controller configuration commands
to configure the framing and linecoding on the MIP card:
c7000(config)#controller t1 interface-number
c7000(config-controller)#framing [esf|sf]
c7000(config-controller)#linecode [ami|b8zs]
On the CSU, consult the vendor documentation for information on
changing the configuration.
