There are certain known issues.
CSCtr63427 (should be fixed in your release)
CSCua50697 (show be there too).
Try workaround 2 from CSCua50697
Workaround 2:
Step 1) Upgrade to a fixed-in Cisco IOS version.
Step 2) Issue the following commands (hidden, so tab complete will not
work):
enable
config t
controller <t1/e1> <slot/subslot/port> ! ( example: controller t1
0/0/0 )
hwic_t1e1 equalize
Step 3) Shut/no shut the T1 controller, or reload the router to allow
the CLI to
take effect.
Thanks!
Regards,
Divin
