Today I inserted a WIC to my Cisco 3745 router.
WIC inserted : VWIC-2MFT-T1
We would be using the 2 T1 slots for Data lines. My configuration for the line is as given below :
controller T1 0/2/0
channel-group 0 timeslots 1-24
& Serial Configuration :
ip address 192.168.248.9 255.255.255.252
But post this, my interface status shows :
Serial0/2/0:0 is up, line protocol is down
What mighht be the issue?
In case of a bi-directional loop provdided by the SP, I am able to see the loop at both ends But on normalising the loop I see the status as "Serial up & line protocol down".
