I have a 2811 MGCP gateway in a CCM 4.X environment running IOS 12.4(8c). It has a T1 PRI for inbound calls. If I do a show interface on the router is shows the Serial 0/0/0:0 and all other timeslots (1-23) as down/line protocol down. However, the T1 is still registered in CCM and the last event logged in the router is that interface Serial 0/0/0:0 is up.
Since this configured for MGCP, would that cause this apparent contradiction? If I do a show mgcp endpoints they all show as up.
The b-channels are not required for any type of data and are a place holder in IOS. You are worried about the status of these commands:
show isdn status (multiple frame established)
show isdn service ( 0 is good state )
show controller t1
At least that T1 is fine based on that output
if this helps, please rate
