I recently installed a 2 Channelized E1/PRI card on my 2 office routers (both cisco 3640s). The cards come up fine, my E1s are syncing with each other quite fine, but the virtual serial interfaces that are created wont bring up the Line protocol at all ! The s0/0:0 will come up but the line protocols stays down ! My carrier says on his side he is fine. does anyone have an idea of why this is happening ? is there a configuration i am leaving out ?
here is how i have configured my two ends of the E1s:
controller E1 2/0
framing NO-CRC4
channel-group 0 timeslots 1-31
and.
controller E1 1/0
framing NO-CRC4
channel-group 0 timeslots 1-31
my serials are simply :
interface Serial1/0:0
ip address 19x.x.x 255.255.255.252
!
What am I getting wrong exactly please ? clocking is internal on both ends, coding is hdb3 and thats about it.
Please help !
