We are upgrading our circuit from 16 channels to a full E1 with 30 channels. I am able to change the pri-group timeslots to 1-31. When I sh ip interface brief I see all the channels displayed. My question is does the int S0/0/0:15 need to be modified to s0/0/0:31 to reflect the other channels or will all the channels still be available under the S0/0/0:15?
Any help would be greatly appreciated. Thank you!
