Gang, I'm the new owner of a Cisco 2821 with 4 VWIC-2MFT-T1 Cards. I'm going to multilink 8 T1 lines until our vendor can get a DS3 in place (we are rural).
All of these will be data. I don't completely understand how to configure the Controller Cards to get serial interfaces.
My current config looks like: For the first controller card, I used channel-group 1 timeslots 1-24. They gave me an int s0/0/0:1 My big question I guess, is with the channel group command. Will I put ALL 4 of my VWIC-2MFT-T1 cards in channel 1 or should each physical card have its own channel?
