Controller T1 simulation

Hello Guys,

                I have 2 2621XM routers. Each of the routers have a T1 DSU/CSU card in each of them. I am trying to simulate configuring DS0-GROUPS and PRI-GROUPS on the controller interface but the only interface selcetion I get is the a serial interface representing the T1 cards when I check the sh run. I am looking for a controller interface like the one below. What am I not doing right?

controller T1 1/0
framing esf
clock source internal
linecode b8zs
pri-group timeslots 1-6,24

Re: Controller T1 simulation

The hardware that you have do not supports controller configuration, nor ds0 or pri group.

So you cannot use it for the purpose.

What do I need to do in order to

accomplish this? I thought that the 2621XM Routers with T1 Cards and Crossover cables would do that.

You need NM-HDV-xxx cards for that.
