Simple Point-to-point T1 (non-Frame Relay)

Hi, I have two 2600 routers with T1 WICS in them. I configured them with the most basic config, made a T1 cross-over cable and made them talk while in my lab. My service provider told me my circuit (point-to-point) data T1 was ready. I need to use ESF framing and linecode of b8zs. I can't seem to get into the controller command. I am trying to the following command:

controller t1 - the router tells me in valid command at t1. Is this a code problem? Or is there a prerequisite command?

I believe that ESF and B8ZS are the default values and typically default values do not show up in show run. So I would think this is correct.

Depending on the model (and perhaps the card) there are serveral ways to configure the controller. For your 2600 I suggest that you look under configuration of the serial interface and see if there are service-module commands available. If so that is how you would configure the controller.

Re: Simple Point-to-point T1 (non-Frame Relay)

Rick, thanks for a quick response. Router took these commands:

conf t > int s0/0 > service-module t1 framing esf > service-module t1 linecode b8zs

However, if I do show run or show controller I don't see these entries anywhere. Is this correct?
