Hello!
I have a 2610 router with an e1 card model NM-1CE1U. I've connected a channelized E1 where I have 2 circuits of 128K configured and one of 512K to be connected soon, not yet. IOS: 12.3.1a IP only
I'm running HDLC to connect through these circuits with the other end (cisco routers also).
I don't have problems with the E1 frame or the 128K circuits, I know they're working OK (I have tested and proved that with the PTT). The problem is that eventhouhg the serialx/x:x interfaces are up, and protocol is up, I can't get connected with remote router.

I checked the config several times and I can't find where the problem is. I have also checked the config on the remote routers and it's also OK.
Here is the config of the router with the E1 card:
