We're attempting to bring up a point-to-point connection E1 to T1 from Telmex. We are using 1841 routers on both ends with a WIC-1T (V.35 cable) to a Watson NTU/DSU. The Serial interface is up. But the line protocol is down.
On router A:
ip address x.X.X.X 255.255.255.252
On router B:
ip address x.x.x.x 255.255.255.252
I have tried HDLC encapsulation, and other configs without success.
Telmex is literally refusing to tell us exactly how the line is provisioned so that we may configure the routers correctly.
Any help would be appreciated.
