WAN Connectivity between two routers

[troundy]

In the past, I have connected two routers between T1 Controllers using the clock source as internal on one of them to route traffic. At this time I have a lab situtation that needs connectivity between 2 routers and the only ports I have available are a T1 controller on one router, and an E1 controller on the other router. Is it possible to connect these 2 controllers together to and get routing between them?

There is no direct way to connect T1 to E1 controllers back to back. But yo can find some simulator which can give you T1 line at one end and E1 line at other end and dial from one to other to get connectivity.
