We use T1, and I'm not sure of the specific differences (other than speed), but to cross one over just set up with the same signalling on each side and set one to Clock Source=Yes and the other to No. The actual Signalling, Switch, and Framing you use over the final, production E1 will be determined by the telco, but for your crossover test just make sure that both sides match. Second, the encapsulation layer. You can use PPP or Frame Relay, whichever you feel comfortable with. PPP is a bit simpler to set up. Just set both sides to nailed, no authentication. You probably won't have huge amounts of traffic with only two E1 for dialup, so don't use compression. That'll help the processor keep up, and compression likely wouldn't help with a 2mbps link anyway. If you use Frame Relay, one side will be DTE, the other DCE, with everything else the same on each end. >My other plan is to use frame relay on synchronous serial port with V35.
