I'm trying to setup a lab with 3 routers where I'm using VWIC2-2MFT-T1/E1 cards. I'd like to really take advantage of these cards being that they came with the routers. I'm having trouble bringing up the interfaces. I'm showing a serial interface up, line protocol down. Being that I'm using T1 crossover cables and not a DCE/DTE cable, I don't believe the clock rate command will apply here. Am I correct in this assumption? I also tried chaning the encapsulation to PPP, but I still can't bring the interface up. What am I missing? I tried using the 'debug serial interface' but I still need to learn to use it. Any suggestions?
