For sometime now ive been trying to connect 2 1720 routers together with 1dsu t1 card. I know the T1 crossover cable is correct. But I cant seem to get the configuration right. Ive tried clock rate's service-module commands and just cant get it to work, there has to be something Im missing. I need to get them to work like a DTE and DCE.
Im trying to do the labs for Phase 3 & 4 at home. At school we have the serial WAN cards, DCE and DTE are configured easily. Ive tried packet tracer 4 but it does not always work with option.
