So, can I use a crossover cable (twisted pair -rj45)or make a cable(twisted
pair) to have two cisco routers back-to-back if they have built in
dsu/csu's? ; or if one router has a built in dsu/csu and one has what I
think is called a db60? I have this equipment and I think all I need is
the 5in1 card for db60 to db60 (I have the cisco cable for back-to-back) but
I don't have the money for the 5in1 card at this time.

On my ADC/Kentrox T-1 csu/dsus I had to change a dip switch on one of the
two units to get them to function back to back.
