I am not sure about your exact req, but if you want to connect that inbetween two Modem (V.35 & G703) back-to-back then you need to use "Stright Cable". And if you want to connect from Modem (V.35 to Router Controller) you need to use the same cable.



Rate if it works.

I am connecting 2 g703 intefaces back to back, ie the e1 cards on the cisco routers, I have used a straight through and crossover cable but im not getting any lights showing, any ideas?

Carl , is your terminology correct, g703 is normally using a coax cable so you just cross xmit to recv and vice versa, if it is e1 card that has utp connection then an e1 crossover cable will work as well as coax.

in a test lan rj45 will work, the cross is different than say a cable crossed for ethernet crossover.
