John

The connection looks like rj45 but a "regular" or Ethernet crossover will absolutely not work. A T1 crossover is significantly different than an Ethernet crossover.

Hai,

What is the type of interface is it a V.35 interface you can check using DCE/DTE cabling.

You should use the same encapsulation bothe end.(one interface shoud be DCE and other interface shoud be DTE)

if its an G703(E1 Controler) interface cable should be made in such a way TX Pair shoud Go to RX,RX Pair should go to TX

TX ----------------- RX

RX ------------------ TX

Hope this helps
