Hello Jude,

You ca use the RJ45 cable.

The following document will be of some help in understanding the pinouts of an RJ45 cable :

For the configuration part, you need to first decide the protocol (H323/MGCP).

+5 for Sambit for good answer.  In addition RJ45 is OK for straight through E1/T1 cable as the pinouts are the same, however if you need to use cross-over then you cannot use RJ45 Ethernet crossover and need to use RJ48 where pin 1 is crossed with 4, and 2 is crossed with 5.

HTH,

Chris
