Introduction

I wrote this to keep a track of different cables. I have them here to share.

RJ45 EIA/TIA-T568-A

10/100BaseT Xover

Note how one end is T-568A and the other is T-568B

ISDN Xover

 

There are a few different ISDN pin outs used on RJ45.

This one works on CISCO equipment.

   

ISDN Loopback

I have made many of these to test equipment, and to set up labs to simulate out going and incoming ISDN calls, I have also used them on VoIP Gateways to convert H.323 to and from SIP.
