I guess this doesn't really make any difference.

As long as one side is a T1 cross over and the other side is a regular 
straight though lan cable, if the jacks are wired correctly, you should 
get AIS briefly, before both lights go out.

You can take a regular straight though cable and plug it into the green 
and the other end into the red.  You should get a yellow AIS light on 
send-in and receive-in.  If you don't, then your jacks are probably the 
issue.

Mine is:

T1 cross over from Red jack to T110P (Going by the picture on the Wiki).
Straight though from Green jack to channel bank.
