[VoiceOps] T1 Crossover Cable

[Faisal Imtiaz]

https://supportforums.adtran.com/thread/4027 

suggests that the cable should be a T1 x-over cable, please note that T1 x-over is not the same wiring as Ethernet x-over cable. 

You can easily make a loopback cable/plug to test each side if needed. (just google for t1 loopback wiring).
