Using STP cable will be a definite then.

Is there diagram for breaking out a group of T1s to separate cables?

All I am finding is just the jack pin out. RJ48X
I also see that those jack pin outs have Tip and Ring reversed from the normal USOC Jacks.


So if I wanted to make this capable of 2 additional T1s With a total of 4, could I put all 4 T1's on these 2 cables going up to the suite?
Again, the TXs on one cable and RXs on another, and using Shielded cable?
