An RJ48 connector is basically an RJ45 connector with only pins 1,2,4 and 5 terminated for a T-1. I don't recall if there are any other differences. I think just about any short, straight-thru, flat satin cable will work just fine. Many of them have ferrite rings on them for noise reduction, I believe. In a pinch a straight thru Cat 5 cable would work just fine. There may be some technical reasons why you wouldn't want to use twisted pair cable, but I don't know about them. I try not to use UTP unless I have to, though. Someone else here is bound to have more technical details and they can fill in what I've neglected to mention or correct any mistakes I made.
