Yes, there are. I forget the appropriate standard but your supposed to use individually shielded pairs. HOWEVER, this doesen't become a problem unless your going a really long distance such as 500-1000 feet. The teleco themselves run T1's on 100 pairs that are used as IDFs inside of high rises all the time without trouble.
One thing I have found that can cause errors like this is clocking. Traditionally, point to point spans would require one side set to master clock, the other side set to slave clock. But these days telco's run T1's through multiplexers and while they are not supposed to put clock on to the span, many many times I will have to set both sides to obtain clock from the network.
