At Sangoma we do quite a lot of back-to back T1 and E1
connections. T1 is not a very fussy connection, as the baud
rate is only about 750 kbps.
In our experience, for error free communications you can use
the following rules of thumb:
Up to 50 ft: Flat patch cable
Up to 500 ft: Ordinary twisted telephone cable Cat 5 may be
overkill unless you are going hundreds of feet.
we've faced weird intermittent problems and we suspect it's related to
electrical interference caused by power cables et al in the server rack.
we've seen this with both sangoma and digium cards when attempting to
connect asterisk boxes to carrier E1s provided by the local operator. the
cables used are normal cat5 UTP cables.
