Yep, They should have put the TX pair in one binder and the RX pair in
another. We run our digital circuits (T1, PRI, BRI) on two 50 pair
shielded cat-5 cable from our Demarc (300 feet away) with all the TX pairs
on one cable and RX pairs on the other. We currently run 7 T1s on that
and 25 ISDN lines without problems. Our Demarc is 1500' of brand new
copper (1200 pair) to a LightSpan and a couple miles of fiber back to the
CO.
