Answer by Dmitri Abaimov posted 30 Jan 2004 | Dear Daniel,
The equivalent to PCM 30 would be DS1. The cable is normally specified as shielded 2-pair with RJ48S on the ends: pair #1 goes on pins 4 and 5, pair #2 goes on 1 and 2. You can make a RJ48S from what is usually referred to as RJ45 jack/plug. BTW, check with your equipment’s manual if you need crossover or straight through cable. Crossover is simply pair #1 from one end goes to #2 on another and vice versa.
Used on numerous occasions unshielded cable at considerable distances with no problem, so you may give UTP version a thought.
Sincerely,
Dmitri Abaimov, RCDD
