Single Line Telephone Wiring - Vodavi XTS-IP Installation Manual

System Wiring
Electronic Keyset and Terminal Wiring
Wiring from the ETIB to station jack requires two pairs of wire. The first pair provides the
audio or voice path, the second is for signaling or data path. The DATA pair is polarity
sensitive. Reversal does not harm the keyset or system, but the port does not function
properly when reversed. Power is delivered by applying DC voltage to the center tap of the
coupling transformers of each of the 2 pairs.
