Installation

Please read the CAUTION statement directly below before beginning the

installation. If all connections are correct, plug the adapter into the RJ11C jack to

provide the proper wiring translation to the DCP terminals.

NOTE:

This adapter works ONLY when using a DCP terminal on a

2-wire DCP digital line circuit card (for example, the TN2181 or TN2224). It

will NOT work if you are connecting a DCP terminal to a

4-wire, 4-port, or 4-wire, 8-port DCP line circuit card (such as the TN754B,

TN754, TN413, SN270B, or SN270).

CAUTION:

In a previous installation of the premises line jacks, customers may have

wired the jack connections as bridged or in parallel. These jacks must be

rewired, at customer expense, in order for DCP terminals to function

properly in either 2-wire or 4-wire installations. There must be NO

INTERCONNECTIONS between the wire pairs used for 2-wire and 4-wire

operations. Bridging or paralleling of these pairs can result in damage to the

terminal or can cause the PBX line circuit card to remove power to the

terminal. All interconnections between these pairs MUST BE REMOVED

BEFORE the DCP terminals are connected to the jack.
