Installation

Issue 5 August 2005
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.
DCP Line Interface

The DCP line interface is a standard D8W 8-wire modular cord. The 8 line-jack
pins are numbered in increasing order from left to right when facing the jack with
the tab slot down. The following table shows pin assignments for the line cord and
jack block interface.
