Outside Line Wiring

PREPARING THE NETWORK INTERFACE

The local telephone company provides the telephone numbers for outside lines, as well as an installed network interface that may consist of 1-Line adapters (RJ11-type), 2-line adapters (RJ14-type), or 25-line (50-pin, RJ21-type) connectors.

You can connect the outside lines from the network interface connector to the control unit using D2R cords. The method used to connect the outside lines to the control unit depends on the type of network interface as follows:

1-line adapter (RJ1l-type). This adapter allows one connector for each outside line.

>Label each jack with the telephone number.

2-line adapter (RJ14-type). This adapter connects two outside lines per jack.

>Label each jack with the telephone numbers of its two outside lines.

>Plug a 2-line adapter (267C-type) into each jack.

50-pin connector (RJ21-type). This connector carries up to 25 lines.

>Label the interface with the numbers for the outside lines.

>To extend the network interface to the jack field, refer to the instructions in “Jack Field Wiring” on page 2-33.

Refer to Figure 2-4for examples of network interfaces and adapters.
