Line Programming

By using line configuration, you can program the parameters for individual lines. The programming
decisions you make for a particular line will only be true for that line and not for the entire telephone
system. You should make a record in Chapter 4 of all programming decisions that you make—it will help
you keep track of what you have done and will help you troubleshoot any problem that might arise later.
NOTE:
A lighted LED next to the programming button for the selection indicates the current
configuration. When a single button provides a toggle (on/off) action, the lighted LED
indicates the active feature.
The first step in any programming sequence is to enter the base level. Once in this mode, you can dial the
feature code for any desired configuration. Enter the base level with the following procedure: press
INTERCOM then dial # 7 4 6 . The last step is to press the SPEAKER button to end the
programming procedure and return the system to normal operation.
To make a line port selection, press a programming button or dial a selection number on the keypad as
detailed in the following chart.
