IVX 20
Function 2: CO lines
The IVX 20 system can operate on a station-by-station basis as a PBX or as a combined KEY/PBX
(default) using standard loop start lines.
If a station has line keys programmed, the user accesses the lines by pressing one of these keys or
by dialing 9 (or 8 or 7). If a station does not have line keys programmed, the user
always accesses CO Lines by dialing 9 (or 8 or 7).
Note: To provide additional visual indication of CO line usage, the display of idle phones will show
on/off-hook line status.
Note: All phone programmable keys are defaulted as a squared key system. Use extension button
mapping (Function 35; see page F.7) to change.
Important:
Where any gray shading ( ) appears in an example, it represents values
either unavailable for programming by the function or unused in the
particular example.
Function 21: CO line programming
• The CO lines are numbered 1–6.
• All CO lines are programmed to route callers during the day mode and then can be programmed
to route callers differently during the night mode. The display will indicate
guish which mode is currently being programmed. Lines that are to be programmed alike can be
grouped to simplify programming.
Example: Here is a completed programming worksheet for incoming calls on line 1 to
ring live to extension 100 but finally answered by the main greeting after nine
rings. (The step numbers correspond to the following explanation.)
The steps are:
Choose CO line(s) to program.
1.
Assign outbound CO line groups.
2.
Assign answer rings.
3.
1. Choose CO lines to program
During this step, you use the first 6 programmable keys to represent CO lines. Select lines to be
programmed by pressing one or more of the programmable keys.
Select the line keys to be programmed alike by pressing one or more programmable keys (a se-
lected key's LED glows green), press # to confirm. After programming the steps outlined in this
discussion for these keys (programmed keys' LEDs will glow amber), select additional line keys to
program alike until all required lines have been programmed (and their keys' LEDs glow amber).
