Function 2: CO lines

The IVX C-Class system can operate on a station-by-station basis as a PBX or as a combined key/PBX
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 24-Key Digital Feature Phone's idle display
will show on/off-hook line status.
Since the system handles call transfer functions efficiently, operating in the PBX mode provides more
programmable feature keys for other uses and the opportunity for glare is greatly reduced.
Note: All phone programmable keys default to being unprogrammed (except on extension 100, where the first
key defaults as a day/night key). Use extension button mapping (Function 35; see page F.6) to assign
line keys system-wide. An individual station's keys can be reassigned using PROG/HELP 2 at that station.
Important: Where any gray shading (■) appears in an example, it represents values either unavailable to
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 D (for day) or N (for night) to
show 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 Integrated Answering Machine on the ninth ring.
(The step numbers correspond to the explanation that begins below.)
CO
Do the following to program the CO lines.
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.
The first six DSS LEDs glow red. Select the COs to program alike and press the # key to
confirm. The LEDs will now glow green.
2. Assign outbound CO line groups
CO lines can be grouped for outbound, pooled access into one of three line groups: 9, 8, or 7.
Note: A line can only be in one line group or designated as a private line.
