IVX 128 Function 2: CO lines
E.1
Function 2: CO lines
The IVX 128 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
71–76
). If a station does
not
have line keys
programmed, the user
always
accesses CO lines by dialing
9
(or
8
or
71–76
).
Note:
To provide additional visual indication of CO line usage, the phone’s display of idle phones
will show on/off-hook line status.
Since the system handles call transfer and auto attendant 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.9) to assign line keys system-wide. An
individual
station’s keys can be reas-
signed 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
This function allows you to program either analog COs or the T1 COs. Enter
1
for analog CO pro-
gramming or
2
for T1 CO line programming.

1=ANALOG 2=T1
Important:
When you modify the system configuration by changing cards, you will need to re-
program the CO lines.
Default answer ring assignment for CO lines is ID1 (for more on ID branches, see “Function 4: Auto
attendant programming,” beginning on page G.1).
• The CO lines are numbered 1–66. You can connect to the system
either
(a.) up to
42
loop start
CO lines if it has 684 or 612 port cards installed (six lines on each port card)
or
(b.) up to
66
lines
if the system has one or more DLC12 cards.
• The lines installed via TI can be loop, ground, E & M, or DID.
• 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 Main Greeting after
9 rings. (The step numbers correspond to the following explanation.)
