Function 2: CO lines
The ESI-50L 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 24 or 48-Key Digital Feature Phone’s idle
display 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 un-programmed (except on extension 100, where the first key
defaults as a day/night key). Use extension button mapping (Function 35; see page F.13) to assign line keys
system-wide. An individual station’s keys can be reassigned using PROGRAM 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 1–16.
• 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 be answered by the Main Greeting after 9 rings. (The step numbers correspond to the
explanation that begins on the next page.)

Function 211: Analog CO line programming
This function allows you to program the analog COs for both day and night mode. You can select the trunk
groups and ring assignments for a group of COs or individual lines. The steps are:
1. Choose CO lines to program.
2. Assign outbound CO line groups.
3. Assign distinctive CO ring tone.
4. Assign answer rings.
