ESI-50L Programming Manual Function 2: CO lines
E.2
Do the following to program the analog CO lines.
1. Choose CO lines to program.
During this step, you use the first four programmable keys to represent CO lines. Select lines to be
programmed by pressing one or more of the programmable keys.
The first four programmable keys’ LEDs will glow red. Select the COs to program alike and press # to
confirm. The LEDs for the selected COs 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 71–76.
Note: A line can only be in one line group or designated as a private line.
Select the line group and press the # key to confirm. Outgoing calls will be assigned from the highest CO
to the lowest available. Or, to delete the line group number (whereupon the line can only receive
inbound CO line calls), press HOLD.
Default: 9 (i.e., all CO lines in Group 9).
Private line
You can designate a line as a private line by entering an extension number, instead of a line group
number, in this step. The line is then programmed as outlined in the following explanation, giving the
private line great flexibility for handling call routing.
Note: A private line can be assigned only to a Digital Feature Phone. A line key must be
programmed on the phone to access the line for outgoing calls. However, a status key can
be programmed on another phone to display the busy/idle condition of a private line.
3. Assign distinctive CO ring tone.
A distinctive CO ring tone overrides the station ring tone for incoming calls. Select one of the six
available tones to enable the feature, or select NORMAL to disable the feature.
Range: 1–6 and normal (disabled). Default: Normal (disabled).
