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.
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 answer rings
Lines can be directed to be answered at up to 10 extensions. The destination can be set to add
or drop extensions if ringing continues due to no answer. If an inbound call isn’t answered in
four minutes, it will be disconnected.
Example: First ring — Line 1 rings at the operator's extension.
Third ring — Extensions 101 and 113 are added.
Fifth ring — Extensions 100 and 101 are dropped from ringing. Extensions 112 and
113 continue to ring until four minutes have passed since the call began to ring, at
which time the call is disconnected..

Once you have programmed all desired CO lines for day mode, repeat the programming steps
for all desired CO lines for night mode. Default: Answer on ring 1 at extension 100 in both day
and night modes.
Example: During night mode, Line 1 rings Extensions 100 and 101. If unanswered, calls
continue to ring up to four minutes and then are automatically disconnected.
