IP Series Installation Manual Function 2: CO lines
E.3
Outbound CO line groups
Note: A line can be (a) in one line group, (b) designated as a private line or (c) not assigned.
Outgoing lines, if selected by dialing 9, 8 or 71–76, will be assigned in order from the highest
numbered CO line to the lowest available in the line group. If a CO line is not assigned to a line
group or designated as a private line, it will be an inbound-only line and set to Line Group 0 (press
HOLD to delete the line group number).
Default: All CO lines are in Line 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 pro-
grammed on the phone for the phone to access the line for outgoing calls. (Programming
this line on a second phone allows that phone only to monitor whether the line is in use.)
PRI: special note
Because of the dynamic channel allocation on a PRI span, there is no way to prevent inbound traffic
on any particular channel.
Answer ring assignment
Lines can be directed to be answered at up to 10 extensions, or a department (up to 32 extensions),
a mailbox or an auto attendant branch ID (see “Auto attendant programming,” pages G.1–GG.7);
select these with the scroll keys. The destination can be set to add or drop extensions, departments,
mailboxes or IDs if ringing continues due to no answer.
Example: First ring — Line 1 will ring at the operator’s extension.
Third ring — Extensions 112 and 113 are added.
Fifth ring — The operator’s station is dropped from ringing.
Ninth ring — The call will be answered by the auto attendant.
