1.5.5.3 CO Line Access
Description
There are three methods of accessing a CO line.
Conditions
• Class of Service (COS) programming determines the CO line groups available for making calls (→ CO
Line Group Number [500]).
• CO Line numbers can be referred on a CO line port basis (→ LCOT CO Line Number Reference [409]).
• Button Assignment
A flexible button can be customized as a G-CO, L-CO, or S-CO button as follows:
It is possible to assign CO lines in the following ways:
– The same CO line to the S-CO button and to a G-CO button
– The same CO line group to more than one G-CO button
– More than one L-CO button
Dialing the CO Line Access number selects a CO button according to the following priority: S-CO → G-
CO → L-CO
• Direct CO Line Access
If an extension user is on-hook when pressing an idle CO button, the proprietary telephone (PT)
automatically enables hands-free operation mode. The user can dial without lifting the handset or
pressing the SP-PHONE or MONITOR button.
• Group Hunting Order for Idle Line Access
An idle CO line is selected from the CO line groups assigned for Idle Line Access. If multiple CO line
groups are available, the CO line group hunting sequence can be determined through system
programming.
• CO Line Hunting Order for Idle Line Access and CO Line Group Access
The CO line hunting sequence in a CO line group (from lowest numbered CO line, from highest
numbered CO line or rotation) can be determined through system programming.
