Group-CO (G-CO) button
To support efficient utilization of CO lines, a group of CO lines (trunk group) can be
assigned to a CO button. This button is referred to as Group-CO (G-CO) button. Any
incoming calls from any CO line in the same trunk group arrive at the G-CO button. To
make a CO call, you can access an idle CO line in the trunk group by simply pressing
the assigned G-CO button.
Conditions
• It is possible to assign the same CO line to an S-CO button, a G-CO button and an L-
CO button.
• It is necessary to program the extension for making and/or receiving calls in trunk
groups.
• When your extension is assigned as an incoming call destination for a CO line,
you cannot receive any incoming CO call unless a G-CO, L-CO or S-CO button
associated with the CO line is assigned.

Loop-CO (L-CO) button
All CO lines can be assigned to a flexible CO button on a proprietary telephone. The
assigned button serves as an L-CO button. An incoming call on any CO line arrives at
the L-CO button, unless there are S-CO or G-CO buttons associated with the CO line or
unless the button is already in use. To make a CO call, you simply press the dedicated
L-CO button. Pressing the L-CO button provides the same operation as dialing the
feature number for "Local CO Line Access/ ARS" (default=9).
