The following three types of CO buttons must be used to seize an CO line when making a
call.

• A flexible CO button can be assigned as a Line Access Button (G-CO, L-CO or S-CO)

in either System/Station Programming.  Once a flexible CO button is assigned as a Line
Access Button, it provides the line status condition by lighting patterns and colour
indication.  Please refer to “LED Indication” in this section.

• You can set the G-CO and L-CO buttons on one telephone.  Incoming and outgoing

calls on the line are shown on the button in the following priority.

S-CO > G-CO > L-CO

To support efficient utilisation of CO lines, a group of CO lines (CO line 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 CO line group arrive at the G-CO button.  To
make a CO call, you can access an idle CO line in the group by simply pressing the
assigned G-CO button.

• It is possible to assign the same line to an S-CO button, G-CO button, and L-CO

button.

• It is necessary to program the extension for making and/or receiving calls in CO line

groups.

• When your extension is assigned as an incoming call destination for a CO line, you

cannot receive any incoming outside calls unless a G-CO, L-CO or S-CO button
associated with the line is assigned.

• Station Programming (Section 2)
