Features
To support efficient utilization of CO lines, a group of CO lines
(CO line group) can be assigned to a CO button. The function is
referred to as Group-CO (G-CO). The G-CO button works in
conjunction with the DIL 1:N feature. Any incoming call from any
CO line in the CO line group arrives at the G-CO button. To make
an outside call, the user can access an idle CO line in the group by
simply pressing the dedicated G-CO button.
• No G-CO button is originally provided on a proprietary telephone (PT).
It is programmable on a CO button by either system or station
programming.
• It is needed to program the extension for receiving and / or originating
calls on CO lines.
• It is possible to assign the same CO line group to more than one G-CO
buttons on the same PT.
• If Least Cost Routing (LCR) is set, it is overridden by an outgoing call
made by pressing the G-CO button.
• It is possible to assign the same line to an S-CO button and to a G-CO
button.
• Immediate, delayed, no ringing or no incoming call (disable) can be
selected on an extension–CO line basis.
• The digital PT user can choose a desired ringer frequency for each G-
CO button by system or station programming.
