Description
To support efficient utilization of CO lines, a
group of CO lines (trunk group) can be assigned
to a ON button on a PITS telephone. '
When this function is assigned, a DN button on a
PITS serves as the Group CO (GCO) button.
GCO button feature provides better service with
a given number if CO lines.
GCO button can be assigned to a PITS
telephone in conjunction with DIl 1: N feature.
Incoming calls on any CO line in the trunk group
can be directed to a maximum of eight
destinations (extension user, ICM group, pickup
group) simultaneously.
In this case, incoming calls arrive at GCO buttons
on the PITS telephone.
If GCO button is not assigned, incoming CO calls
via DIL 1: N feature arrive at a PDN button on it.
To make an outside call, a PITS telephone user
can access an idle CO line in the group by simply
pressing the dedicated GCO button.
