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 button or MONITOR button.
•Group Hunting Order for Idle Line Access
An idle CO line is selected from the trunk groups assigned for Idle Line Access. If multiple trunk groups
are available, the trunk group hunting sequence can be determined through system programming.
•CO Line Hunting Order for Idle Line Access and Trunk Group Access
The CO line hunting sequence in a trunk group (from lowest numbered CO line, from highest numbered
CO line or rotation) can be determined through system programming.
•A company name or customer name can be assigned on a CO line port basis so that the operator or
extension user who is answering the call can view the destination which the caller is trying to reach before
answering. This is useful, for example, when multiple companies share the same operator.
•It is possible to identify the CO line port that has a CO line connected to it. This prevents extension users
from originating a call to a CO line which is not connected.
