The Group Calling options assigned through system programming and available
only for calling groups are described below.
The Calling Group Supervisor Position is a direct-line console (DLC) with
Extension Status assigned through system programming. The calling group
supervisor monitors and controls calling group activity by using the LEDs and
programmed buttons on the console or Direct Station Selector (DSS).
The supervisor console should include the following programmed buttons:
One button per calling group member, programmed with the member's
extension on the telephone or an optional DSS.
A Calls-in-Queue Alarm button (either on the console or on a DSS),
programmed with the calling group's extension, for monitoring calls in queue.
If the supervisor manages more than one group, he or she needs a button for
each group.
Status buttons for controlling calling group member availability an Available
button (also called ES Status 0) and an Unavailable button (also called ES
Status 2).
The placement of each telephone in the hunting sequence used by the system
to search for an available calling group member is determined by the order in
which each telephone is assigned to the group during system programming.
When the first call arrives for a calling group after a system is installed or
restarted ("cold start"), the system searches for an available group member
starting with the first telephone assigned to the group during system
programming.
The order im which the system searches for an available calling group member
for subsequent calls can be either circular or linear and is called the "hunt type."
Circular. As subsequent calls arrive, the system searches for an available
calling group member starting with the station after the last station to receive
a call. This ensures that calls are evenly distributed among group members.
The circular order is the factory setting and is used when all group members
have the same responsibilities for handling calls.
Linear. As subsequent calls arrive, the system distributes calls starting with
the first telephone assigned to the group through system programming. This
means that most calls are handled by the first member assigned to the
group. This method is used, for example, when the primary responsibility of
the first calling group member is to take calls and other group members
provide backup.
