Terminal, Distributed and Longest Idle Hunting
Technical Manuals Online! - http://www.tech-man.com
Beginning with CPC-B Version 2.0, three types of hunt groups are available:
Terminal, Distributed, and Longest Idle. In addition, CPC-Al1 and CPC-B
Version 2.0 and higher also provide a software-defined pilot extension
number. The software-defined pilot number eliminates the need for the 2 W
450 Ohm resistor required for a pilot number in CPC-A and CPC-B Versions
prior to 2.0.
groups to overflow to a transfer extension. The transfer extension can be the
pilot of another hunt group, the pilot (0) of the attendant group, or a single
Terminal Hunt Groups
When the Terminal method is selected, a call to the pilot number will
repeatedly search hunt group members until the Transfer Timer expires. If *
none of the members is free when the timer expires, the call is transferred to
the transfer extension.
Distributed Hunt Groups .
When the Distributed method is selected, calls are distributed through the
pilot number based on which extension in the group received a call in the last
search. The incoming call begins its search at the next available extension in
the group and then repeatedly searches the group, in sequence, until the
Transfer Timer expires. If none of the members is free when the timer expires,
the call is transferred to the transfer extension.
Longest Idle Hunt Groups
With Longest Idle hunting, a call to the pilot number rings the extension in
the group that has been available the longest.
As with the other two methods, the search then continues through the Hunt
Group until the Transfer Timer expires. If a member does not become
available before the timer expires, the call is transferred to the transfer
An extension is not considered idle if it rings.
