5.01 Station Hunting-Circular
Description
Circular hunting is enabled when the last DN in the
huntiong group sets the first DN as the Next Hunt
Station as follows.
Station Hunting provides automatic redirection of
incoming calls to an idle member of a hunt group
when the called extension is busy. Idle extensions
are automatically hunted in accordance with the
hunting sequence set in the system program, and
the call is put through to an idle extension.
The hunting sequence is set by "Extension-
Station", Next Hunt Station.
The group formed by this setting is called a
hunting group.
Busy status applies when Extension is off-hook
and there are no idle PDNs for the extension and
when the extension is Out of Service or in fault
condition.
Circular hunting is enabled when the last DN in the
hunting group sets the first DN as the Next Hunt
Station as follows.

When an incoming call cannot be put through even
after hunting all the extensions belonging to the
hunting group, busy tone is sent to the calling
party.
