7.11.4 Hunting Algorithms
The possible hunting algorithms are:-
HUNT Description
0
No hunting will occur. (e.g. for announcements)
1
Circuit mapping where the timeslot on an incoming circuit group directly relates to
the corresponding circuit in an outgoing circuit group (Note: Only one circuit group
can be assigned to a route in this case).
2
2 way forward where the converter will search from the lowest numbered circuit in
the group with the lowest numbered hunt sequence upwards until it finds an
available outgoing circuit to route on.
3
2 way backward where the converter will search from the highest numbered circuit
in the group with the highest numbered hunt sequence downwards until it finds an
available outgoing circuit to route on.
4
2 way forward (modified) which is the same as two way forward except the starting
point for hunting is the most recent circuit in the route used.
5
2 way backward (modified) which is the same as two way backward except the
starting point for hunting is the most recent in the route used.
6
Group spread where the converter will, based on the last successful circuit selected,
start hunting upwards from the first circuit in the next circuit group in the hunt
sequence.
7
Least used where the converter will start hunting from the first circuit in the circuit
group which has the least number of circuits in use.
8
Most free where the converter will start hunting from the first circuit in the circuits
which has the most number of circuits that are not busy and not blocked.
9
Test call circuit selection. This option allows the selection of the outgoing circuit by
embedding the circuit group number and device within the group as part of the digits
dialled. The device within a group will be the last 3 prefix digits that have been
deleted (the number of delete digits having been specified by the CDDL parameter)
and the group will be the 3
rd
, 4
th
and 5
th
last digits that have been deleted.
E.g. If the route has CDDL = 7 and the called party number digits were
010601612345 then the circuit selected would be group 6 device 16.
