Hunt Pattern
Use the Hunt Pattern section of the Worksheet to record information how
called numbers are processed through one or more PBXs.
The Hunt Pattern defines which Trunk Group will be accessed when a call
is processed and how the call will be routed through a PBX.

For E&M units, Destination numbers always consist of one or more PBX
Office Codes

. Each Trunk Group defined in the Trunk Data folder can be
associated with a PBX Office Code. When there are two or more Trunk
Groups defined for a single unit, grouped ports can be associated with more
than one PBX by configuring them with the appropriate PBX Codes.
Conversely, the Trunk Groups of several units can be configured with the
same PBX Office Code. This stacks units, creating a single virtual unit
consisting of more ports than are available on a single unit.
When a Trunk Group is associated with a PBX Office Code (Destination
number), it is then associated with a unit Hunt Pattern Number (1, 2, 3, or
4). The Hunt Pattern number is used to configure the Trunk Priority Feature
discussed in the next topic.
From 1 to 4 Hunt Patterns can be defined (e.g. A pattern for each Trunk
Group that has been defined for the unit). The relationship between ports,
Trunk Groups, Hunt Patterns and PBX Office Codes is:
Per Unit Minimum Maximum
Ports 1 4
Trunk Groups 1 4
Hunt Patterns 1 4
PBX Codes (Destination No.) 1 128
It is not possible to direct calls to a specific port within a Trunk
Group.
The default configuration is for one Trunk Group made up of all four ports.
This configuration is defaulted to Hunt Pattern 1 and would be associated
with a single PBX Office Code (Destination number). In the Trunk Priority
folder settings this single group is defaulted to Priority one.
If the default configuration is used, then all that is necessary is to define the
connection characteristics for the single Trunk Group (e.g. Trunk Group 1).
Since no additional Trunk Groups are available, no additional Hunt Pattern
information is required and the Trunk Priority section of this worksheet can
be ignored.
If additional Trunk Groups are defined (e.g. Trunk Group2, Trunk Group 3,
etc.) then Hunt Patterns and Trunk Priorities must be configured.
See the next Topic in this section, “Trunk Priority”.

A Trunk Group is made up of one or more ports (see preceding section, Trunk Data).
37
A PBX Office code is a unique 1 to 8 digit identifier associated with a PBX. This number rather than
the Unit’s IVG Office Code, is used when dialing a PBX extension through an E&M unit.
