Chapter 12: Trunk Configuration
MAXCS ACC 6.7.1 Administration Manual 141
The list on the left shows all the configured trunks. The Location format is the same as
in the Trunk View window, that is, Logical Board ID : Channel Number. The logical board
ID is assigned by the system. This ID may change when a telephony board is added into
or removed from the system.
When you select a trunk in this list, the options and parameters for the trunk appear in
the settings in the right side of the window.
Configuring One or Multiple Trunks
To customize trunk characteristics, you work on one trunk at a time. To apply the same
configuration to multiple trunks, use the Apply To button. This opens a list of all trunks,
with all of the trunks selected by default. Select the trunks you want to apply changes
to, then click OK. (Use Ctrl+click and Shift+click to select several trunks.) This applies
changes to multiple trunks for only the attribute or option that you changed.
Setting General Trunk Attributes
Select a channel to view its current attributes. You can then set or change the following
attributes. If an option is grayed out, it is not available for that type of trunk:
• Access Code – Assign a trunk access code to the selected trunk. If you need to use
a trunk access code other than 9, you must first set this up on the Number Plan
tab of System Configuration (see “Setting a System Number Plan” on page 44).
Note: There are two types of access code: Trunk Access Code (TAC) and Route
Access Code (RAC). TAC is a quick and easy way to select which trunk(s) you
would like to dial out from, especially when you want to reserve trunks for a
special dialing purpose. For example, you can set up TAC "7" and assign that
to trunk(s). These trunks will be reserved exclusively for users who know the
TAC "7".
Although TAC is easy to use, it does have limitations especially when you are
located in an area with a complicated dialing pattern or you need to set up
VoIP hop-off dialing.
RAC uses the Out Call Routing table, which has the flexibility to group trunks
into a route, assign routes to a specific dialing pattern, and add/delete digits
from the dialing pattern. It can solve most of the complicated dialing prob-
lems. If your system is using RAC, you can set this TAC field to "None".
