Trunk groups
A trunk group consists of one or more B-channels that are logically grouped.
You can configure up to eight trunk groups. For example, you can configure
each B-channel as a different trunk group
two or more B-channels as a trunk group
A B-channel can be a member of more than one trunk group.
Trunk access codes
Trunk access codes are numbers that are used by the Remote Office 9150 unit to
determine which trunk group to use when routing the call. You must define a
trunk access code for each trunk group.
For example, you can assign trunk access codes #61 and #62, as shown below:
Group 1
Trunk 1
Trunk 2
Trunk access code: #61
If a user dials trunk access code #61, the call is routed (or processed) using
trunks 1 or 2. If trunks 1 and 2 are both busy, the user's call is blocked (the user
receives a fast busy signal).
Note: All trunk access codes are automatically defined in Configuration
Manager with a pound prefix (# in North America) so that there are no conflicts
with host PBX dialing plans. Trunk access codes must be between one and three
digits in length in addition to the pound sign.
For a list of the default trunk access codes, refer to the "Remote Office 9150
Configuration Information—Dialing Plans on page 436.
