trunk access code
A trunk access code is a number that is used by the Remote Gateway 9150 unit
to determine which trunk to use when routing a call. For example, 9 is a
common trunk access code used to obtain an outside line.
Note: All trunk access codes are configured on the Remote Gateway 9150 unit
with a pound sign (# in North America) so that there are no conflicts with host
PBX numbering plans.
trunk groups
A trunk group consists of one or more trunk lines that are logically grouped. You
can configure up to eight trunk groups on the Remote Gateway 9150 unit.
trunk interface modules
Used to route calls over the PSTN. The number of modules you must install on
the Remote Gateway 9150 unit depends on the number of simultaneous calls
you want in host-controlled or locally controlled mode.
