example, system A, B, and C are all within the same area code.
System A has a line pool to Santa Clara, System B has a line
pool to Montreal, and system C has a line pool to Miami.
A Norstar user in system A can reach Miami by calling system
C and using that line pool to Miami.
To simplify access between Norstar systems, all line pools that
go to the same destination should have the same line pool
access code. For example, system A and system B both have a
line pool to Ottawa. You can configure both systems with the
same line pool access code for the Ottawa line pool.
A dialing plan similar to the one in the following figure allows
you to create a company directory that uses line pool access
codes and unique DNs of a uniform length.
For instance, the person on system A at telephone 234 can
press an Intercom button and dial 7434.
This means that telephone 234 has dialed the line pool access
code of the trunk to system C, and will receive the dial tone of
system C. The digits 434 then map to the Received number
434, and ring telephone 434 with an appearance of the
associated target line.
Tips -
Network calls that use routes are subject to any
restriction filters that are in effect.
If the telephone used to make a network call has an
appearance of a line used by the route, the call will move from
the intercom button to the line button.
The telephone used to make a network call must have access
to the line pool used by the route.
Routes generally define the path between your Norstar switch
and another switch in your network, not other individual
telephones on that switch.
