516 Using shared line pools to create a network
N0008589 3.3
Using shared line pools to create a network
Using shared line pools is a powerful and efficient way to create a coordinated dialing plan for a
small network. If the Business Communications Manager systems are close to each other
geographically, you can conserve resources by not duplicating long-distance access. For 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. An Business
Communications Manager user in system A can reach Miami by calling system C and using their
line pool to Miami.
To simplify access between Business Communications Manager 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
In this example, 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 Private received number 434,
and ring telephone 434 with an appearance of the associated target line.
