Dialing Plans With Shared Line Pools - Nortel Enterprise Edge 2.0 Programming Manual

340 Appendix A: Network Examples
The call appears on the auto answer line on the Enterprise Edge in Santa Clara as 6-
221. Because 6 is programmed as a destination code for Toronto on the Santa Clara
system, another call is placed using route 002 from Santa Clara to Toronto. At the
Toronto system, the digits 6-221 are interpreted as a target line received number.
The call now alerts at telephone 6221 in Toronto.

Dialing plans with shared line pools

Using routes and destination codes is a powerful and efficient way to create a
coordinated dialing plan. Line pools offer an alternate method of creating a dialing
plan or supplementing the routing and destination codes.
If the Enterprise Edge systems are close to each other geographically, you can
conserve resources by not duplicating 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 Enterprise
Edge user in system A can reach Miami by calling system C and using their line
pool to Miami.
To simplify access between Enterprise Edge 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
page 340 will let you create a company directory that uses line pool access codes
and unique DNs of a uniform length
