Dialing plans for T1 lines
Business Communications Manager has a routing feature that allows you to set up a coordinated
dialing plan with other systems in the public network. The goal is to have a network-wide dialing
plan where all telephone numbers are unique and of a uniform length.
Typically, you use coordinated dialing plans with a network of systems with a three to seven digit
dialing access between them.
Any programming for routing must be carefully planned using tables. For more information about
routing and destination codes, see
“Configuring call routing” on page 331 .
This section deals with applying the programming in network situations.

Dialing plan using public lines
The following illustrations provide an example of how you can record dialing plan information in
a spreadsheet. The example shows dialing plan information for a Toronto system in a network of
three offices: Toronto, Halifax and Vancouver. Without routing, a Business Communications
Manager user in Toronto would have to select a line pool and dial 1-902-585-3027 to reach
extension 27 in Halifax (902). By creating a destination code of 30 and creating a route that uses
the proper line pool and dial out number, the user simply dials 3027. The same feature is available
for Vancouver (604).
In the column Dial out, P stands for pause, a host system signaling option. Press FEATURE 78 to
insert a 1.5-second pause in the dialing string.
