Using routing to create networking 515
Programming Operations Guide
If a user in New York wants to call Toronto within the network, they dial 6221. The local Business
Communications Manager checks the number against the routing tables and routes the call
according to the destination code 6, which places the call using Route 001.
The call appears on the auto answer line on the Business Communications Manager 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 Private received number. The call now alerts at
telephone 6221 in Toronto.
Note: Network calls that use routes are subject to any restriction filters 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.
Network calls are external calls, even though they are dialed as if they were internal calls. Only the
features and capabilities available to external calls can be used.
When programming a button to dial a Network number automatically (autodial), network calls
must be treated as external numbers, even though they resemble internal telephone numbers.
Routes generally define the path between your Business Communications Manager switch and
another switch in your network, not other individual telephones on that switch.
