Private Network Parameters - Nortel BCM50 Configuration Manual

• select an outgoing central office line to access the public network
• use all of the BCM features
Callers in the public network
These callers use the public lines to:
• call directly to one or more BCM DNs
• call into BCM and select an outgoing TIE line to access a private network
• call into BCM and select an outgoing central office line to access the public network
• call into BCM and use remote features
Callers in the private network node
These callers use the private lines to:
• call directly to one or more BCM DNs
• call into BCM and select an outgoing TIE line to access other nodes in a private network
• call into BCM and select an outgoing central office line to access the public network
• call into BCM and use remote features
System numbering and dialing plans
All systems on a private network must coordinate dialing plans, to ensure that calls get directed to
the correct network node. As well, routing becomes more complex, especially if the system is not
an end node and must be configured to relay calls to nodes not directly connected to the system.
The type of dialing plan supported by the network determines whether each node also requires
unique DNs.
