Thedialing plan at eachEnterprise Edge site isconfigured to determine the call type
based on the digits dialed by the user. If a user in Toronto wishes to dial a colleague
in New York, they dial the 4-digit private DN (such as 6221). The dialing plan
recognizes this as a private network DN, and routes the call using Tie service with
a private numbering plan.
Incoming Tie calls are routed to sets based on the digits received by the network,
which in this case will be the 4-digit private DN.
If a user in either location wishes to dial an external number, they dial ‘9’, followed
by the number (such as 9-555-1212). The dialing plan recognizes this as a public
DN, and routes the call using Public service.
Incoming DID calls will be routed to sets based on the trailing portion of the digits
received by the network. For example, if a public network user dials an employee
in the Toronto office, the network will deliver digits 4167632221. Enterprise Edge
will route the call using the last four digits, 2221.
