Planning your telephony services
Nortel Networks strongly recommends that you use the planning tables from the Installation and
Maintenance Guide or the Programming Records spreadsheets to understand what lines and set
numbers (DNs) are available to you. Programming records, which are set up in Microsoft Excel*,
provide a reference for your system programming. These forms are located on the documentation
CD.
Coordinate this information with call planning to assess your system requirements ( “Telephony
feature planning” on page 205 ).
Chart this information to determine how to set up your lines and telephones. “Three basic system
telephony configurations” on page 201 provides examples of three basic, single-office,
configurations on which you can base your planning.
DN lengths and the Start DN are identified during initialization of the system, when you run the
Quick Start Wizard. Ensure these settings are correct before you do any other programming. This
is especially important if your system is part of a network, where your DN length and numbering
plan must match that of the other systems in the network.
The Programming Records are divided into three sections:
• Start-up forms for system programming
• Data forms for the protocols you use to connect your Business Communications Manager to
your business network
• Telephony forms, which you fill out for your system telephony configuration.
