Function 169: Feature set activation

Field 1: Selectable numbering plan template

Warning: Changes to this parameter will result in system initialization, which will erase all programming, voice

messages, greetings, and recordings. System programming backups that are of a different

numbering plan range than the one selected cannot be restored.

This parameter allows the installer to select one of nine pre-defined ranges of extension numbers (see

“Numbering plan selections,” page C.2). However, regardless of which extension numbering range is

selected, feature codes, and CO line groups access numbers will stay the same. Press a scroll key to

select a new numbering plan, or press # to continue. If you select a new numbering plan, you will be

prompted to initialize the system by entering the Installer password.

Note: Initialization will take several minutes to complete.

Ranges: (See page C.2.) Default: 100.
