Numbering the System

Numbering the System

This section describes the assignment of numbers to extensions.
NOTE:
Assigning numbers to calling groups, paging groups, park zones, and remote
access is described later in this book.
The process of numbering extensions consists of the following tasks:
Identifying Extension Jacks. Using the placement of modules in the
control unit as a guide (see the Control Unit Diagram on Form 1),
determine the order in which to connect telephones and other equipment
to the control unit. To do this, identify the extension jack types available
by module and then match system components (for example, operator
positions or telephone types) with the jacks that support them.
Renumbering. If the system-assigned extension numbers are not
appropriate for the customer's business, change them. The system offers
two automatic numbering plans (2-digit and 3-digit numbers), as well as
the option of creating a unique numbering plan with extension numbers
of 1 to 4 digits. Each of these three plans allows renumbering of all or
selected extensions.
Updating Planning Information. Add information to Form 1 and to the
floor plan as appropriate.
This section contains instructions for completing each of these tasks. The
Feature Reference provides detailed information about system numbering and
the three numbering plans.
