WARNING:
To avoid possible loss of system programming information, renumber the
system before you program the rest of the options described in this chapter.
The three available system numbering plans listed below appear on System
Planning Form 2a.
Two-Digit. This plan is for systems with fewer than 50 extensions and no
plans to exceed that number in the foreseeable future. Each of the first 58
extension jacks is assigned a two-digit extension number, beginning with
10 and ending with 67. Any remaining extensions are assigned four-digit
numbers, starting with 6700 and ending with 6842.
Three-Digit. This plan is for systems with 50 or more extensions or plans
to grow to that number in the foreseeable future. All extensions are
assigned a three-digit number, starting with 100 and ending with 299.
Set Up Space. This plan is for systems with a need to customize extension
numbers or use extension numbers of varying lengths (one to four digits).
All extensions are assigned four-digit numbers in the 7000 range.
Extension numbers 1000 through 6999 are also available for use when you
renumber.
In all three numbering plans, the system assigns three-digit extension numbers to
pools (Hybrid/PBX only), calling groups, paging groups, remote access codes, the
Listed Directory Number, park codes, and Idle Line Access (Key and Behind
Switch modes). In addition, the system assigns 9 for Automatic Route Selection
(Hybrid/PBX only) and Idle Line Access (Key and Behind Switch only). Zero (0)
represents a special extension number actually a fixed dial code for the
primary operator or QCC queue. Any extension number except 0 can be
renumbered.
Extension numbers can be composed of any combination of digits; however, no
number can begin with 0. Trunk numbers (801 to 880) are considered to be
extensions and can be renumbered.
The system does not provide a message to indicate a successful renumber when
either the two-digit or three-digit numbering plan is selected. For the Set Up
Space numbering plan, the system provides a message indicating that all
extensions are in the 7000 range.

selecting the numbering plan. If you press Home, extensions may
remain in the forced idle condition (indicated when the LED next to
each DSS button is on). To restore extensions to their normal
operating state, restart the system.
