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 4-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 3-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
¾
actually a fixed dial code
¾
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 2-digit or 3-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.
!
CAUTION:
Select
Exit
on the console or

on the PC when you have finished
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.
