System Renumbering 2
The selection of a numbering plan depends on the customer’s needs. Each of the
systems numbering plans (2-digit, 3-digit, and Set Up Space) allows you to
renumber all or selected extensions. If you do not need to renumber extensions,
skip to the last section of this chapter, “Updating Planning Information”.
In Release 6.0 and later systems (Hybrid/PBX mode only), the Uniform Dial Plan
(UDP) allows you to choose non-local dial plan numbering to specify the
numbering of extensions connected to remote systems in a private network and
allow users on your system to access those extensions as if they were connected
to your own system. When renumbering a system that is part of a private network,
see the Network Reference for information.

CAUTION:

CAUTION:
Before programming the private network ranges, set up the local dial plan. If
the ranges are programmed in the network, and then 2-digit, 3-digit, or
Set Up Space factory settings are used, all network ranges on that switch
are erased.
Before the system is renumbered, the AUDIX Voice Power channel
assignments should be deleted (through AUDIX Voice Power) for the
extensions being renumbered. When the renumbering for the system is
complete, AUDIX Voice Power channels for the renumbered extensions
should be added.
Figure 2–2 through Figure 2–4 list the extension numbers according to the three
numbering plans: 2-digit, 3-digit, and Set Up Space. The numbers are arranged in
blocks according to the first digit. The type of equipment or feature they are
assigned is shown in the block. The shaded areas of the table indicate extension
numbers automatically assigned by the system. The unshaded areas indicate the
extension numbers available for reassignment. Use the appropriate plan-specific
instructions that follow to mark Forms 2a and 2b with extension number assign-
ments.
