Numbering Plan

12.10
Description
The Emerald ICE Numbering Plan refers to the structure of dialed access to the
various resources that are part of the system. A primary example is the extension
numbers of the system. When one extension calls another, the numbering plan is
the mechanism that facilitates this call. For this reason the Numbering Plan is often
referred to as the system Directory Numbers.
The Emerald ICE allows for a very flexible configuration of numbering for the
various system resources. Resources are defined primarily as "port" oriented
components of the system. A numbering structure specific to the application can
be accommodated. The system resources listed under "Related Features" can be
assigned directory numbers that are customized for the installation.
Although the directory number structure flexibility is provided primarily for
system port resources, some feature access also can be customized. (E.g., Account
Code, Paging Groups, and Speed Dial.) Flexibility in numbering includes: Length
of codes (to access the associated resource) and Leading Digit/Digits assigned to
each resource.
As codes are assigned, the system checks for conflicts and protects against
improper programming of resource Directory Numbers. To successfully
implement changes to the default (factory programmed) Directory Number Plan, a
new code cannot be enter if it is in use elsewhere until it has been deleted from
use in the previous assignment.
Default Settings:
Note 1: Range for "Length" for all items is 1‐5.
Note 2: Range for all "Leading" items is any available, non‐conflicting directory
number.
