# Uniform Numbering Plan

## Description

A network Uniform Numbering Plan allows you to use the same digits to reach a station from any location in the network. A network Uniform Numbering Plan has the following characteristics:

- the identity of each station within the network is unique

- the unique identity of a station is equivalent to the digits dialed from all nodes in the network to reach the station.

The use of a Uniform Numbering Plan is recommended (especially for MSDN/DPNSS digital networks).

## Conditions and Feature Interactions

- You can use ARS digit modification provided that it does not destroy the uniformity of the numbering plan.

## Programming

1. Program the network so that each station has a unique identity.
