UNIFORM NUMBERING PLAN (UNP) - VOICE AND DATA

General Description

In the numbering plan for a network to be configured through the use of Tie Lines, a Uniform Numbering Plan (UNP) is employed. When UNP is employed, a station user from any PBX within the network can call a desired party by using a uniform dialing method based on the UNP.

Station Application

All stations.

Operating Procedure

The following describes two applications of the UNP:

Station Number

As shown in Figure 1, all the stations of each PBX connected using Tie Lines are assigned a Station Number of 3 or 4 digits, and the location of the PBX can be identified by the first two digits of the Station Number.

When this numbering plan is employed, a station user from any PBX within the network can call a desired party using a uniform dialing method.

Office Code and Station Number

When this numbering plan is employed, each PBX in the network is assigned a 1, 2, or 3-digit Office Code and each station in the PBX is assigned a 2, 3, or 4-digit Station Number, as shown in Figure 1. Normally, when calling another station, the calling station dials as follows:

P+/-	xxx-	xxxx
Access	Office	Station
Code	Code	Number

+:	2nd DT
- :	No Tone
x :	0 - 9
p :	0 - 9
