Description
Use Program 11-01 : System Numbering to set the system's internal (Intercom) numbering plan.
The numbering plan assigns the first and second digits dialled and affects the digits an extension user must
dial to access other extensions and features, such as service codes and trunk codes. If the default number-
ing plan does not meet the site requirements, use this program to tailor the system numbering to the site.
Improperly programming this option can adversely affect system operation. Make sure you thoroughly
understand the default numbering plan before proceeding. If you must change the standard numbering,
use the chart for System Numbering (page 52) to keep careful and accurate records of your changes.
Before changing your numbering plan, use the PC Program to make a backup copy of your
system's data.
Changing the numbering plan consists of three steps:
1. Enter the digits you want to change.
2. Specify the length of the code you select to change.
3. Assign a function to the code selected.
Step 1: Enter the digit you want to change
You can make either single or two digit entries. In the Dialled Number column in the System Numbering
(page 52) table, the nX rows (e.g., 1x) are for single digit codes. The remaining rows (e.g., 11, 12..., etc.)
are for two digit codes.
1. Entering a single digit affects all the Dialled Number entries beginning with that digit. For example, enter-
ing 6 affects all number plan entries beginning with 6. The entries you make in step 2 and step 3 below af-
fect the entire range of numbers beginning with 6. (For example, if you enter 3 in step 2 the entries affected
would be 600-699. If you enter 4 in step 2 below, the entries affected would be 6000-6999.)
2. Entering two digits lets you define codes based on the first two digits a user dials. For example, entering
60 allows you to define the function of all codes beginning with 60. In the default program, only * and # use
two-digit codes. All the other codes are single digit. If you enter a two digit code between 0 and 9, be sure
to make separate entries for all the other two digit codes within the range as well. This is because in the
default program all the two digit codes between 0 and 9 are undefined.
Step 2: Specify the length of the code you want to change
After you specify a single or two digit code, you must tell the system how many digits comprise the code.
This is the Number of Digits Required column in the System Numbering (page 52) table. In the default
program, all codes from 100-899 are three digits long. Codes beginning with 0 and 9 are one digit long.
Codes beginning with * are 4 digits long and codes beginning with # are also 4 digits long.
