0501 - System Numbering
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 table beginning on page 4-12. In the default
program, all codes from 100-899 are three digits long. Codes begin-
ning with 9 or 0 are one digit long. Codes beginning with * and #
and 2-4 digits long, depending on the function.
If you are programming two digit codes in the PC Program, make
sure the nX entry for Number of Digits Required is the maximum
allowed by any of the two digit codes in the range. This is why the
default Number of Digits Required entry for #X is four digits
long. Even though #1-#9, #0 and ## entries require only two dig-
its, #* requires four. If you inadvertently change #* to 2, you will
no longer be able to enter #*#* to enter the programming mode.
Step 3: Assign a function to the code selected
After entering a code and specifying its length, you must assign its
function. This is the Dial Type column in the table beginning on
page 4-12. The choices are:
Dial Type Entry
0
1
2
3-5
6
7
8
15 (Telephone Program)
OR
F (PC Program)
Changing the Dial Type for a range of codes can have a dramatic
affect on how your system operates. Assume, for example, the site is
a hotel that has room numbers from 100-399. In order to make
extension numbers correspond to room numbers, you should:
- Change the Dial Type for the digit 1 from 1 (Service Code) to 2
(extension number).
- Change the Dial Type for the digit 7 from 3 (not used) to 1
(Service Code).
- In Program 0502, reassign extension numbers on each floor
from 100 to 399).
- In Program 0514, reassign the Service Codes from the 100
series (e.g., 116) to the 700 series (e.g., 716). (Other applications
might also require you to change entries in Program 0511.)
- Check Program 0512 to be sure that the Single Digit Service
Code 04 (digit 7) does not affect any post dial Service Codes
codes in 0514. (Unless you changed codes from their default
assignments, this would not be the case.)
