Table Planning Forms
4-46 System Features
Because of the complexity of ARS routing, the instructions for filling out the
planning forms are presented a few steps at a time with examples of completed
forms shown after each group of steps. The instructions begin with the
programmable tables (1 through 16) and introduce the factory-set tables
midway through the completion process.
Locate PBX System Forms 9b, Automatic Route Selection Tables and 9c,
Automatic Route Selection Default and Special Numbers Tables. Complete
Form 9b for each trunk pool listed on the ARS worksheet (Form 9a).
Planning Form Instructions
On each copy of Form 9b:
1. Write the table number in the "Table No." space (maximum 16). Start with
1 and number sequentially.
2. Check the appropriate box under the "Type of Table" heading: 6-Digit,
Area Code, Exchange, or 1 + 7.
If this is a 1 + 7 Table:
Check "not within area code" if users do not need to dial a 1 to each
numbers within their own area code.
Check "within area code" if users need to dial a 1 to reach numbers
within their own area code.
3 . Complete the section of the form headed "Area Code/Exchanges":
If this is a 6-Digit Table, write the area code on the blank line next to
entry 001. Then write each exchange in that area code that people
would call on the numbered lines, beginning with the entry 002.
Up to 99 exchanges can be listed in any oreder. If you need to list
more area codes or exchanged, prepare antoher 6-Digit table.
If this is an Area Code, Exchange, or 1 + 7 Table, write the area codes
or exchanges on the numbered lines, beginning with the entry 001.
Up to 100 area codes or exchanges can be listed in any order,
but area codes and exchanges cannot be on the same table.
Note: The digits before the blank lines represent the table entry number
used while programming.
Example one: If a business plans to use Table 1 to route calls to exchanges
333, 444, and 523 in area code 816, the upper section of the completed
Form 9b will look similar to the one shown in Figure 4-2.
