This section contains instructions for using the information you recorded on the
worksheet to prepare the ARS tables. The system can have as many as 20 ARS
tables — 16 are programmed and 4 are factory set (Dial 0, Special Number,
Default Local, and Default Toll tables). Of the 16 programmable tables, each may
contain one of the following types of information:
■ 6-Digit Tables. If the cost of calls to another area code varies according to
the exchange, this table can be used to route calls on different trunk pools,
depending on both the area code and the exchange. An area code is the
first entry, and the remaining 99 entries are exchanges within the area
code. The system scans the first six digits of the user-dialed number (area
code and exchange) to route the call.
■ Area Code Tables. These tables are lists of 3-digit area codes. Area code
tables are useful if just one type of line/trunk is used for all calls to each
area code on the list.
■ Local Exchange Tables. These tables list 3-digit exchanges within the
local area code. They can be used to route calls over in-state WATS.
■ 1+7 Tables. These tables contain a list of exchanges within the local area
code that require dialing a
but not an area code before the 7 digits.
Because ARS routing requires care and planning, 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 process.
Planning Form Instructions 4
Complete Form 3f for each trunk pool listed on the ARS worksheet (Form 3e).
NOTE:NOTE:NOTE:
The digits before the blank lines in the Area Code/Exchanges section
represent the table entry number used during programming.
On each copy of Form 3f:
1. Write the table number in the Table No. space (maximum 16). Start with the
number
1 and proceed sequentially.
2. Check the appropriate box under the Type of Table heading: 6-Digit, Area
