Understanding ARS analysis

To deny long distance calls to the 200 area code:
1. Type
change ars analysis 120 and press ENTER.
The AAR and ARS Digit Analysis Table screen beginning with 120
appears.
The table in our example shows 2 translations for calls that begin with 120.
First, follow the routing for a long-distance call that begins with 120 and is
allowed. The 120 translation handles all dial strings 1-201 through 1-209, and
there are many matches.
— A user dials 9 120 plus 8 digits (the first of the 8 digits is not 0).
— The switch drops the ARS FAC (9 in our example), looks at the ARS Digit
Analysis Table for 120, and analyzes the number. The switch determines
that the call is a long-distance call and sends the call over route pattern 4.
Now we will follow a call that begins with the restricted area code 200. Only one
string matches this translation.
— A user dials 9 1200 plus 7 digits.
— The switch drops the ARS FAC (9), and looks at the ARS Digit Analysis
Table for 1200. The switch determines that the call type is deny and the call
does not go through.
Using wild cards
You can use wild cards to help separate out calls to certain numbers. Remember,
when you use the wild card x in the Dialed String field, the switch recognizes x as
any digit, 0 - 9. For example, you can restrict users from making calls to a 555
information operator where you might incur charges.
Instructions
To prevent callers from placing calls to long-distance 555 information numbers:
1. Type
change ars analysis 1 and press RETURN.
The AAR and ARS Digit Analysis Table screen beginning with 1 appears.
