Assigning ARS FAC
Be sure the ARS Feature Access Code (FAC) is set up on your system. In the U.S., 
9 is usually the ARS FAC. Users dial 9 to make an outgoing call. 
When a user dials 9 to access ARS and make an outgoing call, the ARS access 
code 9 is dropped before digit analysis takes place. will not be part of the digit 
analysis.

Understanding ARS analysis
With ARS, the switch checks the digits in the number called against the ARS 
Digit Analysis Table to determine how to handle the dialed digits. Your switch 
also uses Class of Restriction (COR) and Facility Restriction Level (FRL) to 
determine the calling privileges.
Let’s look at a very simple AAR and ARS Digit Analysis Table
. Your system...

Examples of digit conversion
Your system uses the AAR or ARS Digit Conversion Table to change a dialed 
number for more efficient routing. Digits may be inserted or deleted from the 
dialed number. For instance, you can tell the switch to delete a 1 and an area code 
on calls to one of your locations, and avoid long-distance charges by routing the 
call over your...

Defining operator assisted calls
Let’s look at how the switch routes an ARS call that begins with 0 and requires 
operator assistance. Remember, the user dials 9 to access ARS, then a 0, then the 
rest of the number.
To see how your switch handles a call to an operator:
1. Type 
display ars analysis 0 and press ENTER. 
The AAR and ARS Digit Analysis Table
 screen...

Defining Inter-exchange carrier calls
Let’s look at how the switch routes an ARS call to an inter-exchange 
(long-distance) carrier (IXC). IXC numbers directly access your long-distance 
carrier lines. 
IXC numbers begin with 1010, followed by three digits, plus the number as it is 
normally dialed including 0, 00, or 1+ 10 digits. These numbers are set up on your...

Restricted area codes and prefixes
Certain area code numbers are set aside in the North American Numbering Plan. 
These numbers are 200, 300, 400, 500, 600, 700, 800, 877, 888, 900. You need to 
specifically deny calls made to area codes 200 through 900 (except 800 and 888). 
You can also deny access to the 976 prefix, which is set aside in each area code for 
pay-per...

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
For example, let’s set up multiple locations for a switch with cabinets in Chicago 
and New York. Location 1 is assigned to the cabinet in Chicago, our main office, 
so Central Standard Time is used for our main location. Location 2 is assigned to 
the cabinet in New York. We’ll define the numbering plan area (NPA) for the 
Chicago and New York...
