Understanding ARS analysis
8
The far-left column of the ARS Digit Analysis Table lists the first digits in the
dialed string. When a user makes an outgoing call, the system analyzes the digits,
looks for a match in the table, and uses the information in the matching row to
determine how to route the call.
dialed string. When a user makes an outgoing call, the system analyzes the digits,

determine how to route the call.
Let’s say a caller places a call to 1-303-233-1000. The switch matches the dialed
digits with those in the first column of the table. In this example, the dialed string
matches the ‘1’. Then the systems matches the length of the entire dialed string
(11 digits) to the minimum and maximum length columns. In our example, the
11-digit call that started with 1 follows route pattern 30 as an fnpa call.

Tip:
The first dialed digit for an external call is often an access code. If ‘9’ is
defined as the ARS access code, the switch drops this digit and analyzes the
remaining digits with the ARS Analysis Table.

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 private network.
