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.
The table below reflects these values:
■ ARS feature access code = 9
AAR feature access code = 8
Private Network Office Code (also known as Home RNX) = 222
Prefix 1 is required on all long-distance DDD calls
Dashes (-) are for readability only
The switch maps the dialed digits to the matching pattern that most closely
matches the dialed number. Example: If the dialed string is 957-1234 and
matching patterns 957-1 and 957-123 are in the table, the match is on pattern
957-123.
