Purpose

Your system uses the AAR or ARS Digit Conversion Table to change a dialed number for more efficient routing. Digits can be inserted or deleted from the dialed number. For instance, you can tell Communication Manager 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.

ARS digit conversion examples

The ARS digit conversion table 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
Communication Manager 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.
