How ARS Works
1. A caller with internal dial tone on an SA button dials the ARS Access
Code (usually 9) and is connected to ARS.
2. The user dials a call.
NOTE:
For 10-digit toll calls, the prefix “1” must be dialed to indicate to ARS
that a toll call is about to be dialed. If the Central Office does not
require the prefix 1 to be dialed for toll calls, the ARS digit absorption
feature may be used to eliminate the prefix as the destination is
dialed.
3. ARS selects the table and route to use for the call as follows:
■ If the telephone is restricted or toll restricted, and the dialed
number is not on an allowed list, or the dialed number is on the
disallowed list, the user receives a system error tone.
NOTE:
Emergency numbers must be on an allowed list to be called
from a call restricted telephone.
■ Initially, all 20 tables are in the list of available tables associated
with the call.
■ If the dialed number is 411, 611, 811, 911, or 10xxx (equal access
code), the call is routed over the main pool. otherwise, the Special
Numbers (N11) Table is eliminated from the list of available tables.
■ If the first digit is not a 1, the Default Toll Table, all Area Code
Tables, all 1 + 7 Tables, and all 6-Digit Tables are eliminated from
the list of available tables.
If the first digit is a 1, the Default Local Table and all Local
Exchange Tables are eliminated from the list of available tables.
