Prefix Mark
This entry is not required for AAR. For ARS, enter a number from
0 to 4 or blank.
Prefix Marks set the requirements for sending a prefix digit 1, indicating a
long-distance call. Prefix Marks apply to 7- or 10-digit Direct Distance Dialing
(DDD) public network calls. A prefix digit 1 is sent only when call type is foreign
number plan area (FNPA) or home numbering plan area (HNPA) in the ARS Digit
Analysis table.
For a WATS trunk, the Prefix Mark is the same as the local CO trunk.
Valid entries Usage

For WATS trunks, the terminating NPA is the same as the
home NPA unless the Local Exchange Carrier requires 10
digits for local NPA calls.
