7-148ADMINISTRATION OPTIONS AND REQUIREMENTS — GENERIC 1

Prefix Mark This field is only used for public network (ARS) applications.

The Prefix Mark relates to the ARS Prefix 1 Required? field on the DIAL PLAN RECORD screen. If the ARS Prefix 1 Required? field is translated y, then (for certain type of calls) it may be necessary to transmit the one along with the dialed digits. The Prefix Mark field permits four different entries (numbers) for administering this capability. Field encodes and their descriptions are:

0Specifies that the prefix digit one is not inserted.

NOTE: This entry is appropriate when there are no Interchangeable CO Codes within the NPA. If the destination number is seven digits or less (for example, NNX-XXXX or a service code N11) then the digits are sent as dialed. Furthermore, for these type calls, if the prefix digit one is dialed it is not deleted. For 10-digit (NPA-NNX-XXXX) calls, if the prefix one is dialed it is deleted.

1Specifies that the prefix digit one is sent if and only if the call is a 10-digit calls. For this entry, there may be Interchangeable CO Codes within the NPA.

2Specifies that the prefix digit one is sent for all 7- and 10-digit toll calls. The associated toll list assigns which office codes are toll calls. For this entry, there may not be Interchangeable CO Codes within the NPA. With this entry, if the customer were to dial a one before a nontoll 7-digit call, the call would route as a toll call.

3Specifies that the prefix digit one is sent for all toll calls, regardless of the number of digits. For this entry, there may be Interchangeable CO Codes within the NPA.
