Field 1 This field should be translated for both private and public network connections.
Field 2
Field 3
Field 4
The NPA-NXX designator is a 2-digit field and within the range of 1 through
99.
This 3-digit field should contain the Numbering Plan Area (NPA), which is also
referred to as the area code. Assignment is therefore dependent on the particular
location and application.
This 3-digit field should specify the NXX, which is also referred to as the local
exchange code. Permitted values must be those numbers within the range 200
through 999 and must be the office code of the local exchange.
This 1-digit field specifies the thousands digit. When not used, it should contain
(–). When used, digits 0 through 9 may be assigned. Use this field only with
three-digit dial plans. Do not use it with four- or five-digit dial plans.
