The Worldwide Numbering and Dialing Plan (WNDP) feature is compatible with the standard numbering system that the Defense Communications Agency (DCA) established. WNDP is a dialing system that is used in a Defense Switched Network (DSN). WNDP is similar to Precedence Calling, but the pattern of digits that users dial is different.
The following table shows the format of the dialed digits:
Access digits |
Address digits |
FAC |
Route code |
Area code |
Office code |
Extension |
A |
[[1]X] |
[NXX] |
NXX |
XXXX |
Where:
A is the 2-digit WNDP FAC for the precedence level
1 is a Route Code setup digit.
X is any digit from 0 to 9
N is any digit from 2 to 9
Brackets [ ] indicate optional digits
