Features and Services
Coordinated Dialing Plan
Coordinated Dialing Plan (CDP) steering codes are expanded to a maximum
of seven digits. The maximum number of digits for a complete CDP DN has
increased from seven to ten (a three-digit steering code followed by a seven-
digit internal DN).
With DNXP, the maximum number of leading digits to be deleted from a
Local Steering Code (LSC) is expanded to seven digits, due to longer CDP
numbers.
Digit and Name Display
If longer DNs are defined, the left most digits may be scrolled out on a digit
display, depending on the size of the display window.
Direct Inward Dialing
Depending on the number of Direct Inward Dialing (DID) digits outpulsed by
the Public Exchange/Central Office (CO), the system can insert a unique
string of prefix digits to the incoming Direct Inward Dialing (DID) digits on
a per DID trunk group basis to form a final internal DN. The number of digits
that can be inserted for a DID (or TIE) trunk group has been expanded from
six to eight digits.
Do Not Disturb
If the Directory Number Expansion (DNXP) package is equipped, DNs can
have up to seven digits.
Electronic Switched Network
With DNXP, a seven-digit Location Code (LOC) call to an Electronic
Switched Network (ESN) switch can be terminated to an internal DN of up to
seven digits. A Digit Manipulation Index associated with a Home Location
Code is used to properly terminate the calls.
Flexible Attendant Directory Number
The attendant DN can have up to seven digits if the Directory Number
Expansion (DNXP) package is equipped.
