The PAC (Prefix Access Code) is the code entered in the numbering plan ( GNP and PNP). A call can only be routed if the dialed digits are matching a PAC.
A Prefix Access Code defines the dialing sequence of a number plan for E.164 and PNP. This table translates prefix codes, feature access codes, speed codes, and other access codes, and determines the nature of address (NOA).
Prefix Access Codes are created to define single digits or strings of digits that enable callers to select specific networks, number formats, and services. For example, a caller uses an international Prefix Access Code to indicate that the subsequent digits in the dialed number identify an international public telecommunication number.
A simple prefix access code transforms an extension to international format and forward that number to the global numbering plan, where a common routing on the base of international numbers should be performed.
When the subscriber creates a Prefix Access Code, he/she has to specify the following properties:
The type of the Prefix Access Code. Possible Prefix Access Code types are:
Vertical Service — vertical service code or feature access code.NOA (Nature of Address):
The VSC (Vertical Service Code) feature provides for user-dialed codes, such as FAC (Feature Access Codes), that allow access to features and services. Services invoked by VSCs include Lotus Sametime Unified Telephony-based station call forwarding, customer-originated trace, and many others.
For more information about the available services for Vertical Service selected as Prefix Type, see the table below.
Speed Calling — The Speed Calling service enables subscribers to dial telephone numbers using fewer digits than is normally required. The subscriber dials a Speed Calling code to reach a frequently dialed number. The Speed Dialing feature allows intercom numbers and access codes + DN (e.g., 9 + DN) in the speed dial list.
Invalid Code — a digit prefix that must be blocked.
Extension Dialing — internal extension number prefix.
The extension dialing feature allows a subscriber in a business group to dial other subscribers in the same business group by dialing an abbreviated number that is synonymous with the extension number.
Off-net Access — A prefix access code to permit access to remote destinations using facilities provided by the PSTN or a third-part service provider.
On-net Access — A prefix access code to permit access to remote destinations using the customer's private network, which may include TDM trunking, LAN, and WAN facilities.
Attendant — attendant access code.
Private Facility — private facility access code.
indicates the NOA value to be associated with the resulting number, after digit deletion and insertion is complete. The assigned NOA value can be used as a factor in subsequent routing and translation steps. Possible values are:
Unknown — The NOA is Uknown.
Subscriber — The DN is an E.164 susbcriber number that does not include the country code or area code.
National — The DN is an E.164 national number that includes the area code, but does not include the country code.
Interantional — The DN is an E.164 international number that includes both the country code and the area code.
PNP Level 0 — The number is PNP Level 0 (subscriber) number. The L0 is mapped by UCE to QSIG TON/NPI of subscriber number, private numbering plan.
PNP Level 1 — PNP L1: The number is PNP Level 1 (national) number. The L1 is mapped by UCE to QSIG TON/NPI of national number, private numbering plan.
PNP Level 2 — The number is PNP Level 2 (international) number. The L2 is mapped by UCE to QSIG TON/NPI of international number, private numbering plan.
PNP Extension — The number is an extension number in Private Numbering Plan. The Prefix Type E.164 Prefix Extension, along with DN Minimum Length and DN Maximum Length should determine the extension number.
Values selectable from a drop-down list depend on the prefix type selection as follows
If the prefix type is Vertical Service, Invalid Code or Speed Dialing , Invalid Code this field is unused and therefore set to Unknown (by default). That means that the address has an unknown DN. There are no further options available.Destination Type:
If the prefix type is Extension Dialing, the options for the NOA are PNP Extension (by default), Unkown, National and International
If the prefix type is Attendant, the options for the NOA are Unknown (by default) or National, Subscriber and International
If the prefix type is On-Net Access or Off-Net Access or Private Facility, the options Unknown (by default) or Local Subscriber, National, International, PNP Level 0, PNP Level 1 and PNP Level 2 are valid.
The Destination with which to associate the Prefix Access Code. The Destination Type indicates how to route the call. Supported destination types are:
None — destination cannot be determined yet. The results from the prefix access code translation are passed to the destination table of this numbering plan. None means the resulting digits will be processed in the user's numbering plan's destination codes table.Destination Name:
Destination — The call is routed directly to a named destination, which must have been defined already in the routing database. A named destination is typically a gateway.
BG Common Destination — BG Common Destination means that the resulting digits after modification will be offered to the user's business group's common numbering plan and E164 Destination means that the resulting digits after modification will be offered to the E164 numbering plan.
Service — The output goes to a “service destination” which is one of the predefined system features (like call forward activation).
E.164 Destination — The destination is determined by translation in the E164 numbering plan. The NOA must be Unkown and the digits to be translated in the E164 numbering plan should comply with the E164 plan. The output of translation is fed to the E.164 translation tables defined via Global Numbering Plan section of Lotus Sametime Unified Telephony Assistant
Invalid Code — Points to an invalid dialed number. Only available for prefixType Attendant.
The digit position at which to continue further digit translation of the dialed number. A list of Destination Names/Services/Announcements is shown.
If destination type is Destination, the destination name must point to a generic destination created in the system. The call is routed using the routes assigned to the destination.
If destination type is Service, the destinaton name must point to pre-defined service name. Internally XLA stores the values as Undefined or the service Id. The digits are translated by XLA into service Id and return to calling component which starts the service if the calling party is allowed to invoke the service.
If destination type is Invalid Code, the destination name can be UNDEFINED or point to a intercept in the intercept table. The call is sent to the intercept treatment
It is strongly recommended to have all default service access codes in the GNP and override them in the PNP if they need to be different for the users of that PNP.
