The normalization feature normalizes telephone numbers from local to national format and from national to international format.
This normalization can take place at the PAC (Prefix Access Code) table level or at the Destination Code level.
If a normalization is performed at the Destination Code level, it is accomplished by a generic code processing mechanism that provides the capability to modify the called party number and its nature of address after translation.
This feature requires that a code processing destination type is defined. The selected entry in the code processing table does the following:
Defines a rule for modifying the dialed number (delete and add digits) and changing the NOA (Nature of Address) before the next routing step.
Gives the option to retranslate the number, which causes the system to use the modified number on a new pass through the Global Number Code table or go to a specified destination of a different type.
The following are examples of the normalization:
A number dialed without a LAC (Local Area Code) can be normalized to a national number. For example, a subscriber number of 72212345 can be normalized to 8972212345, where 89 is the LAC.Parent topic: Numbering Plan
A number dialed without an LAC can be normalized to an international number. For example, a subscriber number of 72212345 can be normalized to 49 8972212345, where 49 is the Country Code (CC) and 89 is the LAC.
A number dialed with an LAC can be normalized to an international number. For example, a subscriber number of 89 72212345 can be normalized to 49 8972212345, where 49 is the CC and 89 is the LAC.
