3. 2. 9 PISN with different Regions
A PISN can be divided into several regions. Each region is identified by its regional
prefix.
Users who call a user in a different region first dial the prefix of the destination region,
then the internal number of the user they want.
Their specific regional prefix is specified in the internal numbering plan ( =g4) of each
PINX.
The organization of the numbering plan does not depend on the PISN topology.

Entering a Regional Prefix
In the example above the PISN users of a different region are entered with the regional
prefix (for example 60200 to 60299)
Another possibility is to define a route with call number 60 and to enter the PISN users
without regional prefix (route method).
The user dials exactly the same number, for example 60250, but this time the call is
routed as a route selection. It uses the route with call number 60 and not the one allo-
cated to the PISN user in the user configuration. (In the example above the numbers
would have to be distributed differently since number ranges cannot be assigned
twice.)
