Separate regional pre-
fix
This regional prefix allocates a PINX to a PISN region.
The PINX compares its own regional prefix entry with the first few digits of the call
numbers of the following calls:
• All outgoing calls
• All incoming calls routed via a trunk group with the setting "Network=private"
If the first few digits match up with the PINX's own regional prefix, they will be
truncated. The remaining number is then analysed and forwarded.
