2. 2. 7 Separate Regional Prefix Category
Tab. 10 Category for separate regional prefix in the internal numbering plan
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 type = pri-
vate
If the first few digits match up with the PINX's own regional prefix, they will be trun-
cated.. The remaining number is then analysed and forwarded
