Part 2 Numbering Plan 175
2.2.5 Separate Regional Prefix Category
Tab. 2.8: 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 = 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
2.2.6 Shared Numbering Plan
PISN subscribers are structured in the internal numbering plans of the PINX.
From the PINX's viewpoint its own subscribers are internal subscribers and the
subscribers of the other PINXs are PISN subscribers..
If two or more PINXs are structured in such a way that they split the range of sub-
scriber numbers among themselves, we talk of a shared numbering plan.
Together they form a region, within which all subscribers can be reached under
the internal call number.
