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.
