A Flexible Numbering Plan (FNP) allows the length of Location Codes
(LOCs) to vary from node to node. As well, the total number of digits dialed
to reach a station can vary from station to station. It also allows flexibility for
the length of the location codes from node to node. An FNP can be used to
support country-specific dialing plans. FNP also allows users to dial numbers
of varying lengths to terminate at a destination. Flexibility of the number of
digits which can be dialed is achieved using Special Numbers (SPNs).
IP Trunk 3.01 (and later) and ITG Trunk 2.x support a mixed network of
remote nodes with ESN5 and standard (that is, non-network) signaling. ESN5
is an extension of MCDN signaling which can be used by IP Trunk 3.01 (and
later), ITG Trunk 2.x, and IP Peer (CS 1000S and CS 1000M).
