scope:

The following aspects of the relationship between IP networks and telecommunication networks are included:

1) access to IP networks using telecommunication facilities;

2) interworking between IP networks and telecommunication networks (e.g. gateway functions between IP and other protocols on layer 3);

3) transport mechanisms for IP networks (e.g. IP over other protocols).

The following aspects, which are within the scope of the ITU-T work, are not included:

1) application interworking;

2) the integrated use of signalling in IP as well as traditional networks;

3) analysis of future IP protocols;

4) access techniques for telecommunication networks.

NOTE: The ETSI project TIPHON is the lead body for Multimedia over IP.
