scope:

The present document describes how the H.323 protocol suite can be used to implement the architecture, defined in TS 101 314 [8] and the primitives, information elements and behaviours, defined in TS 101 882.

The present document defines the mapping of the following meta-protocols:

• the Registration meta-protocol;

• the Bearer Control meta-protocol; and

• the Call Control meta-protocol.

The document is applicable to equipment performing the roles of terminal, gateway, gatekeeper and also to entities within the IP network that are necessary to support TIPHON Release 3.

The H.323 profile contained in the present document was derived by examination of:

• ITU-T Recommendation H.323 [10] and associated suite of protocols:

- H.225.0 (RAS and Q.931); and

- H.245 (Media control channel-signalling protocol);

• the capabilities required by TS 101 878 [6] for the support of TIPHON as identified in TR 101 300 [4];

• the TIPHON baseline architecture described in TS 101 314 [8];

• the primitives, parametrs and the procedures defined in TS 101 882.

Where the text indicates the status of a requirement (i.e. as strict command or prohibition, as authorizations leaving freedom or as a capability or possibility), this may modify the nature of a requirement within a referenced standard used to provide the capability.
