Description: Call signalling protocols and media stream packetization for packet-based multimedia communication systems, International Telecommunications Union (ITU) Telecommunication Standardization Sector (ITU-T) Recommendation H.225, covers the technical requirements for narrow-band visual telephone services defined in ITU-T H.200 and F.720-series Recommendations, in those situations where the transmission path includes one or more packet-based networks, each of which is configured and managed to provide a non-guaranteed Quality of Service (QoS), which is not equivalent to that of Narrowband - Integrated Services Digital Network (N-ISDN), such that additional protection or recovery mechanisms beyond those mandated by ITU-T Rec. H.320 need be provided in the terminals. It is noted that ITU-T Rec. H.322 addresses the use of some other Local Area Networks (LANs) which are able to provide the underlying performance not assumed by the ITU-T Recs H.323 and H.225.0.
Technology/Standard Usage Requirements: Users must ensure their use of this technology/standard is consistent with VA policies and standards, including, but not limited to, VA Handbooks 6102 and 6500; VA Directives 6004, 6513, and 6517; and National Institute of Standards and Technology (NIST) standards, including Federal Information Processing Standards (FIPS). Users must ensure sensitive data is properly protected in compliance with all VA regulations. Prior to use of this technology, users should check with their supervisor, Information Security Officer (ISO), Facility Chief Information Officer (CIO), or local Office of Information and Technology (OI&T) representative to ensure that all actions are consistent with current VA policies and procedures prior to implementation.
