  • Responsible for studies concerning data communications, data networks
    and open system communications
  • Study Group 7 is to take the primary role for developing Recommendations in the following areas:
  • open systems interconnection (X.200-, X.600-Series, etc.);
  • message handling services and systems (F.400- and X.400-Series);
  • directory services and systems (F.500- and X.500-Series);
  • security, including frameworks, mechanisms and protocols (X.800-Series);

  • packet and frame relay, including interworking cases for data  communications;
  • highly reliable (loss sensitive or assured) U-plane data communications protocols over ATM (e.g. X.25, X.45 or other OSI protocols over ATM), including interworking.

In addition, Study Group 7 is the Lead Study Group for:
  • open distributed processing (ODP);
  • frame relay;
  • communication systems security
  • With regard to GII and multimedia, Study Group 7 is responsible for detailed services and protocols in all of the above listed areas and from the viewpoint of data communications. Direction on what studies need to be undertaken in support of GII and multimedia will come from Study Group 13 and Study Group 16, respectively.

With regard to numbering, routing and network performance:
  • Numbering, routing: Study Group 2 is responsible for general principles for numbering and routing applicable to all networks. Study Group 7 is responsible for detailed work on numbering and routing for public data networks, including Recommendations X.110, X.121, X.122 and X.353.Ongoing work is to take into account Recommendations on general principles established by Study Group 2.
