ITU-T Study Group 15 Area of Responsibility (Study Period 1997 - 2000)
Study Group 15 shall develop and maintain Recommendations on:
  • transport related aspects of networks (including the signal processing aspects of network echo control), taking into account the general network concept and network performance objectives set by other Study Groups
  • systems and equipment for transport networks (e.g. SDH/ATM multiplexing, cross-connect and switching equipment, muldexes and statistical muldexes  for data applications);
  • line transmission systems and equipment for access network and core network applications on optical and metallic media;
  • application of TMN to facilitate the management of transport networks, systems and equipment in accordance with the general TMN concept set up by Study Group 4;
  • implementation of SDH and PDH digital hierarchies (e.g. bit rates, interfaces, multiplexing structure, etc.);
  • transmission techniques and associated implementation topologies for the local loop and access environments (e.g. PON, photonic network, etc.);
  • coordination and harmonization of the ITU-T work on access network transport (Lead Study Group).
