Welcome to the Copper/Optical Access, Synchronization and Transport Committee (COAST)

Special Notice and Information:

The first meeting of the ATIS COAST Committee took place in April 2010 at the ATIS Annual Meeting of the Committees (AMOC). The COAST Committee develops and recommends standards and technical reports for home, access, and transport network and synchronization technologies over copper and optical mediums. The COAST Committee is comprised of four subcommittees: COAST Network Access Interfaces (NAI), COAST Optical Access Networks (OAN), COAST Optical Hierarchical Interfaces (OHI), and COAST Synchronization (SYNC). These subcommittees were formerly a part of the Optical Transport and Synchronization (OPTXS) and Network Interface, Power, and Protection (NIPP) Committees.

The creation of the COAST Committee was suggested by Committee leaders and accepted by the ATIS Board of Directors in 2009 to improve productivity and efficiency in standards development for tomorrow's converged next generation networks.

2010 contributions for NAI, OAN, OHI, and SYNC can be found in the contribution database by searching for COAST NAI, COAST OAN, COAST OHI, and COAST SYNC.

 
--Mission-
- --


The Copper/Optical Access, Synchronization and Transport (COAST) Committee engages industry expertise to develop and recommend standards and technical reports for home, access and transport network and synchronization technologies over copper and optical mediums. COAST is committed to proactive engagement with national, regional and international standards development organizations and forums that share its scope of work.

--Scope-
- -

The technical requirements, measurement techniques, metrics, and operational practices documented in COAST’s work products encompass copper and optical network interfaces and transceiver functionality required for access to, and transport through, telecommunications networks. The work includes, but is not limited to:

  • the electrical, electromagnetic, optical, and mechanical characteristics of interfaces;
  • the physical layer transmission and signaling protocols;
  • hierarchical optical structures;
  • network synchronization interfaces;
  • wired home networking transceivers;
  • review & vetting of US member company contributions to ITU-T SG 15.
