ETSI

Network Standardisation

http://www.etsi.org/

The European Telecommunications Standards Institute (ETSI) is a non-profit making

organization whose mission is to determine and produce the telecommunications standards that will be used for decades to come.

It is an open forum that unites 696 members from 50 countries, representing Administrations, network operators, manufacturers, service providers, and users.

Any European organization proving an interest in promoting European telecommunications standards has the right to represent that interest in ETSI and thus to directly influence the standards making process.

ETSI TM Transmission and Multiplexing

Work areas for ETSI TM:

- optical fibre cables and components - line systems and multiplexers

- cross connection equipment

- end to end performance aspects, including network protection - fixed radio systems

- digital subscriber line systems for metallic cables

Network management aspects are standardized by ETSI TMN (Telecommunications Management Network).
