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.

Working groups in ETSI TM
WG TM1 Core networks, fibres and cablesWG TM4 Fixed radio systems WG TM6 Access network
Network Standardisation
The aim of ETSI TM is to standardize the functionality and performance of transport networks and their elements. Transport networks include everything necessary to provide digital paths between end users and switching nodes.

http://www.etsi.org/TMETSI 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).
Network aspects are standardized by ETSI SPAN (Services and Protocols for Advanced Networks).
