microwave transmission equipment
To allow the usage of microwave transmission equipment, all European and many
non-European national authorities require that the equipment must meet the ETSI
standards.
ETSI standards are published in different series. Here are two examples; EN
302 217 and EN 300 019.
Series EN 302 217 is the main standard for point to point microwave transmission
equipment. It consists currently of six different publications and states technical
specifications for radio equipment and antennas.
Series EN 300 019 is a more generic standard for electronic equipment which
specifies under what environmental conditions the equipment shall be
operational. This is specified for equipment intended for indoor and outdoor use
and in operation, storage and transportation.
ETSI standards are available for download from the ETSI web site, etsi.org.
There are several additional standardization institutes which are relevant to telecommunications
equipment.
ITU-T, the Telecommunication sector of the ITU, issues recommendations for nearly every
aspect of telecommunication. The given example, ITU-T recommendation G 703, is the
electrical specification for PDH, SDH and Sonet interfaces which are very common in
Microwave equipment.
However, most new microwave deployments are now for Ethernet traffic. Ethernet interfaces
and traffic handling is specified by the Institute of Electrical and Electronics Engineers IEEE (“I
triple E”). I triple E recommendations 802.3 are examples of standards which are fundamental
for Ethernet technology
Internet Protocols are widely used for management of microwave networks. Protocols and
standards for Internet traffic are specified in so called Request for Comments, RFC, from the
Internet Engineering Task Force, IETF. An example of an IETF standard is the RFC 791 which
is basic for data communication over the Internet.
A perhaps somewhat simplified way to summarize is that ITU-T specifies TDM traffic and
interfaces, IEEE Ethernet Layer 2 interfaces and traffic and the IETF IP Layer 3 Internet
Protocol.
The International Electrotechnical Commission IEC is a standardization body which specifies
equipment building practice and electrical safety requirements.
Requirements for equipment enclosures are for example standardized in recommendation EN
60 950-1
