10.7 TELECOMMUNICATION STANDARDS

In telecommunication system design, the standards play a very important role. The days when organizations used to develop proprietary interfaces and protocols are gone. Before embarking on a system design, the designer has to look at international/national standards for the interfaces and protocols. The various standards bodies for telecommunication/data communications are:

• American National Standards Institute (ANSI)

• Electronics Industries Association (EIA)

• European Telecommunications Standards Institute (ETSI)

• Internet Engineering Task Force (IETF)

• International Organization for Standardization (ISO)

• International Telecommunications Union Telecommunications Services Sector (ITU-T), earlier known as CCITT

• Institute of Electrical and Electronics Engineers (IEEE)

Throughout this book, we will mention a number of relevant standards related to telecommunication systems and interfaces as well as communication protocols. Referring to the standards documents is very important to get an in-depth knowledge of the specifications, particularly during implementation.

Nowadays, communication system design is driven by international standards. The standards formulated by standardization bodies such as ANSI, EIA, ETSI, IETF, ISO, ITU-T and IEEE need to be followed while designing communication systems and protocols.
