Standards allow things to be trusted !!  They allow things to work together with one another.  Without standards, we could not count on anything in this world.  

The number of standards groups (called "bodies") is staggering.  Why, in the U.S. alone, it is estimated that there are hundreds of “traditional” SDO's (Standards Developing Organizations).  The 20 largest SDOs produce 90% of the standards - and hundreds more “non-traditional” standards development bodies, such as consortia, pitch in with their own sets of standards. 

There are literally millions of standards, which form the basis of product development.  Standards are recorded and published for the world, so that products can be designed with interoperability in mind.  The only way to be sure that a design will coexist with other systems, is to have a standard to follow.  These pages discuss the most prevalent telecom standards as well a electrical and mechanical standards.

Working Together - this is the biggest challenge that faces the standards groups.  If they all developed standards on theor own for the same technology (and this happens constantly) without deferring to the others, chaos would result.  For example, you would have 20 differing standards on SONET.  They must maintain close contact with one another and work together.  The key is communication, cooperation, and partnering.  For example, ANSI oversees hundreds of standards bodies to make sure that they do not all work on the same thing.  Then it updates it's published standards if another standards organization, such as ISO, makes a parallel yet new change to that particular technology.

http://www.iso.org  (you can buy ISO standards at http://www.iso.org/iso/en/prods-services/ISOstore/store.html ).  ISO (International Organization for Standardization) is the world's largest developer of standards - principally in the development of technical standards.  Their most famous standard, oddly enough, goes by the acronym "OSI" - the reverse of ISO.  Short for Open System Interconnection, OSI is  ISO standard for worldwide communications that defines a networking framework for implementing protocols in seven layers.

ISO is a non-governmental organization whose network of the national standards institutes includes 148 countries, with a Central Secretariat in Geneva, Switzerland, that coordinates the system.  Many of their standards were developed in concert with the IEC and are named as such - for example, ISO/IEC 23290:2004 - still others were published by ANSI, for example:  ISO/IEC 15521:1998.

  International Telecommunication Union

 - http://www.itu.int/home/index.html - The ITU, headquartered in Geneva, Switzerland is an international organization within the United Nations System where governments and the private sector coordinate global telecom networks and services.  There are three types of ITU standards:

NOTE:  the ITU lists all prices for it's standards in "CHF", which is "Swiss Francs" - you can use this currency converterfrom XE.com.  At this time (March 2005,  1 CHF = 85 cents ($0.85)

ITU-R  -  Radio (radio communication) - this division of the ITU has published critical standards such as the entire Frequency Spectrum assignments.  The ITU-R Recommendations can be purchased on CDROM at http://www.itu.int/publications/main_publ/itur.html .  Additionally many of the smaller sets of ITU-R documents can be purchased at http://www.itu.int/publibase/catalog/itupub.asp?Part=3.3 

ITU-T  -  Telecom (telecom standardization) - created on 1 March 1993, the ITU-T replaced the former CCITT (International Telegraph and Telephone Consultative Committee) whose origins go back to 1865.  The entire set of ITU-T publications can be purchased on DVD at http://www.itu.int/publications/main_publ/itut.html 

ITU-D  -  Development  (telecom development) - rarely used by anyone, so we will not cover these standards here

SERIES OF ITU-T RECOMMENDATIONS

The CCITT and the subsequent ITU-T used letters to denote a number of "series", or categories of standards.  You will often see these standards listed with a period after the letter of the series.  For example, X.25 is a packet data communication protocol, and is from the "X series" (Data networks and open system communications), and V.32 is a modem standard from the "V series" (Data communication over the telephone network), etc

 

Corrigendum - many recommendations later are corrected or modified.  This is called "erratum" by IEEE with their RFC's.  But the ITU calls it "corrigendum".

 

A series - Organization of the work of ITU-T

B series - Means of expression: definitions, symbols, classification

C series - General telecommunication statistics

D series - General tariff principles

E series - Overall network operation, telephone service, service operation and human factors

F series - Non-telephone telecommunication services

G series - Transmission systems and media, digital systems and networks

H series - Audiovisual and multimedia systems

I series  -Integrated services digital network

J series - Transmission of television, sound programme and other multimedia signals

K series - Protection against interference

L series - Construction, installation and protection of cables and other elements of outside plant

M series - TMN and network maintenance: international transmission systems, telephone circuits, telegraphy, facsimile and leased circuits

N series - Maintenance: international sound programme and television transmission circuits

O series - Specifications of measuring equipment

P series - Telephone transmission quality, telephone installations, local line networks

Q series - Switching and signalling

R series - Telegraph transmission

S series - Telegraph services terminal equipment

T series - Terminals for telematic services

U series - Telegraph switching

V series - Data communication over the telephone network

X series - Data networks and open system communications

Y series - Global information infrastructure and Internet protocol aspects

Z series - Languages and general software aspects for telecommunication systems

 

CCITT (International Telegraph and Telephone Consultative Committee) well-known Standards

Before becoming the ITU-T, the CCITT developed many standards and many of them are still referenced as "CCITT" standards.  The more well-known CCITT standards, now adopted by the ITU-T, are the V. and X. standards, such as:

  • V.21: The standard for full-duplex communication at 300 baud in Japan and Europe. In the United States, Bell 103 is used in place of V.21.
  • V.22 : The standard for half-duplex communication at 1,200 bps in Japan and Europe. In the United States, the protocol defined by Bell 212A is more common.
  • V.22bis : The worldwide standard for full-duplex modems sending and receiving data across telephone lines at 1,200 or 2,400 bps.
  • V.29: The standard for half-duplex modems sending and receiving data across telephone lines at 1,200, 2,400, 4,800, or 9,600 bps. This is the protocol used by fax modems.
  • V.32 : The standard for full-duplex modems sending and receiving data across phone lines at 4,800 or 9,600 bps. V.32 modems automatically adjust their transmission speeds based on the quality of the lines.
  • V.32bis: The V.32 protocol extended to speeds of 7,200, 12,000, and 14,400 bps.
  • V.34 : The standard for full-duplex modems sending and receiving data across phone lines at up to 28,800 bps. V.34 modems automatically adjust their transmission speeds based on the quality of the lines.
  • V.42 : An error-detection standard for high-speed modems. V.42 can be used with digital telephone networks. See MNP for a competing standard.
  • V.42bis: A data compression protocol that can enable modems to achieve a data transfer rate of 34,000 bps.
  • V.90: The standard for full-duplex modems sending and receiving data across phone lines at up to 56,600 bps.
  • X.25: The most popular packet-switching protocol for WANs.
  • X.400: The universal protocol for e-mail. X.400 defines the envelope for e-mail messages so all messages conform to a standard format.
  • X.500: An extension to X.400 that defines addressing formats so all e-mail systems can be linked together.

    If you remember anything from these pages - remember ANSI !!!  The ANSI Federation of is made up of nearly 1,000 U.S. businesses, professional societies and trade associations, standards developers, government agencies, institutes and consumer and labor interests.   It accredits qualified organizations, whose standards development process meets all of ANSI’s requirements, to develop American National Standards.  ANSI is not a government agency.

    ANSI only publishes standards from other organizations - it does not develop standards on its own ! ! !  

    ANSI does 2 things: - it accredits standards groups, and it publishes the standards created by those groups.

    Conformity Assessment - All standards published by ANSI must first pass Conformity assessment, which is defined as any activity concerned with determining directly or indirectly that relevant requirements are fulfilled. (As defined in ISO/IEC Guide 2:1996)

    ANSI is the standards body of standards bodies.  It is the group that makes sure the standards bodies are  .  .  .  well, standard  !!  It is an overseer of standards bodies.  ANSI is a private, non-profit organization - [ tax exempt via IRS code (501(c)3) ] that administers and coordinates the U.S. voluntary standardization and conformity assessment system.  ANSI facilitates the development of American National Standards (ANS) by accrediting the procedures of standards developing organizations (SDOs).  In order to maintain ANSI accreditation, standards developers are required to consistently adhere to a set of requirements or procedures known as the “ANSI Essential Requirements," that govern the consensus development process.

    ANSI also is a publisher of thousands of standards - when a standard is created by a standards developer who works under the ANSI umbrella - it becomes an "ANSI Standard".  There are three naming conventions for these standards is as follows - some include the acronym, "ANSI", while others do not:

    • ANSI/organization standard_number

    • ANSI standard_number

    • organization standard_number

    Examples:

    • ANSI C136.23-1995  -  an IEEE standard published by ANSI

    • ANSI/IEEE C2-2002  -  an IEEE standard published by ANSI

    • UL 38-2001  -  an Underwriters Laboratories standard published by ANSI

    ANS (American National Standards) -  provide dimensions, ratings, terminology and symbols, test methods, and performance and safety requirements for personnel, products, systems and services in hundreds of industries.  Many ANS documents make it clear how to improve the safety of products for the protection of consumers, including products such as baby cribs, bicycle helmets, home appliances, lawn mowers, ladders, etc.  The ANS's are essential tools used in every industry. Today, there are more than 11,500 American National Standards that have been developed and approved in accordance with ANSI Procedures.

    ANSI as a U.S. Representative to the International Standards Communities

    ANSI is the official U.S. representative to the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) via the U.S. National Committee (USNC).

    Q: Does ANSI develop the U.S. position on ISO and IEC standards?

    A: Yes and No. ANSI and its U.S. National Committee for the IEC (USNC) help to govern both organizations by serving on their respective governance bodies. ANSI accredits and the USNC approves U.S. Technical Advisory Groups (U.S. TAGs) to develop and transmit, via ANSI or the U.S. National Committee, U.S. positions on activities and ballots of the international technical committee.

    The U.S. also helps to facilitate and direct the technical work by holding leadership positions on 30 ISO Technical Committees (TC), more than 100 Subcommittees (SC) and nearly 500 working groups. The U.S. holds leadership positions in nearly 40 IEC TCs and SCs, and is actively involved in more than 175 of its other committees.

    ANSI/TIA Standards

    This site http://cablingdb.com is fantastic because it carries all the ANSI/TIA standards for free, and has the documents in their entirety !!!  Here are the main categories of the standards they carry:

    Cabling Glossary of Terms

    ANSI/TIA/EIA 568-B  (twisted pair cabling, fiber, and the now famous Cat3, Cat5e and Cat6 cabling standards)

    ANSI/TIA/EIA 569 Pathways & Spaces

    ANSI/TIA/EIA 570-A Residential Telecommunications

    ANSI/TIA/EIA 598-A Fiber Optic Color Coding

    ANSI/TIA/EIA 606 Administration

    ANSI/TIA/EIA 607 Grounding & Bonding

    ANSI/TIA/EIA 758 Customer Owned Outside Plant

     

    Interface Standards

    Many standards primarily include "interfaces", since that is the point where systems communicate.  For example, the RS-232 standard discusses the way in which an external modem or other device, interfaces with a 9-pin (typically) serial port on a PC.  The mode itself can be designed in many ways, so long as it's communication to the outside world strictly follows the RS-232 standard.

    Here are the typical telecom standards that providers use to connect customers to their Networks.  Of course, these are only typical, and the actual number of standards is diverse :

    Speed   

    Typical Interface

    DS0   

    Twisted Pair (POTS)

    T1, fract T1   

    V.35

    T3, fract T3   

    HSSI

    T3 HSSI or Coax BNC

    OC3 and up   

    Fiber ST, SC, etc.

    Project 802

    Project 802 was developed in order to produce standards for local and metropolitan area networks. The 802 standards are aimed at the Physical Layer of the 7 layer OSI model.

    One of the main driving forces behind 802 was to have interoperability between hardware manufacturers and software producers, thus giving potential customers full choice in the products and software they purchase.

    While there are many 802 projects and sub workgroups, the major projects are noted below.

    IEEE 802.3-Carrier Sense Multiple Access with Collision Detection (CSMA/CD)

    This group is concerned with Physical and Data Link layer standards for LANs which use CSMA/CD access method and a bus topology. Examples of these LANs are Ethernet, Fast Ethernet and Gigabit Ethernet.
