The output of QAM transmitter firstly passes through 32 kb/s ADPCM codec [the detail of ADPCM codec is found in (CCITT
Recommendation G.721, 1984)].
The next 100 pages are devoted to detailed accounts of three technological standards which were considered by the CCITT
. The last forty pages integrate the theory of actor-centered institutionalism with the case study.
Till the 1970s, standard-setting in international telecommunications was monopolized by the CCITT
, a sub-unit of the International Telecommunication Union (ITU), the UN special agency for telecommunications.
The Consultative Committee on International Telephony and Telegraphy (CCITT
), organized by the United Nations, has generated international communications recommendations which are frequently adopted as standards.
The resolution is limited to th fine mode standard defined for CCITT
Group 3 FAX machines.
Document Image Standard: A technical standard describing the digital format of a print/display file of a report or other document (for example, CCITT
(Consultative Committee on International Telegraphy and Telephony) X.25 recommendation is an interface standard for the connection of terminals and computers for public data networks.
In 1984 the International Telegraph and Telephone Consultative Committee of the International Telecommunications Union (ITU CCITT
) issued the "X.400" recommendations, a set of standards defining the way in which electronic mail could be addressed, stored, transmitted and retrieved from a network.
defines ISDN as a network evolved from the telephony integrated digital network (IDN) that provides end-to-end digital connectivity to support a wide variety of services to which users have access through a limited set of standard multipurpose customer interfaces.
The system has been designed to meet NATO standards, but with its modular interfaces and protocols for open systems it is also in full accordance with ISO, CCITT
and IEEE standards.
