Modeling telecommunications networks' transmission systems

IEEE Communications Magazine, 1996
The author discusses the status of synchronous digital hierarchy (SDH) management standards and related matters such as plesiochronous digital hierarchy (PDH), and offers an overview of the information contained within these standards. He provides an overview of those areas that are still under study or need further investigation by international ...

Telecommunications for HVDC Transmission

IEEE Transactions on Power Apparatus and Systems, 1968
The control and operational principles of HVDC transmission are briefly reviewed. Basically no telecommunication is necessary for operation, with the exception of telephone connections. As the demand for service and system control increases, telecommunication requirements will grow. General requirements of telecommunications are summarized and specific

Soliton transmission in telecommunication networks

IEEE Communications Magazine, 1994
Erbium-doped fiber amplifiers are a major breakthrough for soliton communication. Most of the difficult problems preventing soliton communication recently were solved using erbium-doped optical fiber amplifiers (EDFAs). Progress in optical soliton communication has been very rapid, since the invention of the 1.48 /spl mu/m laser diode pumped EDFA ...

Document Image Transmission by Telecommunication

Journal of Forensic Sciences, 1990
Abstract Photophone® is an image-transmission device which uses telecommunications to transmit questioned documents for examination on an international scale. This instrument, now in use by the Department of Justice, Immigration and Naturalization Service (INS), is a combination video camera and monitor screen, high-power microscope ...

Alternative transmission modes for telecommunications networks

The Annals of Regional Science, 2000
Since the introduction of competition in the telecommunications sector, private firms have been facing new possible choices concerning their telecommunications systems. To evaluate these possibilities the traditional microeconomic production theory proves to be helpful.

Convergence of voice and data telecommunications transmissions

INTELEC. Twenty-Second International Telecommunications Energy Conference (Cat. No.00CH37131), 2002
Our insatiable need for instant information will continue to make telecommunication systems an increasingly integral part of our society, demanding ever more services for real-time data and, of course, reliable networks. Mobility in society is key today, and the ability to be "always connected" is crucial not only to business people, but to the general

Telecommunications and data transmission

1992
The term ‘telecommunications’ is used to describe all the methods which transmit information electronically. In the UK, the national telecommunications network is supplied by British Telecom. However, other companies are now providing and competing for specialised services. For example, Mercury has established some networks and services.

Future trends in digital telecommunication transmission networks

Electronics & Communication Engineering Journal, 1990
New technology is needed by digital transmission networks for the increased bandwidth, performance and reliability requirements of existing and future telecommunication services, such as broadband ISDN. Increased flexibility, automation and control are also major issues being addressed.

Evolution scenarios for optical telecommunication networks using multiwavelength transmission

Proceedings of the IEEE, 1993
The authors discuss how the transition in telecommunication networks taking place with increasing use of fiber in all segments of the networks, together with the increasing demand for broadband services, will lead to new network architectures. The customer access portion of these networks may have a large geographical range and high functionality, and ...
