INTEGRATED SERVICES DIGITAL NETWORK (ISDN): FEATURES AND SERVICES

Integrated Services Digital Network (ISDN) technology is one of the important developments held in the field of telecommunication. It is most powerful tool for various services such as voice, images, and video and multimedia data communication over the telephone network. ISDN may be viewed as a logical extension to the digitalization of telephone network and has become very common in the western countries. The most fascinating fact about ISDN is that it is related to information and the integration of data, text, picture and voice. ISDN uses the existing local telephone wiring and is equally available to home and business customers. ISDN services are being offered at a premium today.

Implementing ISDN: A Sociotechnical Analysis

1988

This sociotechnical analysis assesses the effects on the educational environment of migrating from the currently fragmented analog system to an environment dominated by integrated digital telecommunications systems. An integrated telecommunications channel is at the heart of the design for an ISDN (integrated services digital network). ISDN is a set of technical standards and a network architecture that describe a digital telecommunications channel able to carry voice, data, and compressed video on the same telecommunications network. Two central issues are how an integrated telecommunications system will differentially affect voice, data, and video users, and whether ISDN inherently favors large or small "customers" for telecommunications services. The conceptual discussion is followed by a case study of a large university (Ohio State) in the process of developing an integrated telecommunications system. (26 references) (Author/EW)

Service provisioning data relationship model for ISDN network maintenance

Selected Areas in Communications, IEEE Journal on, 1988

In today's POTS-oriented telephone network, the data required for trouble-shooting are generally rather simply related because one service usually has one directory number, rides alone on a unique facility, and has one termination on the switch. The ISDN architecture introduces, as a norm, service capabilities and configurations with multiple facility and equipment assignments, directory numbers, and terminals. If ISDN is to be the telecommunications architecture for the 1990's, the operating companies that provide it must be prepared to support their customers with maintenance and trouble-shooting capabilities equal to dealing with the complexity of the service offerings. In this paper, I propose data relationship models to organize service provisioning data to support network maintenance of the ISDN. In particular, I propose a hierarchical database model to support Primary Rate Interface, but a relational database structure to support Basic Rate Interface.

ISDN standardization

Proceedings of the IEEE, 1991

sions of ISDN standardization are briejly explained. Sadahiko Kano (Member, IEEE) received the B.E., M.Sc , and Ph.D. degrees in electrical engineenng from the Universlty of Tokyo in 1967, from the University of Essex in England in 1974, and from the University of Tokyo in 1979, respectively.

Harmonised Internet and PSTN service provisioning

Computer Communications, 2000

The current situation of telecommunications is characterised by the presence of multiple networks, each providing its own services. The original idea of a fully integrated network, which was originally introduced with ISDN and further propelled by the B-ISDN concept, seems unlikely to be realised at a complete extent. However, unification needs between different networks are present, an example being voice/data integration. Bringing together the characteristics of different networks creates a huge potential for new services, which can take advantage of strong points of individual networks in order to optimise specific service parameters. However, although network integration at transport technologies may be an idealistic assumption, the management of services traversing different networks cannot be done without considering the accurate definition of a unified service framework, taking care of harmonising, from a service designer's viewpoint, differences existing at network transport layers. In other words, if transport integration cannot be achieved, integration at service design and service management level must be pursued in order to cope with emerging and future services. Mobile Agent Technology (MAT) based on Distributed Object Technology (DOT) represents a key issue in defining methodologies and framework for a unified service environment encompassing different networks. These technologies, being largely independent from the underlying network, provide the means to build and manage services in a heterogeneous environment. Furthermore, they allow an easy deployment of new components on network systems, which is a key requirement in facing the problem of providing services in a fast and efficient way in a rapidly changing environment. This paper discusses a DOT/MAT based approach to the problem of creating and managing services in a heterogeneous network environment. ᭧
