Abstract

Rapid technological developments in the field of computers and telecommunications in the last 50 years have led to their convergence for information processing and transmission. Further, during the last decade, there has been reduction in the cost of equipments and transmission systems resulting in their wide spread availability and deployment. Moreover, there has been proliferation in the variety of service demands by the customers in the recent years. As the core telecommunication networks mature with the variety of switching and transmission systems, selection of appropriate technology for accessing the core network by the end users for multiple services at appropriate cost and QoS becomes a major issue. With the predominance of EPABX/LANs at the customer premises, access networks are becoming more demanding in terms of higher bandwidth to satisfy the application needs. In addition, traditional circuit switched based applications are migrating to packet switched technology for better channel utilization. The selection of appropriate access technology becomes more complex due to variety in regulations across countries, service providers offering new services and heterogeneous access channel environment (fixed, mobile, satellite etc) available to the user. Since no single technology is suitable for all the applications, knowledge of various access technologies, QoS demands of various services, cost and market trends are important before making long term investments. Panoramic view of these topics will be presented in the seminar.
