    Abstract
    Integrated Services Digital Network (ISDN) is an extension of conventional telecommunications and the data trafics like text, facsimile, image. Efficient transmission of voice/data on a common communication channel has attracted a lot of attention in the area of digital communication. To achieve integrated communication, many techniques have been proposed, studied and applied in various fieltls, especially in multimedia communications. In this thesis, a new technique of voice/data integration using movable boundary concept for optimum channel utilization has been proposed. The performance evaluation of dynamic channel allocation between voice and data trafic is carried out using analytical, simulation and experimental methods. An interface circuit has bcen developed to dynamically allocate slots between voice and data. This is realized by generating the control signals based on the status of each voice station. A Dynamic Slot Selector for allocating the slots between voice and data has been implemented. A scheme is also proposed to allocate priority to voice over data and to utilize the inactive voice slots by data trafic. Simulation studies have been carried out based on the analytical methods and the results are verified by the hardware experimentation for slot allotment between voice and data trafic. The channel ulilization is measured for data and voice independently, and together. Simulation work is also carried out to study the throughput by varying the number of active voice stations.
