Integrated voice/data transmission in a high speed common channel using demand assigned movable‐boundary TDMA multiplexer

Abstract

The paper proposes and evaluates a protocol which combines the ideas of demand assignment and movable boundary for integrating voice and data traffic in a high speed common channel. Each multiplexer serves a group of voice users plus a data user The common channel is shared by a number of groups of multiplexers using distributive demand assigned TDMA. Within each group time slots are shared between voice and data users through movable boundary Since voice has real‐time constraint, it is given higher priority in the use of channel resource. Blocked calls are assumed lost. In this paper, mathemetical expressions of several key performance measures are derived. Numerical examples are used to demonstrate the performance of this protocol and computer simulations are also conducted to verify the results.

Key words:

• movable boundary
• demand assignment
• reservation
