The authors propose and evaluate 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 or multiplexers using distributive demand assigned TDMA (time division multiple access). Within each group time slots are shared between voice and data users through a movable boundary. Since voice has real-time constraint, it is given higher priority in the use of channel resource. Blocked calls are assumed lost. Mathematical expressions for several key performance measures are derived. Numerical examples are used to demonstrate the performance of this protocol, and the results presented from computer simulations verify the performance.<<ETX>>
