Abstract
In an integrated telecommunications system both voice and data compete for use of the same group of channels. Such a system allows for better use of the channels and more efficient use of the system facilities. Numerous operating rules for allowing voice and data access to the channels can be considered. In this paper, we give a steady state queueing analysis for two priority rules, voice pre-empting data and data pre-empting voice, when the mean service times of voice and data are different.
