Abstract: This paper proposes and studies the performance of a wideband bit-rate compression and restricted access traffic control strategy suitable for an integrated services digital network supporting a population of blockable narrowband and queueable wideband users. Numerical results are obtained for the mean wideband queue length, the probability of blocking for narrowband users and the probability of a wideband user having to compress its data rate in order to gain access. These results are compared with those of a similar strategy which does not allow wideband bit-rate compression, to assess the usefulness of using bit-rate compression to increase the traffic handling capacity of the transmission facility. Although it is found that the increase in throughputs of both wideband and narrowband traffic is significant, any adverse effects of bit-rate compression on the resultant signal quality of wideband traffic are not addressed. These must be found from subjective tests, beyond the scope of this study, for each specific type of wideband traffic. © 1990.
