Performance characterization for a dual-channel multimedia multiplexer

An efficient system for simultaneously multiplexing a large number of isochronous and asynchronous data channels over a much smaller number of communication channels is presented. The multiplexer uses a dual-channel as a switching media. Perfect time-division multiplexing scheduling for the carrier-sense channel is achieved. Each DSO channel of a T1 trunk is addressable. The high switching efficiency comes from the employment of the digital signal energy detection in each isochronous DSO channel. Voice and real-time data are multiplexed synchronously. The exact formula of the delay-throughput analysis for the asynchronous data is derived. The effect of mean voice talkspurts length is addressed for the delay performance of the asynchronous data traffic. When no hangover time is added to the speech energy detection, the asynchronous data packet delay time is proven to be very small
