This configuration is installed at a total of six sites using our (ALMSA, St. Louis, Mo.) own developed software. We do not use TCP/IP. The speeds of data interchange among all these super hosts has been limited only to the channel speeds of the slowest host. We are averaging at each location approximately 1.5 megabytes of data per second across multiple hosts. We have had two pairs of hosts carrying on data interchange concurrently with each pair averaging the same high 1.5 megabytes per second equating to 3.0 megabytes (30 megabits) per second across the hyperchannel. We are so satisfied with the performance of the hyperchannel and our software, that we are investigating expansion of the local network and linking our six sites together (possibly using Hyperlink).
