Abstract
In order to increase the information exchange speed among the several transaction members or subsystems organized around a bus carried on a backpanel, all lines of the bus are isolated, using CMOS switches, from the stub to each transaction member which is not instantaneously required for information exchange. The CMOS switches are physically placed as close as practical to the junction of each individual stub to the bus proper. This is achieved by placing the integrated circuits containing the CMOS switches on each subsystem circuit board proximate the male-edge-connector-to-female-edge-connector regions at which the junctions between the bus proper and the stubs are established. Preferably, the CMOS switch integrated circuits are emplaced on the backpanel itself proximate the edge connector regions communicating with each of the subsystems.
