Summary:A switching system for connecting any one of a plurality of electrical circuits to any one of a plurality of test positions, wherein a central controller including a microprocessor directs, in a pre-programmed manner, all necessary switching functions. In the preferred embodiment, the electrical circuits are telephone circuits and the test positions include test ports positioned in various locations around a central office so that any of the telephone circuits can be accessed for testing from any of the test ports. The controller communicates with each of the test ports and controls switching units one at a time over a common control bus.
