摘要： A method and apparatus for isolating malfunctions occurring in a communication switching system having a line switching network for establishing communications selectively between calling and called lines under the control of common equipment including a plurality of registers for storing temporarily call processing information received from the calling lines via a plurality of register junctors, a junctor switching network connecting selectively a pool of sending units and receiving units to the junctors, the common equipment including memory, includes establishing a connection between a register junctor and a sender-receiver unit for test purposes, connecting testing circuits to the register junctor via the line switching network, testing the register junctor circuits to determine whether or not they can extend a path from the line switching network to the junctor switching network, testing the sender-receiver unit by means of the testing circuits via the path between the junctor and the sender-receiver unit if the junctor circuit was found to operate properly, and thereafter establishing a new path between a selected different one of the register junctors and the same sender-receiver unit under test so that the new path can be checked for continuity if the sender-receiver unit under test was found to operate properly, whereby a malfunction can be isolated to either a register junctor, sender-receiver unit or the junctor network interconnecting them.
