。 It is installed separately from the exchange and has a test section, control section,
A test section interface circuit that interfaces with the test section in the subscriber line exchange maintenance equipment consisting of the test center communication section, and a subscriber line test device for relaying information from the maintenance center's subscriber line test device to the test section. A transmission characteristic test device for testing a relay line is connected to the test center communication section, which is composed of n interface circuits, and an arbitrary circuit among the n subscriber line test interface circuits. A transmission characteristic test device interface circuit consisting of a level exchange circuit for level conversion between the transmission characteristic test device and the interface circuit and a speed conversion circuit for speed conversion is added to the test section so that it can be connected instead of the transmission characteristic test device and the interface circuit. It has a package structure that can be replaced with the subscriber line test equipment interface circuit, and if the exchange to be maintained is a relay system, the transmission characteristic test equipment interface circuit is inserted, and if it is a subscriber system, the subscriber line test equipment interface circuit is inserted. A switching equipment maintenance device characterized in that by inserting a circuit, a single switching equipment maintenance device can perform maintenance even when a relay switching equipment, a subscriber line switching equipment, and a mixed switching equipment are used.
