Abstract
Disclosed is a circuit which permits a customer to be disconnected from a telecommunications network for testing purposes. The circuit includes a pair of switching means coupled to the tip and ring conductors of the network, and a pair of relay contacts coupled in parallel with respective switching means. The relay contacts are operated by a relay coil also coupled to the tip and ring conductors so that the switching means can be bypassed as the result of a remote signal from the network.
