A connection management system comprises a plurality of sockets 1, 2 for receiving complement plugs provided on ends of cables for effecting interconnections between said sockets. Each said socket 1, 2 has an input contact 1a, 2a and an output contact 1b, 2b being electrically connected upon inserting a plug A, B into the socket 1, 2 so as to transmit the logic state. Detection of a change of said logic state at said other of said input 1a, 2a and output 1b, 2b terminals is then indicative of the presence of a plug A, B therein. A signal is then provided to one of the input and output contacts of a socket 1, 2 and the other of said input and output contacts is then monitored for the presence of said signal in order to confirm the presence of a plug A, B in the socket 1, 2.
