A telecommunications system and constituent two-wire interface module. The two wire interface module includes a logic component configured to communicate over the same pair of wires using different two-wire interface protocols depending on an input signal presented on a configuration input. This configurability allows the two-wire interface module to use the same two wires to communicate with a variety of other two-wire interface modules, even if those two-wire interface modules communicate using different two-wire interface protocols.
