ABSTRACT:
This invention relates to a terminal interface for interconnection of one or more subscriber telephone lines. The interconnections are made, in the interface box, by non-wire connections such as a bus composed of parallel and longitudinal blades or a cut-out circuit. The compartment for the Distributor receives a module for rapid interconnection of telephone lines, and preferably, a protective module and an R-C module. The connections for the Subscriber comprise, in addition to another rapid interconnection module, a telephone test socket which is associated with electro-mechanical means which electrically insulate the Subscriber's line from the incoming line as soon as it is desired to plug into this socket a conjugate telephone plug.
