Multi-subscriber differentiation and distribution switching system having interchangeable differentiating circuits
First Claim
1. A differentiation and distribution switching system for connecting selected ones of a plurality of subscriber lines for receiving a desired signal, said system comprising at least two differentiation circuits, one of said differentiation circuits permitting passage of a first selected signal portion of a composite signal connected to its input, the other of said differentiation circuits permitting passage of a second selected signal portion of said composite signal, said composite signal being received from a main distribution line and connected to a splitter circuit to connect to an input of each said two differentiation circuits, and a switching circuit having a plurality of couplers connected to an output line of said differentiation circuits with a switch connected to each said couplers and an associated one of said subscriber lines whereby to connect a signal on said output line of said differentiation circuits to selected ones of said subscriber lines, each said differentiation circuit having a detachable support whereby to be easily interchanged without alteration to said switching circuit.
