Abstract:
A communications interface system for facilitating communications between a communications system and a communication device comprising:a) a signaling transmitter for generating and transmitting encoded signals; and b) an interface adapter circuit for interfacing a communications system with a communication device, said interface adapter circuit including: 1) a signaling receiver for receiving said encoded signals from said signaling transmitter; 2) a decoder and control signal generator for decoding said received signals and generating control signals in response thereto; 3) an impedance matching and line interface circuit for interfacing a communications system to a communication device, said impedance matching and line interface circuit being controllable in response to said control signals; and said impedance matching and line interface circuit including a programming terminal block including a plurality of terminals for selectively connecting one or more external electrical components to said circuit for selectively programming said impedance matching and line interface circuit.
