ITEM NAME   COIL,TELEPHONE
DEFINITION  An item consisting of one or more turns of wire or similar conductive
             material. It is specifically designed for use in telephone circuitry
             for reducing cross talk by balancing capacitances, or impedance
             matching or providing inductive reactance for overcoming inherent
             capacitance, or inductive coupling where direct coupling is
             undesirable or discriminating against the flow of alternating current
             in favor of direct current.
