Abstract
An attenuator introduces a known attenuation into telephone circuitry at connecting block terminals of incoming and outgoing, tip and ring lines when clipped thereto. The attenuator is particularly suited for attachment to an insulation displacement terminating block, known as a 66 type block, for telephone wire circuits or pairs. An attenuation network in the form of a balanced square pad is mounted on a substrate to form a printed circuit board and resistance assembly. Electrical contact means include four electrical contacts that have tail portions connected to the attenuation network and clip portions that grip the connecting block terminals of the incoming and outgoing, tip and ring lines. The printed circuit board and resistance assembly and the electrical contact means are received within a protective, insulating cover and retained therein by potting material. The attenuation rating or loss for the attenuator is marked on the top surface of the cover.
