Arnold Albert Schellenberg: Arrangement to supervise the operation of coder and decoder circuits in a pcm-tdm system. International Standard Electric Corporation New York NY, C Cornell Remsen Jr, Walter J Baum, Paul W Hemminger, Percy P Lantzy, Philip M Bolton, Isidore Togut, Charles L Johnson Jr, August 8, 1972: US3683115 (12 worldwide citation)

The coder and decoder of a terminal are placed in a closed loop excluded from the normal transmission lines during sync time and/or signalling time. During this time a low frequency test signal is applied to the coder and a comparison circuit. By gate means the output of the coder is directly couple ...
