L-419, FRAMING CIRCUIT FOR DIGITAL SIGNALS USING EVENLY SPACED ALTERNATING FRAMING BITS, by, Ralph LeRoy Kline ABSTRACT OF THE DISCLOSURE, In a digital multiplexer which employs pulse stuffing and a plurality of signaling bits including evenly spaced framing bits a, framing circuit consists essentially of a pair of flip-flops which store the last values of a winking framing signal or the error signal which may have occurred during the framing time slots. Outputs of the flip-flops are connected to gating circuits. One said gate produces an output signal when an error occurs. This error signal is applied to an error density detector. When an out-of-frame condition occurs i.e. the, receiving …
