Abstract

A frame-synchronous reproducing circuit (10) includes a BIC status register (20) of six stages, and a BIC status signal (c) from each stage of the register is applied to a BIC pattern determination circuit (24) in which the BIC status signal (c) and a BIC changing pattern being stored in advance are compared with each other. If the both are coincident with each other, the BIC pattern determination circuit (24) applies a high-level signal to a JK flip-flop (26) via an OR circuit (48), whereby a high-level signal representing that frame synchronization has been settled is outputted from the JK flip-flop (26).
