PURPOSE:To decrease the remolding of the hardware and to enable to receive a signal of various frame forms, by setting a constant for frame synchronism programmably at memory readout and picking up data through the detection of synchronizing word. CONSTITUTION:An input frame signal inputted serially is separated at each 64- bit without interruption and overlapping through shift registers 20A and 20B and stored in each address in 64-bit length of a memory 30. The information is read from a line 302 and compared with the synchronizing word pattern preset and transmitted from a set circuit 50 at a synchronizing word detection circuit 40 to pick up the synchronizing word at the head of each frame. When the synchronism is confirmed, the data in the frame is separated at a frame format control circuit 60 and outputted to a required port 70. |
