Title: Multi-frame synchronism inspecting circuit
Inventor: UCHIZONO TAKEJI
IPC: H04L7/08
Filed: 1988-04-01
Abstract: PURPOSE:To smoothly set up and reset up the multi-synchronism in a simple constitution and with sure actions by setting up the synchronisms independently of each other and giving the prescribed priority orders to these set-up actions. CONSTITUTION:When the frame synchronism is set up, an FA synchronism protecting circuit can start to start the FA synchronism inspection. Then an M synchronism protecting circuit 208 can work to start the M synchronism inspection for set-up of the M synchronism after the FA synchronism is set up. When the frame step-up occurs, both circuits 206 and 208 are reset and both FA and M synchronisms are stepped out. At the same time, the M synchronism is stepped out when the FA synchronism is stepped out. Thus both synchronisms are set up again and the M synchronism is set up again in case only this synchronism is stepped out.

Title: Call signal detection circuit
Inventor: YAMAGUCHI SHINGO
IPC: H04N1/32
Filed: 1985-04-15
Abstract: PURPOSE:To detect a call signal accurately by ignoring the waveform fluctuation of one polarity until the other polarity is stabilized at specific level after the one polarity of the AC waveform of call signal has been detected to have stabilized at a specific level. CONSTITUTION:Since the AC voltage of call signal supplies the current to photo connecting element PC1 or PC2, the phase of output signals 16, 18 of inverter INV1 and INV2 is reversed each other. On the other hand, when FF1 is being reset state, and if the output signal 16 becomes high level because an input 24 of gate G1 is energized thereto, an output 20 of G1 becomes high level, and FF1 is set. In this situation. FF1 will not be reset until the output signal 18 becomes high level because an input 26 of gate G2 is energized. Accord ingly, as the FF1 will not be reset if it is once set as far as PC2 is not driven, no erroneous action will be taken, even if there is a deformation in call signal.
