IPC: H04L7/00
Filed: 1991-07-31
Abstract: PURPOSE:To detect precisely clock interruption without mis-detection and incurring increase in an interface. CONSTITUTION:Capacitors 4, 5 on a board A at a sender side eliminate a DC component from a clock signal and the result is sent to a transmission L. Moreover, a clock interrupt detection circuit 3 on the board A monitors clock interruption based on the presence of supply of a clock signal to a driver 1. When the clock interrupt detection circuit 3 detects clock interruption, the circuit 3 sends a DC signal to the transmission line L. On the other hand, capacitors 6, 7 on a board B of a receiver side extract only an AC component in a signal sent through the transmission line L and gives it to a receiver. Furthermore, the DC component is extracted from the input signal to the capacitor 7 and it is used as an alarm signal.
