Title:
CENTRALIZED MONITORING OR CENTRALIZED CONTROL CIRCUIT
Document Type and Number:
Japanese Patent JPH06326681
Kind Code:
A
Abstract:

PURPOSE: To reduce the number of monitoring or control interfaces with an outside part and to easily cope with the increase, decrease and change of monitoring or control object circuits by providing a centralized monitoring information transmission circuit or a control information reception circuit and respective interface memories and distributing and transferring the information to the respective monitoring object circuits or control object circuits again.

CONSTITUTION: Inside a transmission line terminating substrate, transmission line terminating information, path terminating information and self monitoring information, etc., are generated. Then, the monitoring object circuit 8 writes the information at the position of the specified address of a monitoring object memory 14. Also, the control object circuit 7 reads data written in a control object memory 13, instructs overhead information, duplex changeover and the lighting conditions of a lamp, etc., and performs various kinds of setting. In the meantime, a sequence ROM 16 reads arithmetic data stored in the set address and delivers them to an arithmetic circuit 15. The arithmetic circuit 15 performs data transfer and arithmetic operations between a register for the arithmetic operation within the circuit and the respective control object memories.
