Abstract

An improvement of the telephone monitoring and control device includes (1) a microprocessor having data input ports to record, compute, and identify the information and the time. (2) a push-button dialing device to input the number, the symbol, and the system function key sets. (3) a real time generator to offer the time record for the microprocessor. (4) a display connected with and controlled by the microprocessor to illustrate the time, the password, and the system information. (5) a random access memory connected with and controlled by the microprocessor to read and write the data. (6) a card read-write device containing a card slot for ID card insertion to read and write the card information and a data port connected to the microprocessor to transfer the data. (7) a input/output interface connected to the microprocessor to transfer the data to all the I/O peripheral devices. (8) an output signal of the ring detecting device connected to the interrupt input terminal for informing the microprocessor about the coming of the ring signal. (9) and the combination of a row-column selector, a dual-frequency generator, and a dual-frequency decoder to decode the input dial number and transmit it to the microprocessor.
