REMOTE MONITERING DEVICE OF EXCHANGER

摘要

PURPOSE: A remote monitoring device of an exchange is provided to monitor state information of an exchange system in a remote place through a telephone line, so as to confirm an error. CONSTITUTION: An A/D(Analog-to-Digital) converter(204) converts monitoring data transmitted by being connected with a transmission line of an exchange(100) into digital data. A RAM(205) temporarily stores the data converted in the A/D converter(204). A serial input/output unit(208) connected with a personal computer(102) converts parallel data inputted/outputted in the RAM(205) into serial data, to transceive the converted data in an RS-232C system. And a controller(207) controls operations of each component.
