Abstract: PURPOSE:To make it possible to inform a user of abnormality in actuation of a microwave source inexpensively by judging as to whether the microwave source is actuated or not, by detecting the abnormality of the microwave source and by informing the user of it. CONSTITUTION:At the time of starting, a first set of timing signals 58 are generated first, and a timing signal selecting means 44 samples and stores a temperature signal is response to the first set of timing signals 58. Next, the timing signal selecting means 44 sends a timing signal selection signal 60 to the effect that a second set of timing signals should be selected, to a timing signal generating means 42. Receiving said signal, the timing signal generating means 42 stops generating the first set of timing signals, generates the second set of timing signals and samples a humidity signal in response to the timing signal 60. Then, it is judged whether or not the timing signals are generated within a period when a microwave is generated, and when the microwave is not generated in either case, a user is informed of abnormality by an information sound. Thereby the user can be informed of the abnormality faster and more inexpensively.

Abstract: PURPOSE:To sharply reduce the time required for rewriting ACM (address control memory) surfaces, by collectively inputting ACM surfaces of plural designated stations from the network monitoring processor (NSP) of a master station at once at the begining and causing the NSP of a designated slave station to rewrite the ACM surfaces. CONSTITUTION:Control information data in which circuit switching information is written and which is common to each base are successively sent to each base A, B, and C from the NSP of a master station (NSPM) at a center. At a slave station S1, the ACM surface data of a designated ACM surface number are read out from an ACM pattern table 12 and the supervisor (SV) 11 of a digital multimedia multiplexer (DMIX) 10 writes the data in an ACM 13. Similarly, at each base B and C, ACM surface data of designated ACM surface numbers are read out from ACM pattern tables and written in ACMs by means of SVs of DMIXs 20 and 30, respectively. Since the control information data of the NSPM of the master station are prepared commonly to each base in such way, it becomes unnecessary to prepare the data to each base as compared with conventional systems and ACM rewriting can be controlled in a short time.
