The same number is redundantly set as the extension number associated to a fourth telephone number in different data tables associated to different second telephone numbers. For this reason, it is possible to maintain outstanding scalability of the system in a situation where the total number of settable numbers is limited. Further, even if an outgoing call is made to a caller side terminal from a lost receiver side terminal using the call register, the receiver number is recognized to be either an extension number associated to a fourth telephone number or an extension number associated to a fifth telephone number, and an instruction to disconnect a first call is sent to the call controller. As a result, the above-mentioned outgoing call (first call) from the lost receiver side terminal is disconnected, thereby making it possible to fully ensure security when a terminal is lost.
摘要:
A storage unit for an occupant detection system detecting an occupant based on a magnitude correlation between a detection load value obtained by a load sensor and a threshold value, the storage unit includes a first ROM storing either one of the threshold value and a threshold value specific information for identifying the threshold value, the first ROM being rewritable and a second ROM storing information except for either one of the threshold value and the threshold value specific information, a rewriting of the second ROM being more difficult than a rewriting of the first ROM.
