<p><P>PROBLEM TO BE SOLVED: To provide a technique for controlling incorporation of a replaced communication device in a data communications system including multiplexed communication devices. <P>SOLUTION: A communication control apparatus 10 categorizes data communications into trunk business communication and generic business communication on the basis of traffic information passing through a subject communication device 2m, generates and stores operation information including information of a time band of the trunk business communication, and synchronizes the information with operation information stored in a communication device 2s. When the communication device 2m is replaced, the communication control apparatus 10 refers to the operation information, then, if the present time is other than the time band of the trunk business communications, incorporates a system onto the subject communication device 2m, and switches a data communication process from the communication device 2s to the subject communication device 2m. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
