摘要

PROBLEM TO BE SOLVED: To determine the validity of setting of a receiver, and to discriminate a part with erroneous setting.

SOLUTION: When it is decided that a physical connection confirmation packet is received in S1, processing proceeds to S2 to perform the reception processing of the physical connection confirmation packet. When a service reception confirmation packet is determined to have been received, the processing proceeds to S4 to conduct the reception processing of the service reception confirmation packet. When it is judged that both of the physical connection- and service reception confirmation packets are received in S5, the processing proceeds to S6 to decide that the whole setting has correctly been performed. When only the reception processing of the physical connection packet is determined to have been performed in S7, the processing proceeds to S8 to judge the existence of an error in upper-order setting. When it is determined that no reception processing has been performed in S7, the processing proceeds to S9 to judge the existence of the error in the physical connection.
