  First, the management device 30 receives a network configuration diagram display instruction from the user, generates a wiring information request, and transmits it to the main device 20 (S400). The main device 20 that has received the wiring information request generates an individual wiring information request and transmits the generated individual wiring information request to all the extension telephones 50, for example, by broadcast or multicast (S401).

  Upon receiving the individual wiring information request, the extension telephone 50-1 generates an individual wiring information response including the information communication device information 742 of the own device destined for the main device 20, and the generated individual wiring information response is transmitted to the relay device 40-. 3 is transmitted (S402). The relay device 40-3 that has received the individual wiring information response adds the relay device information including the identification information of the own device and the port number that has received the individual wiring information response to the individual wiring information response (S403). Then, the relay device 40-3 transfers the individual wiring information response to which the relay device information of the own device is added to the relay device 40-2 (S404).

  The relay device 40-2 that has received the individual wiring information response adds the relay device information of the own device to the individual wiring information response (S405), similarly to the relay device 40-3, and adds the relay device information of the own device. The added individual wiring information response is transferred to the relay device 40-1 (S406).

  Similarly to the relay device 40-2, the relay device 40-1 that has received the individual wiring information response also adds the relay device information of its own device to the individual wiring information response (S407), and adds the relay device information of its own device. The added individual wiring information response is transferred to the relay device 40-1 (S408).

  The main device 20 holds the received individual wiring information response in the memory, and when receiving the individual wiring information responses from all the extension telephones 50, the main device 20 uses the individual wiring information included in the received individual wiring information responses from the communication system 10. A wiring information response including the entire wiring information is generated (S409), and the generated wiring information response is transmitted to the management apparatus 30 (S410). The management device 30 generates a network configuration diagram from the wiring information included in the received wiring information response and displays it on the display device (S411).

  The embodiment of the present invention has been described above.

  As is clear from the above description, according to the communication system 10 of the present embodiment, information indicating the network configuration can be collected even in a network configured by the relay device 40 operating in layer 2.

  In the above, the present invention has been described using the embodiment. However, the technical scope of the present invention is not limited to the scope described in the embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above-described embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
