[0077]
Following the control processing of FIG. 7, a description will be given of a user port setting control procedure processed on the communication device side shown in FIG.
[0078]
The control unit 808 receives packet data for port connection control from the network management device 60 via the management port 112 and the external communication interface 809 (step S81).
[0079]
The control unit 808 analyzes the received packet data, and outputs user port identification information and setting information to be changed to the port connection control unit 804 (step S82).
[0080]
The port connection control unit 804 notifies the control unit 808 of the result of the setting after switching the operation start or stop of the corresponding user port based on the received setting information (step S83).
[0081]
The control unit 808 updates the operation data of the corresponding user port managed on the memory 807 based on the setting result from the port connection control unit 804 (step S84).
[0082]
The control unit 808 outputs a request to the LED display control unit 803 to change the lighting pattern of the LED display unit corresponding to the user port 11 for which the setting change has occurred in accordance with the operation status of the user port performed in step S83. (Step S85).
[0083]
Next, an example in which the administrator monitors the user port 11 of the communication device 100 by the network management device 60 shown in the flowcharts of FIGS. 5 to 8 will be described.
[0084]
FIG. 9 shows an example of a management screen in the network management device 60.
[0085]
A management window 72 is displayed on the display device 71 of the network management device 60, and a device external view 53 showing the same external appearance as the indoor device 110 is displayed in the management window 72.
[0086]
Further, in the external view 53 of the apparatus, a user port 75 and an LED section 74 having the same appearance as the user port section 111 of the indoor apparatus 110 are displayed.
[0087]
In the LED unit 74, a green LED 74-1 and a red LED 74-2 are displayed for each user port 75-1 in the same layout as the indoor device 110, and the display of the green LED 74-1 and the red LED 74-2 is Are displayed in conjunction with changes in the actual LED display pattern of the indoor device 110.
[0088]
For this reason, the administrator sets the connection status and the service provision status of the indoor device 110 operating on the network to the green LED 74-1 and the red LED 74-2 of each user port 75-1 of the display device 71 of the network management device 60. Remote monitoring is possible from the display.
[0089]
For example, when a communication error occurs due to a disconnection of a cable connected to a certain user port 11 of the indoor device 110 or a failure on the user network 32 side, each user port 75 of the external part 73 of the display device 71 that has detected the error. The display of the green LED 74-1 and the red LED 74-2 of -1 changes according to the display patterns of FIGS. 4A and 4B.
[0090]
Thus, the administrator can check the LED unit 74 displayed on the display device 71 of the network management device 60 and quickly perform the failure analysis and the repair work on the indoor device 110.
[0091]
The screen image of FIG. 10 is a screen image of the display device 71 when the network management device 60 remotely monitors the operation status when three communication devices 100 are operating on the network.

[0096]
At this time, when the LED unit 74 is viewed in the management window 72 of the communication device A, the LED display pattern of the failed port is as shown in FIG.
[0097]
Therefore, when remotely monitoring a plurality of indoor units 110 via a network, the management window 72 of the display device 71 of the network management device 60 determines which user port of which indoor unit 110 is abnormal by the screen transition. It is possible to narrow down and confirm.
[0098]
Further, when each communication path provided by each user port 11 of the indoor device 110 is provided for a fee, the administrator starts the service by making the user port 11 communicable with the indoor device 110 by the communication activation function. Alternatively, it is possible to control the communication connection by setting the user port 11 in a communication disabled state by the operation stop function.
[0099]
At this time, the red LED 74-2 and the green LED 74-1 of the user port 75-1 set to the operation stop state in the LED section 74 of the device in FIG. 53 displayed on the management window 72 are shown in FIG. ).
