It is a case about trouble shooting in telecommunication network. Anson is a manager of a telecom company. It came a problem in the company’s network. It lies in the transmission stations, causing the main transmitter and the auxiliary one cannot be switched smoothly. Anson and his colleagues had been working hard to locate the exact problem for weeks however still unclear.
It’s so technical and requires expertise. Anyway we still can see what information the model can provide to assist.
According to the model, a station at the south direction, about 18 kilometers away has a problem. Anson told, that shall be the transmitter #6.
Have a look at the details, it shall be a plastic part, round shape, which has hole in the middle, functioning not well. It shall locate in the upper part or floor of the station. In addition, it is not a new problem but old.
With this information, Anson and his colleagues went to the station.
As Anson’s final update, the circuit board in the control room of the station is aged. Its contact to the auxiliary power is poor. So causing the problem. When the old circuit board replaced, the problem is solved.
In addition to that, transmitter #5 has the similar problem.
How is the information provided by the model? Firstly I looked at the symbol of problem. It falls in segment #6, where is of round shape and has metal nature. Symbols in the segment has element X, which control airflow. That’s why I said the problematic part shall has a hole in the middle for air circulation.
The distance and direction of the problem are judged by the direction of the segment #6.
Anson is acting as doctor to the problem. He sits in a segment that subdues the problem segment. So the problem can be resolved.
