Abandon this year's network rules and switch to GCT

I wanted to give up GCT because of the money I spent on the decoration. Now I want to pass the GCT because I want to review the situation. I can't go through the internet rules, so I can't waste time. I will take a title in English next spring. Alas ...... The network rules are so scrawled. Although unwilling to do so, I feel much more relaxed. In the past two days, I have to draw the network topology of the Organization and arrange the fire training examination. Come on one by one. The English is too bad to read at all. You have to find a solution.

The most serious impact of network delay attenuation is high-speed and analog signals.
