Chapter 700 (1/2)

He Yanwei's promotion to the post of director of the Branch Bureau started from the grass-roots level step by step. Although he is not like the criminal police, he has been exposed to many major cases, but he also has a lot of experience in solving cases.

Judging from what the curators told us, we can basically eliminate the possibility of internal theft.

It will take some time for the trace comparison results to come out. We can't wait all the time, we have to do something.

No matter what kind of case it is, the shorter time it takes to find clues after the crime, the greater the probability of solving the case and the faster the speed of solving the case.

The reason why he Yanwei asked the police to contact the telecom company immediately to check the network problems is that people now live in a network era and know the most basic network equipment very well. He Yanwei has seen the terminal equipment of the museum, a optical cat and a router!

Optical cat is the device of optical fiber intervention, and then converted into network cable, access router.

Whether it's a light cat or a router, there are indicator lights. At this time, the light cat's indicator light or the router's indicator light shows that everything is normal.

The monitoring hard disk of the computer has been removed, and the video of cloud backup is not long after work, which shows that the network of the museum has a problem at this time.

If you want to destroy the network, the most simple and direct way is to cut off the optical fiber line.

But the light of the light cat shows that the optical fiber line is normal. What kind of method is used by the thieves entering the museum to cut off the network becomes a clue.

Neither he Yanwei nor the police officers he ordered knew the telephone number of the leader of the telecommunication company.

At this time has been off work, want to let Telecom maintenance personnel in place, must be the leader of the telecom company to arrange.

However, it is also difficult for the police. The police officer often wants to do such things. He makes a call to the customer service, connects the artificial telephone, and then tells his identity and gives his alarm number. He explains the situation in a simple but detailed way, and asks the customer service personnel to contact their on duty leaders.

In this case, the customer service staff did not dare to make the decision, and immediately reported the matter without hanging up the phone.

The leader in charge of customer service got through the phone, and the police officer told the police immediately that he would contact Nanjiang immediately, actively cooperate with the police, and let the police officer wait for the call.

Within five minutes of the police officer hanging up, the call came in. It was from the leader of the local telecom company in Nanjiang. On the phone, the leader told the police officer that the maintenance personnel and the company's engineers had been arranged to come over, and they would contact the police officer by phone.

In less than 20 minutes, two Telecom workers were in place, one was a segment repairman, the other was an engineer of the company.

After he met them, he explained the situation to them and asked them to find out the reasons for the problems in the museum network.

The engineers and maintenance workers immediately started their work. First, they checked the optical fiber, and sure enough, the optical fiber was connected. Then, they checked the optical cat and the router, and the two devices also showed that they were working normally.

The repairman even contacted the customer service and asked the customer service to check whether the museum's account number was abnormal online. The answer was that the account number was normal!

The engineer pondered for a while, and asked the repairman to come back to the company and get a new optical cat and a new router. He tried to replace the two devices, but it still didn't work. It showed that the network was not working!

This kind of situation, maintenance workers have not seen, engineers have not seen!

The shops on this street are also equipped with broadband network. They are from the same machine room as the museum. Engineers and maintenance workers went to other shops to test. The results show that the network of other shops is normal!

The engineer stayed in place, but let the maintenance workers go to the machine room to check the situation.
