After two days of preparation, Ding Chi began to lead the inspection tour in person. In addition to the technical staff of Dingling Lynin Company, the general agent Liang Arui also sent people, and was led by the deputy technical general. After Zheng Junfeng learned the news, he called Ding Chi specifically, saying that the postal and telecommunications system would cooperate fully, and he had made requirements with the postal and telecommunications head of the prefecture and city.

Ding Chi's first stop is Hongliushan City, which is also the prefecture with more concentrated problems this time.

When Ding Chi brought his men to arrive, the municipal agent Wen Dacheng had already led the crowd to wait, and the Municipal Post and Telecommunications Bureau and the Municipal Unicom were also present, which shows that they all paid enough attention and also shows the seriousness of the problem.

After everyone met, they did not exchange too many greetings, but simply encountered problems, forming a unified detection idea. In fact, most of the relevant inspections have been carried out, but after all, the reason was not found. Moreover, this time the provincial agent came in person, so they had to conduct more strict inspections in order to find out the crux of the problem.

After finalizing the inspection ideas, we first started to check the city and selected several areas with relatively concentrated problems. Under the witness of agents at all levels of "Jinsheng" telephone, postal and telecommunications and China Unicom respectively checked the facilities in their respective areas. The test results were that all the facilities and equipment were normal and the wireless network signals were fully met.

Then there is home entry inspection. Not only does the signal strength be tested again, but the home entry route is also carefully checked. Even slight creases must be dealt with seriously. The phone is a must-check content. After more than 20 households checked the home entry route, the signal was still normal, the phone had no quality problems, and the real-time call was clear and stable. But customers insisted that problems often occurred during this period, otherwise they would not have found suppliers. Moreover, when changing other brands, the original problems basically did not appear.

It can be seen that these people do not seem to be out of nothing, and they cannot make fun of each other, otherwise they will definitely show some flaws. So after communication, they are divided into five groups and monitored on site at the client's house. After testing, it takes more than half a day, or even 24 hours a day to monitor, but no problems are found.

Is this strange? Is there a ghost? The ghost definitely does not exist, but the problem is that the customer is still worried and worried that the phone will "recur" the old illness.

I changed the area and found two more areas, but everything was the same, but no problem was found.

As a result, not only Ding Chi and others were confused, but the customers were also puzzled.

In order to prove his comments, the careful client, Uncle Wang, specially provided recordings, which were recorded on the recorder during the call.

"Dingling" sounds from the recorder, then the phone ringing sounds, the current sounds, and the interference sounds of "Buzzing Wing" are heard, and then the conversation between men and women is heard:

Male: "Do you have a clear voice?"

Female: "It's ringing so loud. Dad, what's there in front of the phone?"

Man: "There is only one recorder, and I will put it in the distance. In recent days, it still rings without it, and I can't hear it clearly."

Two sets of footsteps sounded in the recorder, and the conversation between men and women was lowered accordingly:

Man: "What about this time? Are you clear?"

Female: "It's still the same. Dad, if you say louder, I can't hear it clearly."

Man: "My voice was smoking, but the main reason was that the noise was too strong... Hello, hey, why didn't you move?"

The conversation in the recorder came to an abrupt end, but the "buzzing" sound was still there, and the noise was gone until the "bang" sounded.

Everyone looked at each other, and they heard clearly just now that there was always noise disturbance during the call.

Turning off the tape recorder, Uncle Wang made an explanation: "I used to be like this for more than half a month. There were noises at least eight times when I called ten times. In order to make it clear, I only recorded it. If the phone wasn't working, I wouldn't have time to find you. If there was time, I would be better than brothers and others to 'set up the Great Wall'. Now you have listened, I'm not talking nonsense, right?"

After Ding Chi smiled and signaled, he took two steps forward, picked up the phone and observed it.

Uncle Wang pointed to the battery back cover and explained: "I broke this place, mainly because Lao Xiang was thinking about tinkering with it, but he accidentally..."

"This does not affect it, the noise has nothing to do with the bad here." Ding Chi said, giving the cordless phone to the technician.

Several parties were present, with small equipment and detection pens on the scene, and no problems were detected.

Subsequently, several levels of suppliers, equipment supporting departments, and customers tried to make calls separately, with clear quality and stable calls without any problems.

Understand, understand more. The customer did not make a return request for the time being, but repeatedly emphasized "get it done quickly." Ding Chi and others were sincere in their attitude, constantly apologizing and guaranteeing, and then left Uncle Wang's house.

The city did not find the crux of the problem and was grouped into the county, and the result was the same.

Nothing was found yet, and three days had passed. According to this progress, people were divided into five groups and went to various cities. Then, the information slowly and continuously gathered to Ding Chi: the equipment of the post and telecommunications, the network signal was completely normal, and the telephone was also fine.

During this period, not only Ding Chi and others were concerned, but Liang Arui and Zheng Junfeng also asked about it at any time and gave analysis. Although the analysis contents are different, one thing is consensus: continue to look for sources of interference.

Before we could continue to search, the agent once again reported the information: many customers reported the call quality problems, some just reported it, and some just tested it.

What should I do? People gathered together and discussed countermeasures, and they were talking about it for a while, and they were very noisy.

Seeing that people were almost saying it, they were always talking over and over again, Ding Chi cleared his throat and said, "No need to explain their own difficulties. Everyone has seen it. The whole test is indeed fine, but the customer has repeatedly insisted that the problem exists. Although we didn't catch up with the call, we all agreed with the customer's reporting of the situation. So if there is nothing else, we can only work together to find out the crux of the problem, otherwise no one can get rid of the trouble."

Although they feel wronged from their own standpoint, what Ding Chi said is true. With such a large area of ​​problems, it is impossible for customers not to look for them, so the relevant departments and industries cannot avoid leisure. Most people didn't say anything, waiting to listen to Ding Chi's following.

But Vice President Niu of Hongliushan Unicom said: "I may not be right if I say a few words, but I am just a little bit of my doubt. After the inspections these days, no problems were found, but why did the customers say that? In addition, I also noticed that many customers have emphasized that there is nothing to do with other brands, but when they use that brand, they are all new machine buyers recently. Why is that?"

Why? People turned their attention to Ding Chi, wanting to see his reaction. Everyone heard it. Vice President Niu was very clear about what he said, "The problem lies with the 'Jinsheng' phone number, but he didn't just click the sign.

Before Ding Chi could speak, Wen Dacheng answered: "I also have a little doubt, why did our city suffer one after another, and there were no problems in the four districts of Weicheng City?"

Vice President Niu smiled: "Old Wen, what do you mean is that China Unicom in more than a dozen cities and cities have poor postal and telecommunications work, and there are problems with equipment and signal support?"

Although it shows that this is a disaster, the people in charge of China Unicom and the post and telecommunications still show anger on their faces.

"Dingling" and the ringtone suddenly rang.

Wen Dacheng took out his cell phone and immediately answered it: "Yes, what? Stay stable, I'll go back immediately."
