After two days of preparation, Ding Chi began to personally lead the team to test the journey. In addition to the technical personnel of Ding Kui Company, the general agent Liang Arui also sent people, and he was the deputy general manager of technology. After Zheng Junfeng learned the news, he called Ding Chi and said that the post and telecommunications system would fully cooperate, and he had already made a request to the person in charge of the post and telecommunications of the prefecture.

Ding Chi's first stop was Hongliushan City, which is also the city where the problem is more concentrated this time.

When Ding Chi arrived with people, Wen Dacheng, the city-level agent, had already led the crowd to wait, and the people from the Municipal Post and Telecommunications Bureau and the Municipal Unicom were also present, indicating that they had paid enough attention to it and also showed the seriousness of the problem.

After everyone met, they did not greet each other too much, but simply touched the problem, forming a unified detection idea. In fact, most of the relevant tests have been carried out, but after all, the cause has not been found, and this time it is the provincial agent who came in person, so it is necessary to test more strictly, in order to find out the crux of the problem.

After finalizing the detection idea, we first started to investigate from the urban area, and selected several areas where the problem was concentrated. Under the witness of the agents at all levels of the "Jinsheng" telephone, the post and telecommunications and Unicom respectively inspected the facilities in their respective areas, and the test results showed that the facilities and equipment were all normal, and the wireless network signal was fully up to standard.

Then there is the entrance inspection, which not only tests the signal strength again, but also carefully checks the entrance line, even if it is a slight crease, it must be carefully disposed of, and the phone is a mandatory content. After more than 20 households checked, the home line and signal are still normal, and the phone has no quality problems, and the real-time call is clear and stable. But the customers are sure that there are often problems during this time, otherwise they will not find suppliers, and when they change to other brands, the original problems basically do not appear.

It can be seen that these people don't seem to make something out of nothing, and it is impossible to coax together, otherwise they will definitely show some horses. So after communication, they were divided into five groups, and they were monitored at the customer's home, and a test was more than half a day, and even some people monitored 24 hours a day, and no problems were found.

Is this strange? Is there a ghost? Ghosts definitely don't exist, but the problem is that customers are still not at ease, worried about the "recurrence of old diseases" on the phone.

Changing the area again, it was two more areas to check down, everything was the same, and no problems were found.

In this way, not only Ding Chi and others were puzzled, but the customer was also at a loss.

In order to prove his remarks, the attentive customer Uncle Wang specially provided a recording, which was recorded with a tape recorder during the call.

"Ding Bang", the telephone rings from the tape recorder, and then the phone tone and current sound are picked up, and the interference sound of "buzzing", and then there is a conversation between men and women:

Man: "Is your voice clear?"

Woman: "It's loud. Dad, what's in front of the phone?"

M: "There's only one tape recorder, and I'll play it in the distance." In the past few days, it has been ringing even without it, and I can't hear it clearly. ”

Two bursts of footsteps sounded on the tape recorder, and the conversation between men and women was correspondingly quieter:

Man: "What about this time?"

Woman: "It's still like that." Dad, if you are louder, I can't hear you clearly. ”

Man: "My voice is smoking, mainly because the noise is too strong...... Hey, hey, what's not moving?"

The conversation in the tape recorder came to an abrupt end, but the "buzz" was still there, and it was only after the "pop" hang-up sound that the noise stopped.

Everyone looked at each other, and they heard it clearly just now, and it was true that there was a murmur disturbing during the call.

Turning off the tape recorder, Uncle Wang explained: "I used to be like this for more than half a month, and there was a murmur at least eight times out of ten phone calls, so in order to be able to explain things clearly, I just recorded it." If it weren't for the bad phone, I wouldn't have time to find you, and I might as well have the time to 'put up the Great Wall' with my brother." Now that you've listened, I'm not talking nonsense, am I?"

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

Uncle Wang pointed to the back cover of the battery and explained: "I broke this place, mainly because of the old noise at the time, and I thought about tinkering with it myself, and I ...... it if I was not careful."

"It doesn't matter, the noise has nothing to do with being bad here. Ding Chi said, giving the cordless phone to the technician.

Several parties were present, and the small equipment and testing pens were all on the same page, but no problems were detected.

Subsequently, several levels of suppliers, equipment supporting departments, and customers tried to make calls respectively, and the call quality was clear, the call was stable, and there was no problem.

Understand, understand more. The customer did not ask for a return for the time being, but repeatedly emphasized that "get it done quickly". Ding Chi and the others were sincere, kept apologizing and assuring, and then left Uncle Wang's house.

The urban area did not find out the crux of the problem, and it was divided into counties, and the result was the same.

Nothing has been found yet, three days have passed. This was not possible at this pace, so the people were divided into five groups and went to various cities. Subsequently, the information slowly and continuously gathered to Ding Chi: the equipment of post and telecommunications and China Unicom was fine, the network signal was completely normal, and the telephone was no problem.

During this period, not only Ding Chi and others paid attention, but Liang Arui and Zheng Junfeng also asked at any time and gave analysis. While the content of the analyses varies, one thing is unanimous: continue to look for sources of interference.

Before I could continue to search, the agent reported the information again: many customers reported call quality problems, some of them just reflected, and some of them had just been tested.

What should I do? People got together and discussed countermeasures, and there was a lot of discussion and a lot of noise.

Seeing that people were talking about the same, and they were always turning over and over again, Ding Chi cleared his throat and opened his mouth: "There is no need to explain their respective difficulties, everyone has seen that the whole test is indeed no problem, but the customer has repeatedly insisted that the problem exists." Although we didn't catch up with the call to find out the situation, but we all recognized the situation reported by the customer, so there is nothing else to say, we can only work together to find out the crux of the problem, otherwise no one can get out of trouble. ”

Although they all feel aggrieved from their respective positions, what Ding Chi said is also the truth. With such a large area of problems, it is impossible for customers not to look for them, so relevant departments and industries should not want to hide from them. Most of them didn't speak, waiting to hear Ding Chi's next words.

But the vice president of Hongliushan Unicom Niu said: "I will say a few words, which may not be right, but I have a little doubt." In addition, I have noticed that many customers have emphasized that there is nothing to do with other brands, but once they use that brand, they are lacking, and they are all new buyers recently, why is this?

Why? People are looking at Ding Chi to see his reaction. Everyone heard it, and Vice President Niu said it very clearly, "The problem is on the 'Jinsheng' phone, but the sign is not directly clicked."

Without waiting for Ding Chi to speak, Wen Dacheng answered: "I also have a little question, why is there no problem in the four districts of our city one after another?"

Vice President Niu smiled: "Old Wen, do you mean that the Unicom, post and telecommunications work of more than ten prefectures and cities is not effective, and there are problems with equipment and signal support?"

Although it is clear that this is a cause for disaster, the people in charge of China Unicom and Post and Telecommunications still have anger on their faces.

"Ding Woo Bang", the bell rang suddenly.

Wen Dacheng took out his mobile phone and immediately connected: "Yes, in ...... Steady, I'll go back right away. ”

Noticing Wen Dacheng's tone and look, people couldn't help but ask: What happened?
