Guo Qian, who was about to leave, immediately stopped, looked up at the man who had just said good things for her, and said, "Are you here to help us open the switch? Not to help us cut over users,...... ,That's it.,That's not necessary.,We've already opened and debugged.。 Don't you see these lights above that show it's working?"

If you are really familiar with the switch, you don't need to open the cabinet door, just look at a few indicators on the switch panel to determine whether the switch is running and whether it is operating normally.

I don't know if it was because Gu Xian's attention was focused on Guo Qian, or because he concluded in his heart that no one could open the switch, although his eyes saw those few indicators, he didn't judge that the switch had been turned on and was operating normally in the first time. Listening to her words, he couldn't help but be stunned.

"Ahh

Guo Qian proudly walked up to the switch, opened the switch cabinet door, pointed to the circuit board inside with a smile and said, "You are experts, you should know by looking at the indicators on these circuit boards, right?"

Although I don't believe it, I still tend to admit that the switch in front of me is really open, and I only feel a fever in my face and feel embarrassed.

And those who have not been trained in process control switches don't know how to look at it at all, and they absolutely don't think that even the switches that they can't turn on are opened by the Red Star Coal Mine itself, so they say loudly that it is impossible, it is absolutely impossible, what is it that a few lights are on? There must be light-emitting diodes when the power is turned on.

However, after seeing the ugly expressions on the faces of Chief Meng, Gao Jianke and other leaders, they also closed their mouths and were stunned one by one.

Compared with the technicians and leaders of the Yiyang City Telecommunications Bureau and the Fengjia County Post and Telecommunications Bureau who were slapped in the face by the people who came in front of their superiors, and relative to the resentment in their hearts, Ling Guxian from the Ministry of Posts and Telecommunications did not feel this humiliation, because the responsibility was not his, but that they did not grasp the situation in a timely and accurate manner. Moreover, now that the switch is turned on, he has almost no loss, at most he has lost an opportunity to show off in front of them, but at the same time, it also reduces the risk of losing his face if he may not be able to open it.

Comparatively, he still earned.

So he smiled and said, "It's okay, I don't have to show my ugliness in front of you." Originally, this sentence was very decent, and it was given to both sides of the stairs, and he seemed very modest in his words, and it seemed that he was very generous, and he didn't care about running in vain today, but then he said something that made him almost regret it later.

I only heard him ask Guo Qian kindly: "How long did it take you to open this switch?"

Maybe he just accosted Guo Qian when he saw that she was beautiful, or he was still a little unconvinced in his heart, after all, he thought that no one in the entire Yiyang City could open this kind of American switch, and he bragged to his classmates, but the current reality is equivalent to a slap in the face, even if his classmates don't say it.

Listening to his words, the people around them all looked at Guo Qian.

If Guo Qian answers him honestly, no matter how much time she says, everyone will not have too many ideas, at most, they will be surprised that this person is capable, or they don't believe what she said.

But now Guo Qian cares about Jiang Xinwei, and wants more people to know Jiang Xinwei's extraordinary ability, so that the people she admires can be appreciated by more people, and at the same time, she also wants to understand the level she has achieved by studying the knowledge of the exchange diligently for so many days, only to hear her ask in a ghostly manner: "If you are asked to open it, how long will it take?"

Hearing her words, the others didn't react, but Ling Gu Xian secretly screamed in his heart, only to know that he had asked a stupid question, and he didn't know how to answer her question now, and he didn't know how long to say it was the best.

If you hadn't told everyone in the car that it would take a week to open it, you could have said that it would have been three days or even two days now, but if you have been talking for a week, and now you have suddenly shortened the time significantly, everyone else will say in your heart that you are bragging: knowing that the switch has been opened, you will wantonly say that you can open it in three days.

But if you talk about a week, it seems too unlevel in front of this little girl, you must know that he said in the car at that time that he had enough insurance for a week.

I saw him roll his eyes, and said with a smile: "If you sit down and open it specifically, it is estimated that it will take about three days, after all, I have not seen it, and I may not understand many aspects, so I have to observe it while opening it." …… What about you?"

Hearing that he squeezed the time by more than half, several people quietly glanced at each other, but did not say anything, after all, people did not add the premise of "sit down and open it specifically" when they spoke in the car, and they also hoped to make the ancient string watch xiàn out of a high level, this little girl in the town and the person who opened the switch, let them not be too proud.

In the eyes of Ling Guxian and others, three days is enough to defy the sky, and the other party cannot be faster than this time.

Unexpectedly, Guo Qian smiled and said, "It took less than three hours for my master to open it. If he wasn't there to teach us to learn, it would have been opened in less than two hours. ”

"Impossible!" Ling Gu Xian vetoed, and then, he sneered at her, "You can't brag like that!"

Guo Qian was still smiling, and said: "I only need six hours to open it and debug it now, and he is my master, and it definitely doesn't take two hours." …… At that time, it was also the first time he had seen this kind of switch, and he had never known it before. ”

"Ahh

Guo Qian nodded, looked at the switch with good-looking eyes, and said, "I didn't understand it before, but I understand a lot now." However, I didn't even learn a hundredth of him. He's amazing, better than anyone I've ever seen. ”

Ling Guxian still didn't believe it, and said: "In two hours, I can't even finish the number of rounds." Do you know how to analyze phone numbers?"

Guo Qian nodded, but shook her head again and said: "Our switch does not have a long-distance circuit for the time being, and is only responsible for connecting the phones in our mine, and there is no need to analyze the number of long-distance incoming calls at all, nor do we need to conduct number analysis for long-distance outgoing calls." I'd really like to give it a try, and now I can only do some simulations at night with a human switch. …… Two hours is enough for him, and I don't need five hours either. If you don't believe me, we can give it a try now, Zhu Jianhua and I have tried it many times, and it takes him more than eight hours. ”

The so-called phone number analysis means that the switch analyzes the phone number after receiving the phone number from the telephone user to determine whether it is a local call or a long-distance call, and if it is a long-distance call, it has to analyze which direction it is. For example, if the switch receives a 01023456789 number from a user, and the switch receives the first 0, it will judge that it is a long-distance call, and then analyze the second digit. If the second digit is 1, the call will be judged to be a call to the capital; if it is 2, take two digits to analyze which municipality it is directly under the central government (note: at this time, the long-distance area code of the capital is still 01, not 010 added later); if the second digit is other than 1 and 2, then take three digits for analysis, and then send it to the corresponding long-distance transmission equipment, which will send it to the corresponding long-distance transfer bureau (such as the Beijing long-distance transfer bureau and the Shanghai-Hai long-distance transfer office).

But. But like the Red Star Coal Mine Switch, it is very simple, as long as it is not a call to the mine, it will be cut off, because it has no relay out circuit for the time being.

"Ahem!ahem...... , I believe, I believe......" Ling Guxian said as he walked out of the computer room, and when he got out of the computer room, he said, "Director Gao, let's go, go back!"

Although he said "I believe" in his mouth, his face was gloomy and terrifying.
