Jiang Xinwei also thinks that he is a little forward-looking, but can he not be cautious in the face of such a major event that affects the lives of dozens of miners?

Listening to this technician's words, he couldn't help but retort loudly: "You are still a technician, who dares to pat your chest and guarantee if you don't know the fault situation? Now I only hear you say that the phone is broken, but how do you know whether the broken equipment is a switch, a transmission device, or a power supply device? Even if you know that it is a switch, the switch is divided into manual, step-by-step, and vertical and horizontal systems.

The technician was dumbfounded by his words, because he didn't understand what Jiang Xinwei said, such as what he said, such as switch, transmission equipment, stepping system, vertical and horizontal system, etc., it was simply too lofty: What is that?

He shut up, but the eyes of Mine Chief Guo and the others lit up.

They don't actually understand this, but in their opinion, it is certainly not easy for people who can say so many professional terms with their mouths open, and they must have some skills.

Thinking that the lives of the more than 40 miners trapped in the mine were in danger, Mine Manager Guo said categorically: "Okay! The telephone maintenance will be handed over to you, and all the people in the computer room will obey your command until the maintenance personnel are sent by the superiors." ”

As he spoke, he turned to Zhang Guohua and said, "Mine Chief Zhang, you are old, don't go to the mine to rescue the emergency, stay at the headquarters on duty." If there is any problem at the rescue site that needs to be broadcast, and what news needs to be released, you will announce it on my behalf in the broadcast studio. ”

Mine Manager Guo was very steady, and although Jiang Xinwei was allowed to try to repair the phone, he gave him a limited time: as soon as the maintenance personnel sent by the superior arrived, you had to hand over the maintenance work. Moreover, he also arranged a "supervision army" for Jiang Xinwei, and in the name of needing to publish news on the radio station, let Deputy Mine Director Zhang keep an eye on Jiang Xinwei and not mess around.

The communication room is on the ground floor.

When following Zhang Guohua downstairs, Jiang Xinwei was quickly recalling what he had read about China's telecommunications equipment in the 90s.

He knew that the "phone was broken" in the mouth of the mine leader did not just mean "the phone was broken," but a general concept for telecommunications laymen, and the meaning expressed was that the phone could not be called.

But people who have a little understanding of telecommunications technology know that there are many reasons why the phone cannot be called, it may indeed be that the telephone is broken, or it may be that the telephone line (user line) connecting the telephone and the computer room is broken, and it is more likely that the telecommunication equipment in the computer room (mainly the three major parts of the computer room, such as switch, transmission equipment, and power supply equipment) is broken.

The speed of the two was very fast, and Jiang Xinwei reached the first floor before he remembered how many things.

As soon as he approached the door of the computer room, he heard a middle-aged man inside anxiously asking, "How is it, Qianqian, you are a high school student, can you fix it?"

Soon a girl said in a crying voice: "Squad Leader Li, I don't know how to repair, I haven't studied in school." …… , My dad went to find someone, and the maintenance staff of the post and telecommunications bureau will come soon. ”

The middle-aged man, squad leader Li, muttered, "Who knows when the post and telecommunications bureau will come?...... , hey, it's useless to go to high school, it's better than me, a junior high school student......"

Jiang Xinwei walked into the communication room, a smell of burning plastic came to his face, the entire communication room was shrouded in faint smoke, and the usually dazzling incandescent lamp turned into a yellow duck pear at this time.

He involuntarily covered his nose and asked loudly, "What equipment is broken?"

"Switch!" a young man blurted out.

Finally saw the equipment in the computer room clearly, and when he heard this answer, Jiang Xinwei breathed a sigh of relief: Fortunately, the switch is bad.

What is a switch, simply put, is a device that switches calls, and all landline telephones must be connected to it in order to make calls. It connects you based on the number you dialed out. At first, there were manual switches, then step-by-step switches, then vertical and horizontal switches, and finally digital program-controlled switches.

Jiang Xinwei is fortunate because the switch used here is the most primitive manual switch. In the previous life, when they first entered the University of Posts and Telecommunications, the teacher took them to learn it, because it is simple and easy for students to understand its principle. Invented more than 100 years ago, this switch is as simple as having only two main circuit boards inside it and no complex mechanical parts.

Jiang Xinwei, who had confidence, said to the people in the computer room: "I am the maintenance personnel invited by Mine Manager Guo, and he appointed me to be responsible for telephone maintenance, and you all have to obey my command." Now, I command you all to stand aside!"

"Ahh

Squad Leader Li was even more surprised and asked loudly: "The telecommunications bureau is coming so quickly, is it impossible?"

Jiang Xinwei strode into the computer room and asked loudly, "Is the power supply outside cut off?"

Another young man hurriedly replied, "Cut off!"

Approaching the artificial switchboard, Jiang Xinwei couldn't help but take a breath of cold air: Where is this switch, it's just a pile of blackened garbage, and there is a faint black smoke in some places.

He commanded in a loud voice: "Whoever, give me your test pens, multimeters, and other spare parts at once!"

At the beginning, the people here didn't pay attention to Jiang Xinwei's appearance, and they were greatly relieved to see someone coming to take over the repair. But when the smoke was blown away by the wind outside, someone saw Jiang Xinwei's face clearly, and suddenly had doubts.

The young man was the first to attack and asked in disbelief: "Hey, are you really a maintenance worker sent by Mine Chief Guo? Are you twenty years old? How can you be a maintenance worker?"

Squad leader Li even recognized Jiang Xinwei, and couldn't help but say loudly: "Impossible! You can't fix the phone." I've seen you, you're the new postman at the Shiqiao Town Post Office, aren't you?...... Hehe, you think we are all laymen, and we can't even tell the difference between telecommunications and postal services. Can't fix it! Can't let him fix it......"

Obviously, because of his work relationship, he has dealt with people in the telecommunications department of the Post and Telecommunications Bureau, so he has some understanding of the internal situation of the post and telecommunications industry, and knows that post and telecommunications include the two industries of post and telecommunications.

Before the words fell, only a crisp sound was heard, and squad leader Li fell to the ground and let out a miserable howl.

Jiang Xinwei glared at his eyes and shouted: "Fart! Are you smart or Mine Chief Guo smart? You all allow me Jiang Xinwei to fix it, what kind of bullshit are you talking about a little broken squad leader?" Get out!"

It was only at this time that Jiang Xinwei realized that the guy who crossed the possession seemed to be a little too bloody, and if he didn't say it well, he was very impulsive, and he was angry in both words and actions, no wonder he was expelled from school.

However, he didn't think this kind of character was a bad thing, but was a little happy: now that people's lives are at stake, how can they have time to talk to them?

Jiang Xinwei's "atrocity" had an immediate effect, and it shocked the people in the computer room who doubted him, especially when he played the sign of the mine manager, no one dared to question whether he was a fox and a fake tiger.

Zhang Guohua, who was standing in the corridor, also frowned, but didn't say anything, just watched quietly.

The young man quickly found the multimeter, cross and other spare parts, and politely sent them to Jiang Xinwei.

The beaten squad leader Li covered his face and left, and when he left, he didn't forget to glare at Jiang Xinwei, his eyes were full of viciousness and resentment. When he saw Zhang Guohua in the corridor, he didn't say hello: he even hated this leader who didn't say anything to stop Jiang Xinwei from beating people.

Jiang Xinwei ignored him at all, but buried his head in carefully checking the switch.
