"Mr. Director, why don't you buy the program-controlled ones?" Cao Changjiu finally couldn't help but speak, in his opinion, even if he had to import them, he had to buy the most advanced ones, and it was better not to buy those that others had eliminated like this.

"Who is this?" The leader was a little strange, the young man didn't speak along the way, and thought he was Dr. Yu's follower.

Dr. Yu hurriedly introduced: "This is my partner, surnamed Cao. ”

"Little comrade, you are really joking, even the Japanese themselves do not have program-controlled switches, where can we buy them. The leader laughed.

"Then we can't make our own program-controlled switches, so we have to buy second-hand goods from the Japanese?"

"Isn't this quite new? The director's face was a little unbearable, "It's not that we just want to buy Japanese second-hand goods, it's just that it's cheap, and second, we can use it to study imitations." ”

"Then there's no need to buy this outdated model imitation, just jump to program control. "I've been haunted by this for a long time.

"Little comrade, the program-controlled switch can only be provided by Bell in the United States at present, and you know how much money the program-controlled switch devil has opened for us. ”

"I don't know. "This is very honest for a long time, I don't know it, I don't know.

"$800 a line, a 10,000-line bureau program-controlled switch will cost more than 8 million, not counting the installation, commissioning, maintenance and parts, the total will be more than $10 million. The leader also seems to be helpless, "The program-controlled switch is a new technology and new product, and we have not used it." Who would dare to use something new with such a big investment? Besides, a local switch can cover an area of 20 square kilometers at most. ”

Dr. Yu was also a little moved: "Even if the country wants to buy it, the Americans will not sell it, and there is such a clause in Batumi, which embargoes switch technology." ”

"Doesn't this mean that unless we don't want to buy the most advanced, we can only be slaughtered by others?"

Why is it the way it is now, and something must have happened in the future.

In my long-term dream, I once took over private work, of course, not to develop switches, but to write software for switches. He remembered that the domestic switch market was very prosperous at that time, there were almost no foreign brands, and the price of each line was only 30 or 40 US dollars.

It is necessary to understand the market, and there has been a little vague feeling for a long time.

If the long-term plan is to open up the market and work hard with those predators, then entering the communication market to develop switches is a profitable business, which is state procurement.

For a long time, I didn't understand the market of program-controlled switches, and it seemed that only Americans could do it. But it will definitely become popular in the near future, because the Japanese will be able to sell vertical and horizontal switches to the Chinese people, indicating that they are also upgrading.

There are very few telephones in Huaxia in 79, and there are no phone numbers with more than 6 digits in the whole of Huaxia. For a long time, I had to call Beijing, and I had to run to the telegraph office, and the call quality was very poor and the line would be disconnected, and I was depressed.

"Little comrade, you have to eat the rice one bite at a time, how can you do it in one step. The leap forward is indeed attractive, but it is also necessary to respect the laws of science. "The leader has been silent for a long time, so he is angry.

Chang also withdrew from thinking, and said embarrassedly: "I'm sorry, my words are too heavy." Mr. Director, I have a request, and I don't know where it is inconvenient. ”

The leader didn't care: "Say, if there is any difficulty, we will try to help." "Chinese people are still very polite to foreigners.

"Do you have technicians here, especially switch technicians, and I'd like to talk to them. I also studied technology and wanted to contribute to the development of the country. "I have been thinking about the words for a long time, for fear that the leader will misunderstand.

"That's fine, we're welcome. The leader didn't have the slightest suspicion, and directly explained a few words to the followers, "Or let's have a meeting to communicate?"

"No, I just want to learn, and I don't have to be so excited, hehe. ”

"Okay, Xiao Li, you take this little comrade to the technical department. The leader arranged directly, "Mr. Yu and I are in the office, just come to us after you are done." ”

"Thank you, Director. ”

Originally, the Shanghai Telegraph Bureau also undertook the task of developing switches under the planning system, and the main direction of attack was various interface circuits and relay circuits.

After discussing with the technicians for a while, Rao has a long understanding of the circuit and listens to the big head, after all, analog circuits and digital circuits are very different.

But the principle has been understood for a long time, and the function of the switch is nothing more than to connect the lines of two users for talking, but the previous stepper system is manual wiring (that is, the kind that people see on movies and television with plugs plugs and plugs), and the vertical and horizontal system is wiring with relays (a little mechanized).

As for the program-controlled exchange technology, the technical staff of the telegraph office also did not know anything about it, but they only knew that it was controlled by a computer, and it was extremely advanced.

Nonsense, scolded for a long time, and then I know that the program-controlled switch is computer-controlled, and it is also a technician.

There was no way, so I had to return with a stomach full of terms and imagination for a long time.

After finding Dr. Yu for a long time, the two returned to the hotel after dinner.

"You don't really want to make switches, you can't just buy a few parts and put them together. "Dr. Yu is a little confused.

"It's okay, I'm not a self-conscious person, but I'm just a little excited by the profits in this field. Chang Chang smiled.

"That's good, we don't have that much money to burn now, so we can only take it step by step. Dr. Yu nodded.

"We don't have the money, but the state does. "It's weird to laugh for a long time.

"What do you mean?"

"Catering to the market, if the country needs it, we will ask the state for money. ”

“？？？”

"I'll tell you when I think about it. ”

“......”

Cao Changzheng's wishful thinking, if the country was a high-accumulation development policy before 79 years, then after the reform and opening up, it will be high-speed development.

Focusing on economic construction means infrastructure construction, and the current communication equipment is certainly not suitable for development.

The long-lasting keyword of the 90s was mass breakthroughs, and it was a crazy time.

Reform and opening up, foreign switch manufacturers are like sharks who have asked the smell of blood, and have poured into the Chinese market, taking advantage of the naïve psychology of the so-called economists in China, and selling all kinds of program-controlled switches to Huaxia at high prices in a way that is almost dumping.

At that time, the equipment in the Huaxia communication system could be described as a Wanguo brand, and there were four words that were well said - "seven countries and eight systems".

That is to say, there are at least seven or eight countries in the system, and N standards coexist, which greatly increases the complexity of the system.

What is more, the Japanese are also vainly trying to control the telecommunications market in China and suppress other manufacturers by dumping them at low prices.

The chaotic market has caused distress to the Chinese authorities, and on one occasion the communication between Beijing and Shanghai was cut off for 24 hours because of these reasons. The Japanese are also very scheming, the host is sold cheaply, and the accessories are sky-high prices, and you have to buy them.

Therefore, people of insight in China began to reflect on whether such a policy should be continued.

Since 89 years, foreign switch equipment has not been able to enter at all, which has hit most of the people who pursue the market for technology.

In view of the huge profits in the switch market, some manufacturers have participated in the research and development, or joint ventures or private enterprises, the most famous is the 04 machine.

At that time, there was a very market argument, that is, it was better to buy and buy than to rent, as long as the market was opened to foreign capitalists, technology would follow.

But reality shattered their dreams, and the blockade remained the same, and it intensified.

In 91, Wu Jiangxing, president of the People's Liberation Army Information Engineering College, presided over the development of HJD04 (referred to as 04 machine) 10,000-door digital program-controlled switch, thus breaking the prediction that "Chinese cannot build large-capacity program-controlled switchboarding" in one fell swoop. Zhu Rongji, then Vice Premier of the State Council, spoke highly of HJD04: "What the 04 machine sent was a fresh breeze. ”

This was a terrible thing at that time, 10,000 doors program control is a hurdle, only foreign countries can be developed, the emergence of the 04 machine immediately caused an earthquake in the industry, and its success from development to industrialization is even faster and amazing, the whole army's communication network has been replaced with 04 machine.

After 95 years, a number of private manufacturers appeared, successfully developed large and medium-sized program-controlled switches, and there was a "group breakthrough", and the more successful ones were Julong, Datang, Huawei, ZTE and Jinpeng.

At that time, the "huge golden China" five golden flowers forced foreign manufacturers in the Chinese switch market to withdraw, no competition at all, the original 300 ~ 500 US dollars of the first line of the local program-controlled switch sold to 98 years of 50 US dollars of the cabbage price.

Cao Changkong has the ability to see the future, but he is embarrassed by the fact that the funds cannot enter, which is really a regret in life, and he can't help but have a crooked idea.

Dr. Yu thought that there would be such a long time to have such a fancy, he is still worried about how to continue the career of the two people, the current funds are completely supported by the sale of microcomputers, fortunately, the domestic demand is also quite large, nearly 200 microcomputers have been sold, and there are millions of profits.
