Riding the wind of rebirth

"This series of changes has made the 10,000-line large-scale programmable digital exchange stand out from the plight of being ignored and become the focus of much attention."

“Just when everything was moving in the right direction, there were suddenly voices within our system questioning the project and even suppressing it.”

"Afterwards, under the instigation of some people with ulterior motives, after we completed the self-test, the Post and Telecommunications Industry Corporation was forced to terminate the project on the grounds that it was 'involved in unplanned areas'. The general manager and deputy general manager of the company were also held responsible and removed from their positions!"

"In September of the same year, those people reconvened some experts and teams and conducted rigorous technical tests for a month and a half, aiming to completely negate our identification results."

"At the appraisal meeting in November, they tried to downgrade this achievement from internationally leading to domestically advanced."

"This practice was seriously criticized by several academicians. In the end, the director of the appraisal committee took full responsibility and imposed penalties. Then a new expert group was reorganized to re-appraise the 537-port digital program-controlled switch produced by Luoyang Factory 04, designated as HJD."

"In December 1991, the Ministry of Posts and Telecommunications convened more than 12 expert representatives to issue a technical appraisal report on the HJD150 04-line program-controlled digital telephone exchange. After rigorous evaluation, the exchange had a capacity of 6 lines, and its overall technical level was comparable to that of the late 80s. In addition, it adopted innovative technologies in system structure and switching network, and its call processing capability reached the international leading level, marking a major progress in my country's modern communication technology."

"Thus, after the dean of the Military Information Engineering College, Lao Wu, and 15 young people spent 17 months and 6 million to develop the 10,000-port digital program-controlled switch with our own intellectual property rights, it finally passed the appraisal!"

"Afterwards, my country announced this news to the outside world, declaring that my country's modern communication technology had made a major breakthrough, breaking the long-term monopoly of the 'Seven Countries and Eight Systems' in China's program-controlled switch market, and also ending the 'Paris Coordinating Committee''s embargo on large program-controlled switches imposed on my country since 1989. This achievement not only broke the Western world's propaganda that China could not produce large-capacity program-controlled switches on its own, but also had a far-reaching impact internationally."

"HJD04 not only broke the foreign monopoly, but also broke the world record of busy-hour processing capacity held by Siemens of Germany by nearly three times. It is still the fastest switch in the world. Foreign media even called it an 'atomic bomb' dropped by my country in the field of information and communication technology and industry. After inspecting our experimental results, the foreign general manager of Bell Company was shocked and predicted that 'the future will be dominated by 04 machines.'"

"Such a good thing was almost strangled in the cradle?!" Zhou Zhi was really shocked and angry.

"It's not that they will be strangled. After all, we old guys are still here and we can't tolerate them not being realistic." Old Yu was more open-minded: "Although there are some twists and turns, conspirators and clowns will never see the light of day."

Academician Sun was not as open-minded as Elder Yu. He shook his head and said, "If you hadn't seen the faces of those people at that time, you wouldn't have understood the value of your attitude, Elbow."

The blind pursuit of foreign scientific and technological achievements, or worship of foreign things, has almost become a disease in today's technology community.

As a latecomer, Zhou Zhi experienced the process of watching those so-called unattainable "industrial pearls" being plucked one by one.

So much so that in later generations, those big-breed anti-China people would ridicule China as long as it was not leading the world in some aspect, as if they were the group that hated China the most.

The funniest thing is the so-called "Even if I give you a Canon lens, you still can't make it even if you take it apart."

In fact, the American Eagles don’t have brand-name lenses, and the Russian Bears don’t have brand-name lenses either. In the eyes of the big breeders, “they have their own national conditions.” But when it comes to China, it’s “you can’t do it, you’re useless.” The double standards are clear. Of course, these people’s faces have been slapped again and again in later generations, because China’s speed of picking pearls is too fast for them to keep up, and finally they are forced to narrate according to the logic that “China needs to produce everything in the world to win.”

Sometimes Zhou Zhi himself finds it funny. According to their standards, it seems that these people are absolute supporters of China. Compared with their arguments, he seems not patriotic enough...

Seeing Zhou Zhi's playful and sarcastic smile, Mr. Sun felt particularly relieved: "The 04 machine has excellent military quality. Since it was put into large-scale production, it has made great contributions to the domestic substitution of our military communications. Now is the key node for the transition from military to civilian use. Elbow, this is a good thing for everyone, and I hope you can help greatly."

"Let's wait until Old Wu comes. He can explain the 04 machine more clearly." Old Yu said: "Upgrading the 04 machine to a larger-capacity fiber-optic programmable switch is also a key project, and now is the critical period for tackling the key issues."

"Fifteen people, six million, one and a half years..." Zhou Zhi turned his head and looked at Mai Xiaomiao: "Xiaomiao..."

"Compared with Grandpa Wu, we should be ashamed." Mai Xiaomiao said with a smile: "Elbow often complains that my project is a furnace that burns money..."

“Hahahaha, let’s not argue with him.” Old Yu now dared to joke with the two juniors: “Different projects, different investments, and different results. Some results can be used to make plows, and some can be used to forge swords. We can’t generalize!”

"Yes, Xiao Miao, hurry up and teach us. When Lao Wu comes over in the afternoon, we can help you to shoulder the burden for him!" Old Sun said with a smile, "Otherwise, he will rest on his laurels from the achievements of the 04 machine!"

So the content of today's class has been changed. Originally, after the general introduction, we were going to start with computing power neurons, but now it has been adjusted to first talk about the network architecture and exchange protocols, as well as the algorithm principles of data dispersion and concentration.

Zhou Zhi could still participate in the first part, but when it came to the principles of algorithm models, Mai Xiaomiao began to extensively cite advanced mathematical statistics, discrete mathematics and many other tools, and Zhou Zhi felt like he was reading a book written in heaven.

On the contrary, the eyes of several old academicians such as Yu and Sun became brighter and brighter, and the way they looked at Mai Xiaomiao became more and more fond.

Zhou Zhi didn't understand the lessons, so he just watched from the side. After a morning of lessons, Zhou Zhi felt that if Mai Xiaomiao said he wanted stars, the elders would say, "Xiao Miao, let the grandfathers think of a way. I guess it shouldn't be a big problem..."

This is a kind of mutual appreciation and care among scientists. Zhou Zhi guessed that it was similar to how Grandpa Wang and Grandpa Qi treated himself.

After just one class in the afternoon, Mr. Wu had already arrived. There was one more person who cared for Mai Xiaomiao.

After hanging up the phone, he booked the next available flight from Zhengzhou. Although Zhou Zhi was the rich man who could invest, he was obviously more interested in the communication principle designed by Mai Xiaomiao. After entering the meeting room, he didn't say any more nonsense and started discussing the design ideas of the fiber optic switch. (End of this chapter)
