What Song Yuanchao did before, what he did when he returned to Shanghai, and what he is doing now, Uncle Li knows very well.

Judging from the life trajectory of Song Yuanchao, he has never been exposed to these. Although there are many young people in the society who have a hobby of electronics, and there are a large number of subscriptions to folk electronic books, ordinary electronics enthusiasts often go to the place where Huhai monopolizes electronic components (old electronic market) to purchase some secondary tubes, tertiary tubes, resistors and other parts, and assemble radios or something according to the content taught in the books after returning home.

These hobbies were all the rage in the early eighties, and they also produced many folk masters. But the problem is that I haven't seen Song Yuanchao toss these at all, besides, the continuation device sounds ordinary, but many people who are not experts will think of the relay as their first reaction when they hear it, so they regard the continuation device as a kind of relay, but in fact, these are completely two things.

Song Yuanchao not only knew what an access retinator was, but what surprised Uncle Li even more was that Song Yuanchao also mentioned a program-controlled exchanger, which is definitely not something that ordinary electronics enthusiasts can understand, which cannot but surprise Uncle Li.

"Oh, I heard the professor say it in school before, and I can't remember anything specifically, but I just remember that the access renewer is an important part of the program-controlled switch." Song Yuanchao casually found a seemingly reasonable reason, but Uncle Li didn't continue to ask, Song Yuanchao is a college student at Beijing Normal University, and there is a hidden dragon and a crouching tiger in the university, maybe there is a professor who specializes in this aspect.

Song Yuanchao saw that Uncle Li didn't continue to ask, and his heart eased. He blurted out completely subconsciously just now, and when Song Yuanchao said it, he realized that he had missed his mouth.

Song Yuanchao is indeed not an electronics enthusiast, let alone any research in this area, as for what the professor said that this is even more nonsense, it is simply a reason for Song Yuanchao to find casually. The real reason is very simple, it is because of Song Yuanchao's work in his previous life, so he understands this.

In his previous life, Song Yuanchao returned to Huhai to work in the telephone bureau, although he was only a temporary worker in line work at the beginning, and he did the work of climbing telephone poles every day. But as Song Yuanchao slowly changed from a temporary worker to a regular worker, and became the head of the construction team, Song Yuanchao began to come into contact with some technical work.

Later, Song Yuanchao went to study at the night university, got a diploma from the night university, and gradually improved his position in the telephone bureau, first from the line to the field management work, and then to the administrative management, and when Song Yuanchao was about to retire, he was already the middle-level leader of the Shanghai and Haihai telecommunications department.

In the past ten years from the 80s to the 90s, it was an era of rapid development of China Telecom (telephone), especially the rapid expansion of telephone lines, which changed the situation that telephones were difficult to install and expensive before. The reason for this change is because of the improvement of technology, including the update of hardware technology.

For the telephone, with the new generation of program-controlled switches replacing the old equipment, the telephone line has been expanded, so that the previous constraints of the line shortage and semi-manual exchange mode have been greatly improved, thereby accelerating the development of domestic telecommunications.

Song Yuanchao has experienced this era, and at the same time, after being transferred from the line service post to the management position of the machine maintenance post, he was directly responsible for the installation and commissioning of equipment as a basic cadre.

Although Song Yuanchao does not understand the technical principles of these products, he knows the use and installation requirements of these products, and even some simple maintenance.

From this point of view, it is not uncommon for Song Yuanchao to know what an entry and exit repeater is, and to understand what this thing is for.

But Song Yuanchao never thought that the new product proposed by Uncle Li was actually an entry and exit repeater, which really surprised him.

According to his memory, the first large-scale program-controlled exchanger to be imported in China was Rongcheng.

In December 1980, Rongcheng signed a contract with Fujitsu to introduce the F-150 program-controlled switch system, and in November 1982, that is, at the end of this year, China's first 10,000-door program-controlled switch will be opened in Rongcheng, thus opening the prelude to the popularization of telephones in the country.

In the following years, other cities began to learn from Rongcheng to introduce and install program-controlled switches, and in just a few years, a large number of imported program-controlled switches were purchased by local telecommunications departments.

Although the imported program-controlled exchanger is easy to use, it is expensive, so this has led to a large loss of valuable foreign exchange in the country.

It is precisely because of this situation that the relevant ministries and commissions have made self-reliant instructions and required the development of their own program-controlled switch equipment to replace imported products.

In 1986, the relevant departments dispatched a group of elite soldiers from Chang'an's 619 factory to Pengcheng to develop program-controlled switches in Zhongxing Semiconductor Company, which had just been established in Pengcheng.

In 1987, in less than a year, the research and development team successfully developed a program-controlled air separation switch. At the end of 1989, the first ZX-500 digital program-controlled switch independently designed and developed in China came out, and in 1991, it won the first prize of the Ministry of Aerospace Science and Technology Progress Award.

This is the history of the development of China's program-controlled switches, as a former industry person, Song Yuanchao is very aware of this process, and has personally witnessed and experienced this era of development.

Suddenly, Song Yuanchao remembered one thing, in his previous life, Song Yuanchao did not meet Li Daqi after returning to Huhai, because he didn't know where Li Daqi's family had gone after being kicked out of the small western-style building. But now it's different, he met Li Daqi soon after he came back, and the two friends who grew up together when they were teenagers reunited, leaving no regrets in their previous lives.

If according to the original development, Li Daqi did not meet the Song Yuanchao, as a young man who returned to the city, Li Daqi could not find a job in Shanghai at all, just because he was invited by his comrades-in-arms to go to Yangcheng, and then went from Yangcheng to Pengcheng, so as to settle down in the south and become a successful entrepreneur from scratch.

Soon after Li Daqi went to the south, Uncle Li's family also followed, and Li Xiaoyun was definitely not admitted to Beijing Normal University as she is now, but probably went to Yangcheng University. As for Uncle Li, he has been sent to work in the workshop while losing his old house, which has made Uncle Li disheartened for so many years, and Aunt Dong is about to reach retirement age.

Li Daqi's family went to the south at that time, and the calculation time should be about this time, although the current Uncle Li is no longer young, but he is in his early 50s and has not yet reached the time of retirement. When I arrived in the south, Uncle Li's character must have been unable to stay at home, and at that time, it was also the time when the development of the south, especially Pengcheng, was Xunmeng, and with Uncle Li's profession and title, it was easy to find a good job as a rare talent.

Thinking about it this way, maybe Uncle Li worked in an electronics factory in Pengcheng or Yangcheng at that time, and then went to work in ZTE Semiconductor Company. At that time, ZTE Semiconductor Company undertook the research and development of domestic program-controlled switches, and was able to make a program-controlled air separation switch in the first half a year, and then designed and developed the first ZX-500 digital program-controlled switch in two years.

Thinking of this, Song Yuanchao's heart couldn't help but feel a little hot, if all this was true, then this would be incredible.

How much is the profit of the program-controlled switch, Song Yuanchao knows better than anyone that the price of the Fujitsu F-150 program-controlled switch introduced by Rongcheng is about less than 3 million US dollars, and the reason why Fujitsu is chosen is because Fujitsu's offer is the cheapest.

"High in the Sky"

Compared with the quotation of other companies, Fujitsu is only less than half of the quotation of several other companies, you must know that the highest price of the same 10,000 doors program-controlled switch price is as high as 6 million US dollars, under the huge price advantage, Fujitsu's such a "low" price is naturally the first choice.

Although the price is relatively low, it is also relative, Fujitsu has already made a lot of money on the price, and the real cost is lower. In addition, it is a contract trap for the introduction of equipment, Dongying people's equipment is sold cheaply, but the follow-up service, maintenance, etc. are very high, so that after a few years, the general ledger actually pays more money than the Western companies with the highest quotation at the beginning, and the general ledger is more than worth the loss.

ZX-500 digital program-controlled switch in 1987 sold at about 60,000 yuan, you must know that this is only a small 500-door digital program-controlled switch, from this point of view this price is already very high.

In 1991, 04 machine, that is, the first domestic independent 10,000-door program-controlled switch was born, with the emergence of this program-controlled switch, foreign brands fell sharply, thereby greatly reducing the cost of equipment procurement.

In addition, at that time, due to the vast market and huge profits, before the nineties, the domestic large-scale program-controlled switch market was monopolized by foreign products, and there were a total of seven countries' products, and the products of these seven countries were divided into eight systems, so they were nicknamed "seven countries and eight systems" by industry insiders.

This situation has also led to the different systems in various regions of the country, resulting in inevitable chaos. In addition, because of the high cost of the product and the need for foreign exchange imports, in order to make up for the lack of funds, it has led to the "initial installation fee" product of the telephone.

The initial installation fee was initially about 5,000 yuan, then gradually reduced to about 4,000 yuan, and then to 3,500 and 3,000 yuan after a few years. It was not until the mid-to-late nineties, with the continuous advent of self-developed program-controlled switches, that the cost of equipment dropped sharply, and the so-called initial installation fee was slowly abolished.

"Uncle Li, are you still there?"

"What's the matter? Are you interested? Uncle Li said casually, he just thought that Song Yuanchao would ask casually, but he didn't expect Song Yuanchao's next sentence to make him stunned.

"If it's convenient for you, can you show me this information?" I think you have a good idea, and if it can't be realized in the current unit, there may be other units interested in it. You know that I am studying at Beijing Normal University and know a lot of experts, I would like to bring your information to them, do you think it is appropriate? ”

"It's ......." Uncle Li didn't expect Song Yuanchao to be really interested, and after thinking about it, he felt that what Song Yuanchao said was also reasonable, since the old unit was not good, his hard work couldn't be left to accumulate dust, right? That's what he's been working on for years! It's too polite to put it on.

"Okay, you can come to the house tomorrow to get it, and I'll tidy it up when I get back." Uncle Li immediately nodded in agreement, and seeing that he agreed, Song Yuanchao shook his fist fiercely, I didn't expect it to be so easy!
