Although the vertical and horizontal switch can support 1,800 telephones, which is enough for internal calls in counties or large enterprises, it is still far from enough to support one city!

A switch that can control tens of thousands of telephones can only be a program-controlled switch.

However, the export of high-end program-controlled switches is restricted, and telephone offices in various places can only find their own solutions.

As a result, the domestic market fell into a state of seven countries and eight systems in the 1980s.

There are a total of 8 models of models, among which Toyo's NEC and Fujitsu have two models respectively.

These standards come from seven countries respectively. In addition to Japan, they also include Gaul's Lucent, Switzerland's Ericsson, German Siemens, Belgium's BTM, and Gaul's Alcatel.

In addition to being expensive, it is also because according to the regulations of the Batumi Alliance, outdated switches can only be sold domestically, so I am not willing to sell them and charge sky-high prices.

Because during this period, with the development of chips, the upgrade speed was extremely fast.

Unscrupulous foreign businessmen often take advantage of domestic technology ignorance and sell backlog products from four to five years ago as the latest models, resulting in a large loss of foreign exchange.

It was not until 1994, when switches such as Julong Group's HJD-04 switch, ZTE's ZXJ10, Datang's SP30, Warwick's CC08, Jinpeng's EIM601, and Southern Telecom's HAX-SP1 appeared, that domestic telephone companies got rid of this problem.

Finally, the four giants of the communications industry, "Great China", were formed, namely Julong, Datang, ZTE, and Warwick.

Li Sanbiao is familiar with this 20-year unbearable history in the communications industry.

Basically, it was suppressed by foreign businessmen, and the biggest reason was that there were no domestic brands that could shoulder the important task of national communications.

If we directly develop a program-controlled 10,000-door switch now, we can take advantage of the fact that local telephone offices do not have such large purchasing powers and exclude foreign companies from the Longguo communications market in advance!

Li Sanbiao thought seriously.

His cooperation partner is a large factory like 738 Factory. If he captures all the market in Beijing, it will naturally have a strong demonstration effect!

What is most beneficial to him is that communications between various places and the Four-Nine Cities are never allowed to be interrupted!

In the original timeline, Sijiucheng finally adopted the cross-horizontal switch from the 738 factory. Although it was backward, there was no incompatibility problem.

There are seven countries and eight systems across the country, with various models, but the interfaces are incompatible with each other.

Communications between telephone offices in various places soon fell into chaos, and it was difficult to get through the calls of high-ranking foreign officials.

Among them, the situation in Zhejiang Province is the most outstanding. The telephone offices in the province have put together all kinds of products from various countries, which can be called a living museum.

Even neighboring counties within the province often have difficulty communicating normally due to standard interface conflicts.

The foreign businessmen who came to invest left Long Country directly because they couldn't get through the phone for two hours.

Although there are no serious consequences of being monopolized by a single manufacturer, the price paid is also painful.

And if the telegraph building in Forty-Nine City takes the lead in adopting his system, most parts of the country will follow!

The two neighboring provinces have different standards. Even if the communication is interrupted, they can only blame each other. And if the communication with the telegraph building is cut off, the telephone exchange will definitely have to suffer.

In this way, if someone wants to use imported products, they must consider their own future, and the seven-nation-eight system will naturally become impossible.

Li Sanbiao had made up his mind and said to the 738 factory director: "I can provide you with advanced chip and switch design drawings, but you have to send a few technicians to Warwick to provide guidance in person, so that Warwick can build tens of thousands of switches within half a year.

."

The director of Factory 738 was overjoyed and nodded repeatedly.

Li Sanbiao continued: "However, after giving you the technology, our output in Warwick will definitely not be as high as yours, so we focus on the southern market, and you can't compete with us."

"We need to jointly develop a communication system that is compatible with the existing seven countries and eight systems in the world, but their domestic versions are not compatible with us!"

"Next, you have to convince the Telegraph Building to use our machines!"

"Finally, we will sell them at one-third of their price and replace the existing imported equipment. From now on, we will exclude all existing foreign replacement equipment!"

Several directors of Factory 738 were all dumbfounded by what Li Sanbiao said.

They are still producing according to the planned instructions without thinking too much about it. They don't care what kind of products the telephone exchange uses.

But after Li Sanbiao spoke, their minds immediately sobered up!

Yes, that’s it!

They simply want their products to reach foreign standards, but they don’t actually consider why they do this!

In the past, the domestic market was not big, and catching up with foreign countries was mainly to prove that Longguo was no worse than others.

But I never realized how much economic benefits it would bring after reaching it!

If it fails to do so, it will cause great losses to the country and itself!

Li Sanbiao continued: "The seven-nation-eight system created by the Batumi Agreement is a key factor that leads to poor communications in our country and affects foreign investment in our country!"

"Therefore, we must overcome this technology. The benefits it brings are not only as simple as saving foreign exchange, but also bringing countless investments!"

"Time is life, efficiency is money, we will start research and development now! Prepare your people immediately and set off for Shencheng tomorrow!"

The leaders of Factory 738 were in disarray. They sent guards to search Li Sanbiao's sales department and kidnapped Li Sanbiao, just because they were afraid that he would not agree.

Unexpectedly, this Li Sanbiao was actually more active than me. It looked like he was taking advantage of me. Who kidnapped whom?

But he took the blame first, and Li Sanbiao fully accepted his request, and could only uneasily accept his request for cooperation.

Li Sanbiao did not break his promise and entered the research institute of Factory 738 in the name of research.

In addition to communications, 738 is also a computer research institute, which stores a large amount of cutting-edge information on computers and communications technologies of this era, and ordinary people are prohibited from getting involved.

Because radio and television equipment is also produced here,

Including a large number of broadcast medium wave, long wave communication technology, and satellite communication technology, with the core data of Longguo radio and television technology.

Li Sanbiao was not polite and scanned each of them one by one with the three uncles.

Even the top three supercomputer masters do not have corresponding details about these technical secrets.

Li Sanbiao was overjoyed. If he wanted, he could even get a signal by himself and send it to the world via satellite.

It can also receive signals from most satellites around the world.

The director of 738 coughed twice, feeling that Li Sanbiao had seen too much.

Li Sanbiao smiled and said: "I am just visiting, so I am not so stingy, right? I will draw you the circuit diagram of Wanmen program-controlled switch now, but the manufacturing difficulties can only be solved by you." "And you have to complete the whole set.

The manufacturing technology must be completely transferred to Huawei, so that we can produce it ourselves!"

The 738 factory director promised that he would definitely do it.
