"Nowadays, a personal computer can cost up to 30,000 to 40,000 yuan, and the profit of one computer can reach 30,000 to 4,000 yuan. This will attract state-owned enterprises, private enterprises and foreign-funded enterprises to invest in the production of personal computers in China. By then, there will be dozens of companies on the market. Among domestic computer manufacturers, competition is fierce, and prices will drop to around 10,000 yuan, and the fittest will survive!”
"Domestic computer manufacturers cannot produce core computer hardware such as CPUs, motherboards, and hard disks. The operating system is also controlled by foreign companies. They still cannot get rid of the production model of helping foreign companies assemble dual-use machines. Jiangcheng Taobao Electric Co., Ltd. is in computer hardware. Our technical reserves are completely blank and we have no intention of helping foreign companies assemble dual-purpose machines.”
In front of the reborn, no matter how outstanding the computer and communication technology talents in the world are, they all look short-sighted.
Zhu Zhijie and everyone nodded repeatedly.
"Jiangcheng Taobao Electric Co., Ltd. did not enter the communications industry on a whim. There was no place to spend the money. If you don't want to do it, don't do it. If you want to do it, you must be the leader in the industry. Shanghai Shuguang Communication Technology Co., Ltd. not only develops and produces push-button telephones with independent intellectual property rights and pagers, and also develop and produce digital program-controlled switches with independent intellectual property rights. The purpose of developing and producing touch-tone telephones and pagers is to reserve technology and talents for the development and production of digital program-controlled switches and mobile phones with independent intellectual property rights. The company will purchase The most advanced telephone and pager production lines at home and abroad, the R&D personnel designed the three functions of dialing, talking, and ringing on one integrated circuit board, and then directly launched the production of touch-tone telephones."
The widespread use of mobile phones in his previous life eliminated landline telephones. Sun Jian also used cordless phones and handsets, using direct voice dialing, memory code keys, memory number chips, numeric keys, hands-free reception volume adjustment knobs... He will slowly move towards design. The staff imparts fashionable, practical and beautiful design concepts. If you do it yourself, the designed phone appearance will be refreshing and leading the trend in this period.
"Mr. Sun, the S1240 digital program-controlled switch produced by Shanghai Bell has been available for almost two years?"
Zhu Zhijie thought that the young Mr. Sun was too impulsive. He heard that the Ministry of Posts and Telecommunications spent hundreds of millions of yuan on introducing the S12 digital program-controlled switch technology and production line from the Belgian Bell Company. A modern production line costs tens of millions of dollars. Now only the state can Have the strength to invest in the production of digital program-controlled switches.
Others have become numb. Although they know the principles and brief history of communication, they are separated by lines and are not qualified to speak.
Telephone exchanges have developed from magnet telephone exchanges (manual exchanges), step automatic telephone exchanges, vertical and horizontal telephone exchanges, and air division program-controlled exchanges (analog exchanges) to today's time-division program-controlled exchanges (digital exchanges).
Digital program-controlled exchange, also known as stored program-controlled exchange, is an automatic telephone exchange controlled by an electronic computer according to a pre-programmed program.
Nowadays, air-division program-controlled switches are commonly used in China, also known as electromechanical and analog program-controlled switches. Air-division means that users have to occupy a pair of lines when making a call, that is, they have to occupy a spatial location until the call is completed.
The headquarters of Jiangcheng Taobao Electrical Appliances Company has an analog program-controlled switchboard that turns the switchboard into an extension. Only one outside line has been applied for at the Post and Telecommunications Bureau. Through manual transfer by the operator, each department can use this outside line at different times.
Time-division program-controlled switches, also known as program-controlled and digital program-controlled switches, transmit voice information in a certain time slot on a time-division multiplexing line to another time-division multiplexing line.
In 1970, France opened the world's first digital program-controlled switchboard, which used time-division multiplexing technology and large-scale integrated circuits. Subsequently, countries around the world vigorously developed it.
In the 1980s, digital program-controlled telephone exchanges became popular in Western countries.
Nowadays, digital program-controlled switches have just emerged in China. The domestic market share is occupied by Japan's NEC and Fujitsu, the United States' Lucent, Canada's Nortel, Sweden's Ericsson, Germany's Siemens, Belgium's BTM and France's Alcatel. There is a rumor in the industry that " "Seven countries and eight systems".
The Ministry of Posts and Telecommunications adheres to the principle that “technology must be the latest, production must be localized, and China must hold a controlling stake.”
In accordance with the principle, we sent inspection teams to the United States, Japan, the United Kingdom, France, Belgium and other countries to introduce advanced communication technology and seek companies with the intention to cooperate. Most of the cooperation negotiations were directly rejected by the other party, and the cooperation with the Belgian Bell Company (BTM) ) negotiations also moved from 1980 to 1983. The hard work paid off. In 1984, a Sino-foreign joint venture, Shanghai Bell Telephone Equipment Co., Ltd., was formally established, referred to as "Shanghai Bell".
Huhai Bell is the first Sino-foreign joint venture in the domestic high-tech field. At the beginning of its establishment, China Posts and Telecommunications Industry Corporation, which is affiliated with the Ministry of Posts and Telecommunications, accounted for 60% of the shares, Bell of Belgium accounted for 32%, and the Kingdom of Belgium cooperated Development Foundation accounted for 8%; in October 1985, Shanghai Bell's S1240 digital switch production line was announced to be put into production. This was also the first digital program-controlled switch production line in China.
"Are any of Mr. Zhu's colleagues experts in digital program-controlled switches?"
Sun Jian understood what Zhu Zhijie meant and did not overestimate his own abilities!
Sun Jian only knew a little bit about digital program-controlled switches. Before his rebirth, the Chinese people were angry because ZTE was suppressed by the United States for no reason. He finally realized the hypocrisy and rogueness of Western countries led by the United States. He had read a lot about "Great China" on the Internet. The article about the family history is deeply memorable.
The digital switches assembled from the materials provided by Shanghai Bell Company were not suitable for the domestic user environment and could not be sold. They suffered losses for three consecutive years and were on the verge of bankruptcy. In order to save this Sino-foreign joint venture, the Ministry of Posts and Telecommunications and the Shanghai Municipal Government enlisted the help of the Ministry of Finance to invest. Huge subsidies!
In its heyday, Shanghai Bell Company was the largest manufacturer of digital program-controlled switches in the world, occupying 80% of the domestic high-capacity digital program-controlled switches market and paying over one billion in taxes every year. However, even such a giant communications company was also replaced by Hou Weigui. ZTE led by ZTE and Huawei led by Ren Zhengfei were defeated!
Times create heroes, and heroes emerge from troubled times!
Of course, foreigners are happy to trade the market for technology. Although the state-owned enterprises control the shares, the core technology and R&D team are in their hands. Joint ventures generally do not have good results. Not only do they not get the core technology, they also lose the market. They either go bankrupt or fail. Eaten by someone else.
The domestic communications industry's pursuit of the world's advanced communications technology began with the development and production of digital program-controlled switches.
In 1985, Wu Jiangxinzheng, a young teacher at the University of Information Engineering, led a team to develop a computer system with a speed of 500 million operations per second. When the army was cut by millions, the project was also cut. Several years of hard work was locked in a cabinet, and everything came to an abrupt end. Stop, what will Teacher Wu, who comes from a general family and has no skills, continue to do? It has become an important issue of concern to the hospital leaders.
