Wang Xienian and Zhu Zhijie, along with Ye Mingxin and Ye Mingde, invited two academic members and three expert professors from Jiaotong University. There were a total of 17 members of the expert appraisal committee. On December 21 last year, they conducted an inspection at the Shanghai Shuguang Communication Technology Research Institute building. Participated in the SG-1000 digital program-controlled switch development achievement appraisal meeting.
The SG-1000 digital program-controlled switch project has two digital program-controlled switch models: SG-1000 and SG-500, and five analog program-controlled switch models: SG-200, SG-100, SG-50, SG-20 and SG-10. It can meet the telephone communication needs of county telecommunications bureaus, large industrial and mining enterprises, star hotels and units and schools.
Digital program-controlled exchange is an automatic telephone exchange controlled by a computer according to a pre-programmed program. Its full name is stored program-controlled telephone exchange. It requires a microcomputer to manage the program-controlled exchange. Analog program-controlled exchange does not require microcomputer management and requires manual access.
Digital program-controlled switches are composed of hardware and software appraisal committees. The hardware includes the voice channel part, the control part and the input and output parts, and the software includes the program part and the data part. For domestic research institutions, the software part is more difficult.
The software part is the strength of Jiangcheng Kunpeng Software Company, which has completely independent intellectual property rights.
While discussing their comments, members of the expert appraisal committee walked to the venue from time to time and used twenty Shuguang brand telephones connected to the SG-1000 appraisal switch to make calls to feel the voice quality, connection speed, etc. of the switch. The test appraisal committee also added from time to time. Measure some data to answer the delegates’ questions.
The members of the expert appraisal committee asked in detail, and the appraisal meeting lasted for more than three hours. The SG-1000 digital program-controlled switch project successfully passed the appraisal of the expert appraisal committee.
my country's telephone exchange manufacturing industry started relatively late. It was not until 1957 that the first automatic stepping telephone exchange factory was established, and it was not until 1958 that an analog switch was successfully developed.
In the 1970s, after the birth of foreign program-controlled switches, the government listed the research and development of program-controlled switches as one of the 108 key science and technology development projects in the "National Science and Technology Development Outline 1978-1985". This plan was led by the state and assigned research tasks to various scientific research institutes. No breakthroughs were achieved in the 1980s.
Planning and research failed the first time.
In 1982, the Fujian Provincial Post and Telecommunications Administration spent a huge sum of US$6 million to introduce F1.5 million digital program-controlled switches from Japan's Fujitsu, installed them in Rongcheng and Xincheng, and successfully put them into commercial use.
With Fujian Province taking the lead, Secretary Ren of Guangdong Province has also made the decision. Yangcheng should also install it, and if it wants to install it, it will install 26,000 gates!
Provinces and cities rushed to spend huge amounts of foreign exchange to import digital program-controlled switches.
At that time, the first-line cost of imported digital program-controlled switches was US$1,000.
In 1983, the Minister of Culture and Culture of the Ministry of Posts and Telecommunications saw that the situation was not right, and immediately organized the Posts and Telecommunications Corporation to negotiate with BTM to introduce the S1240 program-controlled switch production line and technology and establish Shanghai Haibell Co., Ltd.
Since then, 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 have established joint ventures with domestic enterprises to enter the domestic market. The country has determined " The general direction of introducing, digesting, and absorbing foreign advanced technology and promoting the independent research and development and production of program-controlled switches by domestic enterprises.
The domestic digital program-controlled switchboard market is monopolized by products in eight formats from seven countries. From rural telephone to the national backbone telephone network, no one is spared.
The monopoly has made digital program-controlled switches very expensive, which directly affects the price of installing telephones. To install a telephone at home, you need to pay an initial installation fee of about 5,000 yuan.
The country hopes to exchange technology for markets and encourage domestic research institutes and enterprises to develop digital program-controlled switches.
In 1986, the Institute of Posts and Telecommunications of the Ministry of Posts and Telecommunications successfully developed a 2,000-door digital program-controlled switch DS-2000, but it has not yet entered commercial operation.
Vice Minister Song of the Ministry of Posts and Telecommunications said on the spot that the SG-1000 digital program-controlled switch, which has completely independent intellectual property rights, passed the appraisal of the expert appraisal committee. It was a major breakthrough in the field of domestic digital program-controlled switches and brought glory to the country. He praised the hard work of the project appraisal committee and encouraged Ye Mingxin's team continues to develop Wanmen digital switches with independent intellectual property rights; and hopes that Shanghai Shuguang Communication Technology Company will produce the successfully developed SG-1000 as soon as possible and put it into commercial operation.
Once the SG-1000 successfully developed by Shanghai Shuguang Communication Technology Co., Ltd. enters commercial use, it will be the first domestic company to independently produce digital program-controlled switches, breaking the technology and price monopoly of Western companies (including joint ventures), and exerting a great influence on the domestic post and telecommunications industry. The development is of extraordinary significance!
The Ministry of Posts and Telecommunications stands at the height of national interests, is happy to see the results, and actively encourages!
Obtaining the appraisal certificate from the National Expert Appraisal Committee is equivalent to obtaining the network access license from the Ministry of Posts and Telecommunications. The SG-1000 digital program-controlled switch will apply for the company's invention patent.
Director Yang of the Shanghai Science and Technology Commission responded to the application report submitted by Li Tao for Shanghai Shuguang Communication Technology Co., Ltd. to be a high-tech enterprise. He responded on the spot and immediately after returning home, the appraisal committee organized an expert review.
Deputy Mayor Huang, who is in charge of industrial production, invited Shanghai Shuguang Communication Technology Company to enter the Caohejing High-tech Development Zone on behalf of the Shanghai and Shanghai government. Li Tao expressed his willingness to join on the spot.
The next morning, Li Tao sent the 150,000 yuan awarded by the Shanghai Shuguang Communication Technology Company's Project Appraisal Committee to Ye Mingxin, who distributed it to the members of the project appraisal committee.
How to distribute is a matter for Ye Mingxin, the general director of the project appraisal committee, and Zhu Zhijie, the deputy general director?
After Li Tao came back, he told Mr. Sun that the members of the project appraisal committee were very motivated.
Passing the appraisal by the National Expert Appraisal Committee only shows that the SG-1000 digital program-controlled switch has met the basic requirements for the design indicators of digital program-controlled switches and can be used in actual communication networks. This is not the end yet!
After the SG-1000 appraisal, Wang Xienian sent people and vehicles to transport the equipment to Shanghai County. Ye Ming's new project appraisal committee opened a test bureau at the county post and telecommunications bureau, connected to the network for operation, and will conduct a two-month practical test. Problems are discovered and improvements are made in a timely manner.
The results will be available after the Spring Festival!
Li Tao received instructions from Mr. Sun and took the promise of Shanghai Shuguang Communication Technology Company to invest five million yuan to build supporting facilities such as Shanghai Shuguang Communication Technology Research Institute, Shanghai Shuguang Communication Technology Company complex building, production workshops and employee dormitories. After reading the book and report, Wang Xienian and Wang Xienian directly found Deputy Mayor Huang who was in charge of Shanghai Industrial Production.
Vice Mayor Huang immediately gave instructions to allocate 50 acres of land in Area D of Caohejing High-tech Development Zone to Shanghai Shuguang Communication Technology Company for a fee, without paying land development fees, and promised to wait until the high-tech enterprise certification approved by the Science and Technology Bureau is issued. After graduation, you will be exempted from paying corporate income tax for three years.
The new factory area of Shanghai Shuguang Communication Technology Co., Ltd. took about one year from design to completion.
Sun Jian had no intention to put the SG-1000 production line in Shanghai from the beginning.
