Pioneered by the early nineties, and reached the international advanced level of SDH-drop multiplex equipment, lines have been installed in the project and open, is organizing the mass production. cheap nfl jerseys Along the device so that the local telephone, can be very flexible and easy to access long-distance lines, which greatly improved the operational efficiency and cost-effective telecommunications network.
11, Intelligent Network Systems
Intelligent Network system to practical use. Intelligent network platform has been put into operation in the bureau. With it, individuals can use the account password on any phone with a phone on their own, like access to both domestic and international services to a variety of telecommunications services.
12, ISDN switches
To integrate multiple communication services (ISDN) switch has been practical, and is used in military communication networks. Dawn machines and 04 machine-based, intelligent network switching functions (SSP) will soon practical.
13, China Digital Cordless Phone
Mobile phones with honeycomb (cellular phone) the main function of the cost for one-third of China's digital cordless phone (CDCT) mlb jerseys made significant progress in the system, has been able to network shows.
14, Code Division Multiple Access Communication
Greater capacity, lower cost next generation mobile communication system 11 Code Division Multiple Access (CDMA) key technology breakthrough. Communications department has decided on this basis, the development of Chinese products.
15, ATM switching equipment
Next-generation switching technology, asynchronous transfer mode (ATM) equipment, has made breakthroughs in key technologies, including inter-port cross-connect device results 16xl6 has been put into operation in Tianjin Tanggu bureau, it can be more than 30,000 telephone lines as needed to deploy Coach handbags . 96 years is expected to complete 10 million yuan in sales.
16, aerial remote sensing real-time transmission system
China's vast territory, disaster-prone, especially unexpected natural disasters each year to the national economy and people's lives and property caused serious losses. In order to keep abreast of the situation and decision-making for the disaster assessment and disaster relief services, 863 plans and the national "Eighth Five" science and technology research program jointly supported by the airborne remote sensing system for real-time transmission. sports jerseysThe system can penetrate clouds and rain and fog in the microwave remote sensing technology and advanced communication technology, satellite remote sensing images of a ground plane of a real-time transmission and ground image processing. In 1995, the Poyang Lake area and flooding in Dongting Lake area, remote sensing aircraft flew to the disaster areas, real-time remote sensing images will be transmitted to Ministry of Water clear the ground control center, hit land and sea boundaries clear, clear flooded areas, through existing geographic information system quickly made the assessment of flood losses in the flood relief work played a role.
