Hangzhou Telecom Branch
is a branch of China Telecom Group Co., Ltd. in Hangzhou and a national telecommunications operating enterprise. Relying on scientific and technological progress, Hangzhou Telecom adheres to a high starting point, high speed, large investment, large output, and large-scale operations, and has gradually built a large-capacity digital program-controlled switching, satellite transmission, optical fiber communication , data communication and other communication means The modern communication network ranks among the best among provincial capital cities in the country in comprehensive communication capabilities, and the network scale, technical level and service methods have all reached a high level. In recent years, Hangzhou Telecom Branch has actively responded to the municipal party committee and government’s comprehensive implementation of the “No. 1 Project” and strived to build Hangzhou into the “Paradise Silicon Valley” to further accelerate the development of broadband services. In 1998, the construction and application of urban broadband networks began. At present, it has two broadband network platforms, ATM and IP, realizing fiber optic to urban buildings, communities and villages. The city has built a full-coverage optical fiber metro network, which is distributed in almost every road and building in Hangzhou, with a total length of more than 1,300 kilometers. Through the inspection and research of residential areas and commercial and residential buildings in Hangzhou, Hangzhou Telecom Company used today's most advanced broadband access technology and means to propose solutions suitable for a variety of properties and residential areas, and focused on cost investment. , Provide communication support and good services to fully meet diverse individual needs. At present, broadband access methods tailored for hotels, business buildings, high-end residential areas and ordinary families using optical fiber access, Category 5 line access, ADSL, FTTX + LAN and other technologies are fully rolled out in Hangzhou. At the same time, the city's Internet export relay system and access system have been comprehensively expanded and optimized. At present, the backbone layer of Hangzhou's broadband IP network has been built, and the switching capacity of the core network routers has reached 80G. The typical access methods provided by Hangzhou Telecom Broadband Network are: FTTx+ADSL and FTTx+LAN mode. FTTx + ADSL mode (asymmetric digital subscriber loop) uses existing telephone lines to provide high-speed Internet access technology, making full use of the cable resources of the existing fixed telephone network, without affecting normal telephone communications, through a telephone Line, realizing the transmission method of telephone communication and data communication without interfering with each other at the same time. ADSL technology has high transmission rate and wide frequency, and can support multiple access application modes. It provides asymmetric transmission bandwidth for uplink and downlink. The uplink rate can reach up to 8Mbps and the uplink speed can reach IMbps. It adopts point-to-point topology . Users can Exclusively high bandwidth and speed, with good security. The smart community uses the 100M Ethernet port of the DSLAM equipment of the ADSL broadband system to form an overall local area network between the home ADSL terminal and the property management platform to provide support for property management to carry out various online value-added services. FTTx+LAN mode uses IP technology to build a broadband network and provides access technology for high-speed Internet access. FTTx+LAN is suitable for residential areas and office buildings where integrated wiring systems have been laid. Realize broadband access with 1000M bandwidth to the community, 100M bandwidth to the corridor, and 10M bandwidth to the desktop. There are also fiber-to-the-office, fiber-to-the-home, fiber-to-the-desktop and other access methods to meet the needs of different users. FTTx+LAN technology adopts star topology structure, and users share bandwidth. The smart community uses the 100M Ethernet port of the core equipment of the broadband system to form an overall local area network between home terminals and the property management platform, providing support for property management to carry out various online value-added services.
