Telecom broadband is the general term for China telecom operators to provide Internet access services for telecom users. It is presented to users with the unified business brand of "Tianyi Broadband", and provides users with seamless broadband access services through a unified Tianyi broadband client, integrating simple and practical applications such as unified address book, short message, Tianyi live broadcast, network disk, security expert, Tianyi video, 189 mailbox, etc., to meet users' high-speed Internet access, email sending and receiving, online stock trading, etc.

Access mode:

First of all, wired mode

1、ADSL

ADSL (Asymmetric Digital Subscriber Line Asymmetric Digital Subscriber Line Loop) is known as "the express train on the modern information superhighway". The commonly used downlink rate is as high as 8Mbps, and the uplink rate is as high as 640Kbps, which has the characteristics of fast speed, wide bandwidth, excellent performance and wide coverage.

2. Lan

Using Ethernet technology to provide users with FTTZ (fiber-to-cell)+LAN wired broadband access. Basically realize gigabit to community, 100 megabytes to residential buildings and 100 megabytes to users. Don't use a modem, it's highly reliable, and you can surf the Internet easily with only one Ethernet card.

3. Private Internet access

Internet private line access service refers to providing customers with a dedicated link for optical fiber access to the Internet, directly connecting to the broadband network of China Telecom, meeting the demand of10M to1000M, and realizing convenient and fast high-speed Internet access service.

4. Optical fiber access mode

Optical fiber access is an access network with optical fiber as the transmission medium. Technically, optical fiber access networks can be divided into two categories: active optical networks (AON) and passive optical networks (PON). Active optical networks can be divided into AON based on SDH and AON based on PDH. Passive optical networks can be divided into narrowband PON and broadband PON. FTTX access mode is mainly used for optical fiber. FTTX is not a specific access technology, but the promotion degree or use strategy of optical fiber in access network. Among them, according to the penetration degree of optical fiber to user groups, optical fiber access networks can be divided into FTTC (fiber to the roadside), FTTZ (fiber to the community), FTTB (fiber to the building), FTTO (fiber to the office) and FTTH (fiber to the home), which are collectively called FTTX.

Optical fiber access network, especially FTTH optical fiber access network, has the advantages of wide frequency band, large capacity, good signal quality and high reliability, and can provide a variety of services and even future broadband interactive services. It is the best solution to realize B-ISDN, so it is considered as the development direction of access network.

Second, wireless mode.

Wireless broadband is a wireless high-speed Internet service based on China Telecom's WIFI, Tianyi 3G and CDMA 1X networks. You can use the WiFi network card and 3G data card on your computer, use the unified wireless broadband client software, choose WiFi, Tianyi 3G and CDMA 1X networks to surf the Internet, and enjoy high-speed wireless Internet access services and rich network services.
