Telecom Broadband is a comprehensive term used by Chinese telecom operators to provide internet access services to their users. It offers a unified brand called "Tianyi Broadband" through a centralized client application, delivering seamless broadband connectivity. Alongside high-speed internet access, it integrates various useful features such as an address book, SMS, Tianyi Live, online storage, security tools, video services, and 189 email, catering to a wide range of needs like online shopping, stock trading, streaming, gaming, remote learning, telemedicine, and more.
**Access Methods**
**Wired Mode**
1. **ADSL (Asymmetric Digital Subscriber Line)**
ADSL is often referred to as the "express train on the modern information highway." It typically offers a downstream speed of up to 8 Mbps and an upstream speed of up to 640 Kbps. Known for its fast speed, wide bandwidth, and broad coverage, it's a reliable option for many users.
2. **LAN (Local Area Network)**
This method uses Ethernet technology to deliver broadband via FTTZ (Fiber to the Zone) + LAN cables directly to homes. It provides speeds of up to 1 Gbps in the community, 100 Mbps in buildings, and 10 Mbps at the user level. No modem is required, making it highly stable and easy to use with just an Ethernet card.
3. **Internet Line**
An Internet private line service connects customers directly to China Telecom’s broadband network using fiber optics. It supports speeds ranging from 10 to 1000 Mbps, offering fast and convenient high-speed internet access.
4. **Fiber Access**
Fiber access involves using optical fibers as the transmission medium in the access network. It can be divided into Active Optical Networks (AON) and Passive Optical Networks (PON). FTTX (Fiber to the x) is a general term referring to how far fiber reaches into the user’s premises, including FTTC, FTTZ, FTTH, and others. Fiber access networks, especially FTTH, offer high bandwidth, excellent signal quality, and support for future interactive services, making them the ideal solution for next-generation broadband.
**Wireless Mode**
Wireless broadband services are available through China Telecom's Wi-Fi, Tianyi 3G, and CDMA1X networks. Users can connect via Wi-Fi cards or 3G data cards using the unified wireless broadband client software. This allows for high-speed wireless internet access and a variety of online services.
**How to Enable IPv6 on China Telecom Broadband**
To enable IPv6, follow these steps:
1. Press **Win + X** and select **Command Prompt (Admin)**.
2. Type the following commands one by one:
```
netsh
interface ipv6
isatap set router 202.112.26.246
```
A confirmation message will appear once the command is successfully executed.
**Alternative IPv6 Configuration Steps**
For Windows 7 users, you may need to run the following commands:
```
netsh int ipv6 install
netsh interface ipv6 isatap set router isatap.sjtu.edu.cn
```
You can also use other university-provided IPv6 relay servers, such as:
- **Huazhong University**: isatap.hust.edu.cn (218.199.111.9)
- **Tsinghua University**: isatap.tsinghua.edu.cn (59.66.4.50)
- **Shanghai Jiao Tong University**: isatap.sjtu.edu.cn (202.120.58.150)
- **Beijing University of Posts and Telecommunications**: isatap.bupt.edu.cn (211.68.71.43)
After configuration, test your IPv6 connection by visiting sites like:
- [http://ipv6.tsinghua.edu.cn](http://ipv6.tsinghua.edu.cn)
- [http://bt.byr.cn](http://bt.byr.cn)
If you still face issues, consider using tools like Veno or other proxy plugins. Some users have reported faster download speeds with 8M broadband, reaching up to 600KB/s.
This guide should help you get started with IPv6 on your China Telecom broadband connection. If you encounter any problems, feel free to ask for further assistance!
