What are the types of xDSL network access methods?

In China, the mainstream broadband access modes are as follows: ADSL, VDSL, FTTB+LAN dynamic IP+Web authentication, FTTB+LAN static IP+Web authentication, wired broadband Internet access, etc. Many access schemes use routers, but compared with different access methods, the setting methods of the routers are not the same, today we will take the broadband road with more compatibility TP-Link as an example, and talk in detail about the specific methods of router settings under different broadband mode access.

1. ADSL: ADSL access is divided into ADSL modem and ADSL router, if it is ADSL

Router, you need to change its Internet mode to RFC 1483 first

bridge, and then connect to the TP-Link router. Then log in to the web management interface of the TP-Link router, select the ADSL virtual gift dialing method through the "Setup Wizard", and use the "Internet ID" and "Internet Password" provided by the service provider

Once you've filled in the appropriate fields, click Next.

2. VDSL: The access setting is the same as ADSL. However, in some places, you will encounter that you can get on QQ, but you can't open the web page, then you need to log in to the TP-Link router, and change the value of MTU to 1492 under the WAN port setting in the network parameters.

3. FTTB+LAN dynamic IP+Web authentication: log in to the web management interface of the TP-Link router, select "Ethernet broadband, automatically obtain IP address (dynamic IP) from the network service provider (for example: China Telecom)" through the "Setup Wizard", after the setting is completed, go to the running state to see if the WAN port obtains the IP address, if you get it, and then enter any ** in the IE address bar, the authentication dialog box will pop up. Fill in the username and password provided by the network service provider.

4. FTTB+LAN static IP+Web authentication: Log in to the web management interface of the TP-Link router, select "Ethernet broadband, network service provider (for example: China Telecom) provides a fixed IP address (static IP)" through the "Setup Wizard", after the setting is completed, and then enter any ** in the IE address bar, the authentication dialog box will pop up, and fill in the username and password provided by the network service provider.

5. Wired broadband Internet access: Log in to the web management interface of the TP-Link router, select "Ethernet broadband, automatically obtain the IP address (dynamic IP) from the network service provider (e.g., China Telecom)" through the "Setup Wizard", and restart the cable after the setting is completed

modem will do the trick.

XDSL includes ADSL and VDSL. All virtual broadband through ** lines is called XDSL.

XDSL technology is to use digital technology to transform the existing analog user line. Leave the 0 4kHz low-end frequency for **, and use the rest for Internet use. The type is divided into, adsl, hdsl, sdsl, vdsl, dsl, the specific difference is the transmission range, bandwidth and other differences, just search for the information.

DSL mainly includes HDSL, SDSL, VDSL, ADSL, and of course, others. It's just not common.

What you should ask is that there are several modes of broadband, broadband is divided into ADSL and optical fiber, ADSL is connected to the cat through the ** wire, and it is connected to your computer.

In the access network, there are 9 main access modes to choose from: PSTN, ISDN, DDN, LAN, ADSL, VDSL, CABLE-MODEM, PON and LMDS, each of which has its own advantages and disadvantages

PSTN dialing: The most widely used.

The mode is narrowband access, which is a one-line connection.

The way is broadband access, which is often referred to as super one-line communication.

Mode: Private line access mode, optical fiber access, generally used by Internet cafes or enterprises.

4.The modem method is now basically obsolete.

5.The cell LAN access mode generally shares a bandwidth of 10 Mbit/s, and is generally not opened for individuals.

Power line access is a relatively advanced one.

7.Cable modem access speed is more than 10m, and bandwidth is shared.

8.Satellite access.

Let's start with that, there are quite a few, but those individuals don't need it.

There is a ** cable connection to the Internet.

There's also broadband Internet access (dial-up internet) and the fastest light internet.

Comparison table of Internet access methods.

Access mode Optional scheme Features Applicable object Access mode Required hardware.

Dial-up access Ordinary modem is simple to install Home access **line, **can not enter modem, network card, **line.

ISDN dialing is very fast and the family can access the Internet at the same time to play ** modem, splitter, ** line.

ADSL virtual dialing speed fast home, public place modem, shunt, ** line.

Leased line access cable modem broadband high ** transaction access to high-speed cable modem high-speed cable modem.

DDN Leased Line Banking, **, Meteorological Access to High-Speed Cable Modem High-Speed Cable Modem.

Fiber optic access Unobstructed Office Visitors Access to high-speed cable modems High-speed cable modems.

Wireless access GPRS quick login, high-speed transmission Office Visitors Insert unlimited Internet card Computer, wireless network card.

Bluetooth technology saves costs for those who go out to work Insert unlimited network cards for computers and wireless network cards.

LAN access.

I'm sorry, I'm not very clear about this question, so I don't know either, I hope you can get a satisfactory answer, I wish you all the best, bye.

The bandwidth is up to 8 Mbit/s uplink and 512 KB downlink. It needs to be dialed with a cat, which is suitable for mass users.

2.Leased line: Optical fiber or ** line leased line, fixed public IP address. It is generally used by Internet cafes or enterprises.

3.Community broadband, directly connected to the cell switch, provides 100 Gigabit network interface.

Yuerff - Assistant II level.

It should be "ADSL bandwidth is up to 8M downlink and 512K uplink".

1. Ordinary dial-up access, convenient, as long as you can call ** line and a modem, no need to apply, ** is an hour in our side, the speed is poor, suitable for temporary Internet access, sending and receiving point mail.

2. ADSL dial-up access, you need to apply for it, you need a ** and ADSL modem, generally monthly or annual service, ranging from 500 to more than 1,000 per year. The speed is fast, suitable for people who have been surfing the Internet in a fixed place for a long time, service providers such as telecommunications, Netcom, etc.

3. Community broadband access, there are many service providers, first the optical fiber access to the community, the access fee seems to be 2000 yuan per month, note that there is a difference between this trillion and ADSL one megabyte. Then distributed to each household, the more people who use the speed quickly, the cheaper it is, of course, the more the speed is apportioned, and the relative speed will come down.

4. Wireless Internet access, suitable for laptops, with wireless network use, you need to buy Unicom's CDMA or mobile GPRS card, which is slow and expensive. You can only browse simple messages and send and receive some emails.
