ADSL is the mainstream form of broadband Internet access. Next we will introduce some maintenance methods that often encounter faults when using ADSL for Internet access, hoping to help you.I. Why is the ADSL indicator normal? The most important indicator of ADSL is "ADSL. When there is no problem with the ADSL line, the light should be green.However, some users will also be disconnected when the "ADSL" indicator is normal, and restart the MODEM. This

Asyuncrical Digital Subscriber Loop Asymmetric Digital user line loop (ADSL) is a member of the XDSL family and is hailed as "express on modern information highway" by Western countries ". Because of its high downlink speed, high frequency bandwidth, and excellent performance, it is favored by many users and has become another new and faster and more efficient access method after modem and ISDN, it is also the most widely used access method in China.

Voice at command reference Note:Some modem do not have the voice communication function. The following table lists the voice AT commands that your modem can understand, including the Sound Amplifier command and the Tam command. Each Command description includes the command name, explanation, and related parameters. Remember:Your modem must be in Microsoft Windo

Hardware The connector is loose, the network cable is disconnected, the hub is damaged, and the computer system is faulty. For the above faults, you can observe the Modem, Hub, or computer indicators to help locate and replace suspected devices. Voltage is not normal, temperature is too high, lightning strikes-the voltage is not stable, it is best to configure the Modem with a small power UPS uninterruptibl
