ADSL掉线处理方法ADSL drop line processing methodADSL dropping involves many problems, including line fault (line interferenee), ADSL Modem fault (heating, quality and compatibility), network card fault (slow speed, old driver) and so on. Operators and users should do the following routine check: ADSL telephone line connector is safe and reliable: whether from the power line and high power electronic equipment; whether to install a telephone extension, fax machine, billing and other equipment between ADSL and home line separator: whether the correct installation of ISA card separator; out of the old-fashioned, replace the PCI card 10/1 OOM and the latest driver; ADSL Modem ADSL Modem heat is good; the indicator light is norma 1.The reasons for and reasons for ADSL dropping are as follows:First, the line problem(1) the quality of grounding wire.PC grounding performanee must be better・ Otherwise, static electricity will affect the transmission rate of ADSL and even will also affect the normal use of network equipment, and even the problem of disconnection, should be promptly rectification.cause the line to be dropped, resista nee shall be less tha n construetion of power supply some do not have ground wire,Generally, the PC ground10 ohms. In addition, due to the cloth is not standardized, and or ground quality substandard,(2) the line has strong interference source・Strong interference signal tower, electric welder, high-voltage power transformers and other trams or from the source to transmit user cable line in 100m radio, users receive offline clutter (copper clad steel wire shielding is weak・ The received signal ability), caused by strong interference on the subscriber line. The signal is often subject to interference from the offline part into the shield, because the trunk cable shielding layer, the interference effect is very small, if large parts of interfering with the use of some of the shielding line, it will reduce the rate due to interference caused by unstable or dropped・ In addition, the power line can not be parallel with the ADSL line, so as to prevent crosstalk, resulting in ADSL fault・(3) the quality of network card is unstable・The fault is that the network is disconnected as long as it is disconnected・ The users Modem DSL light is often bright, basically troubleshooting line failure, most of the problems are on the network card・ If you exclude the cable, computer, slot problems, the general quality of the network card is not stable, should promptly replace the network card.(4) subscriber line is far away.Irregular line dropping is caused by bad line quality or distanee. The ADSL tester can test signal attenuation and interference, and find better line replacement・ The subscriber line shall not exceed 5km, and the line from the junction box into the users room shall not exceed 100m・(5) access to the Internet, but the phone is disconnected・The reasons for the handover between the terminal board card off, because of the broken thread and the terminal board are very close, so the data induction can pass, and voice to go; if the user from the office is very near, indoor mixing line can also cause the fault line・(6) surfing the Internet and talking without taking care of each other.Generally bad outside line or bad contact・ When the user is surfing the net, the phone handle warning lamp is flashing, the WAN lamp is extinguished, and after the external line is repaired, the fault is immediately relieved.(7) can call, but the Internet dropped・In general, the connection of the user to the wrong line is to connect the Modem line to the phone, and then the phone can be used and the Internet is disconnected・ The ADSL Modem status light and the LINE light are not on. When checking the fault, you should check the wiring position of the equipment carefully, and change it as often as possible, so as not to connect the wrong line.(8) error line extension.Due to incorrect extension of the telephone extension, crosstalk results in data distortion on the internet・ If a telephone extension must be used, a separator shall be connected in series・Two, network card problemNetwork cards are gen erally PCI network card or onboard network card, select the time to choose a better quality, otherwise it may cause poor quality of the internet・ 10M or 10M/100M adaptive adapters are available・ In addition, many machines to share Internet access, using a dual card, which is the cause of conflict is also worthy of attention, then, should pull up connected to the LAN or other computer network card, only connect to the ADSL Internet card test, if the failure to resume normal, and then check the two network cards have no conflict・Three,ADSL, MODEM, or network card settingsNow, MODEM generally has 2 modes of work, one is the normal mode of using dial-up software, and the other is the automatic dial-up routing mode・ In normeil mode, you do not need to set up the MODEM, but you ca。
