Ultimate Tutorial: FAQs about ADSL hardware

Ultimate Tutorial: a collection of FAQs about Frequently Asked Questions about ADSL hardware. The FAQs about ADSL hardware are mainly answered by common questions raised on the Internet. You can find answers to all kinds of questions, so you can easily solve the problem without any difficulty. Hurry into the world of ADSL Common Hardware problems.

ADSL Common Hardware problems: Why is PPPoE unavailable on computers on the LAN when the ADSL connection uses 10 M/100HUB?

Answer: The 10 BASE-T standard (10 M) is used for ADSL. It can connect to a 10/100 m hub, however, if the connection speed between your computer and the HUB is 100 MB, The HUB's 10/100 switching module does not currently support PPPoE well.

Therefore, PPPoE may not be able to locate the ADSL signal at a speed of M, so it cannot be used. The solution is to create a 10 m network cable using a 10 m wiring method for the PPPoE dial-up computer, or use the NIC setup program to forcibly set the speed of the network card to work at 10 m.

ADSL Common Hardware problems: Why is my ADSL data traffic too high?

A: We generally think that this is a poor quality or compatibility of NICs, especially for 10 m NICs of the old ISA bus. Because PPPoE is a relatively new technology, such NICs may have compatibility problems and are slow, cause the final line of the conflict to be deadlocked or even crashed.

ADSL Common Hardware problems: is the speed of using 0 M/M Nic on ADSL different?

A: In general, the speed will not be different, because the ADSL Internet access speed is not limited by the NIC and less than 10 M, but for the 10 M Nic, A large part of the ISA interface uses the I/O addressing mode, and its CPU usage is extremely low in efficiency, which will slightly affect the speed, therefore, we recommend that you use the PCI interface 10 M/M dual-speed adaptive Nic.

ADSL Common Hardware problems: I am using a remote IDC from the telecom branch of the Telecommunications Bureau. Can I install ADSL?

A: currently, the distance between ADSL technology and the Telecommunications Bureau is less than 5 kilometers. Therefore, it depends on the situation. Because ADSL has high requirements on the line, therefore, to ensure the quality of communication, it is generally considered that less than 3KM is better.

ADSL Common Hardware problems: Will ADSL be dropped like a common 56 K Modem?

A: When any connected device fails, ADSL will also be dropped. However, as long as the line quality is good, the chance of disconnection is still very small.

ADSL Common Hardware problems: ADSL does not mean to use the ADSL line. Why didn't I see the Telecommunications Bureau change the line after I installed it?

A: In fact, the physical media used by ISDN lines, telephone lines, and ADSL lines are common telephone lines, but the signal standards are different. The communication board will not change the lines for you, you can only connect your telephone lines to different devices in the IDC of the Telecommunications Bureau, which is invisible to end users.

FAQs about ADSL hardware: Will I generate a telephone fee like ISDN or 56 K modem if I use ADSL to access the Internet?

A: No. The channels used by ADSL for data communication do not enter the local switch, and no telephone fee is generated. Of course, you still need to generate a call charge when calling through the ADSL line.

ADSL Common Hardware problems: Why does my ADSL often get disconnected?

A: This involves many problems, including ISP access server faults, line faults, line interference, adsl modem fault fever, quality, and compatibility), slow Nic speed, and outdated drivers) among them, we recommend that you perform the following checks as far as possible.

The ADSL telephone line connection is secure and far from power cables and high-power electronic devices. No telephone extension or fax machine can be installed between the ADSL entry line and the separator. The splitter is correctly installed to eliminate old ISA NICs, change to a 10 M/m pci Nic and the latest driver to ensure sound heat dissipation of the adsl modem. Finally, contact your ISP.

ADSL FAQs: Can I connect to the ADSL device on the extension?

A: currently, no. You can only connect to the ADSL terminal device on a linear phone. ADSL is a Transmission Technology Based on twisted pair wires. Twisted Pair wires wrap two insulated copper wires together with each other according to certain rules, which can effectively resist external electromagnetic interference.

However, most of the telephone lines on the market are parallel lines. Many of the lines from the telephone company's junction box to the user's telephone are parallel lines, which is very unfavorable for ADSL transmission, too long non-twisted pair wires may cause unstable connection, DSL light flashing, and other phenomena, thus affecting Internet access.

Because ADSL overlays high-frequency digital signals on the low-frequency voice of common telephone lines, the addition of any device in the connection from the telephone company to the ADSL filter will endanger the normal transmission of data, therefore, do not connect devices such as telephones and telemarketers before filters.
