Also known as Broadband, an ADSL (Asymmetric Digital Subscriber Loop) line is a form of Digital Subscriber Line in which the bandwidth available for downstream connection is significantly larger than for upstream. Although designed to minimise the effect of crosstalk between the upstream and downstream channels this setup is well suited for web browsing and client-server applications as well as for some emerging applications such as video on demand.

Each home and each outlet has slightly different power line impedance and power line noise. Each amplifier is affected by power line impedance and power line noise differently. Power line conditioners try to reduce this line noise. Some also change the power line impedance in a way which is supposed to be better. We will leave it to your ears to decide if these devices help the sound of your system enough to justify their expense. See similar questions...

ADSL filters are small adaptors for domestic phone sockets, necessary to prevent interference between voice and Internet calls on a broadband line. One filter is needed for each wall socket used by a telephone or piece of telephone equipment attached to the broadband line (eg. phone, fax, games console). Routers purchased from our partner supplier DSL Shop come with two filters included. Additional filters, if required, can also be purchased from DSL Shop. See similar questions...

We will only be able to provide ADSL on a Copper wire telephone line. The line between the premises where the ADSL is to be installed, and your local BT exchange should not contain any Fibre Optics, Aluminium, or other line types. Additionally, the following products are incompatible with ADSL Services, and will need to be removed prior to installation: If your current line is an ISDN line, we can remove and convert it to ADSL in one procedure.

Yes. ADSL services can currently only be provided over standard Telefoñica analog exchange lines where the exchange has been ADSL enabled, you are not too far from the exchange and the line is of sufficient quality to support ADSL broadband See similar questions...

ADSL uses a far higher frequency to transfer data across your phone line than a typical voice call, which means it offers little interference. This means that you can be using your phone line at the same time that you are connected to ADSL. All you need to do to adjust the way you currently use your phone line is to plug in an ADSL line filter for every device that uses the line. This stops the phone and other devices such as a fax machine from interfering with your Internet connection. See similar questions...

Most service providers offer an up to 2Mbps or up to 8Mbps (Mbps = Mega bits per second), when you buy one of these services you will receive the connection speed that your specific line is able to support. Some providers do allow you to choose specific speeds at order time, e.g. 250Kbps (Kilo bits per second), 500Kbps, 1Mbps and 2Mbps, in this cases what service to order will vary according to your needs.

No. ADSL can run on your existing basic phone line. If you do not have a TTCL connection then you need to get one from TTCL before you can ask for an ADSL broadband connection. See similar questions...

No – ADSL is designed to favour downloading rather than uploading. As a Web server's prime objective is to upload data as fast as possible, ADSL is not the best choice. Also, as ADSL is a variable bit-rate system, the available bandwidth for uploading may change, slowing the server performance. See similar questions...

Standard ADSL requires a POTS (Plain Old Telephone Service) line, which is what most homes and small businesses have. Generally it must be a BellSouth or a BellSouth resale line. Also, you must be within 18 thousand feet, or closer for higher speeds, of a BellSouth Central Office or Remote DSLAM. Send us your phone number(s) and address and we will check it to see if you qualify. Custom ADSL uses a phone line which we supply. Send us your address and we will check it to see if you qualify.

Yes! ADSL modems use digital coding techniques to squeeze up to 99% or more capacity out of a phone line without interfering with your regular phone services. That means you could be simultaneously talking on the phone or sending a fax - while surfing the World Wide Web. The two services (voice and data) operate independently of each other even though they are using the same telephone line. See similar questions...

ADSL provides simultaneous Internet and voice/fax capabilities over a single telephone line. It also provides high-speed Internet access with "instant on" capability. ADSL is a cost-effective solution for businesses and it is a more secure method of transferring data than technologies such as cable modems. See similar questions...

Connect your ADSL modem to the phone socket using the supplied micro-filters or through the fitted master socket. Once you boot your computer up you should see two lights on the modem both of these will flash in a sequence. After thirty seconds to a minute these should both turn solid green. If both lights are solid green then your line is set-up to use your ADSL connection, ie. your line is activated. See similar questions...

ADSL broadband connection takes your existing telephone line and adds a dedicated computer link between the telephone exchange and your home. The connection uses a transmission coding protocol called Discrete Multi Tone (DMT), which operates at a frequency above that of normal voice, fax, or data transfer. See similar questions...

ADSL is not currently available for aerial phone lines. The current ADSL product launched in October 2000 has proven to be a technical challenge for aerial phone lines: Dies führte dazu, dass ADSL auf Freitleitungen seitens Swisscom unterbunden werden musste. Daraus entstand in der Vergangenheit einige Verwirrung und kontroverse Aussagen. See similar questions...

Yes. BT's telephone billing (line rental and call charges) are unrelated to your ADSL. You will however not have to make any calls to the Internet, as the ADSL is an always-on connection. See similar questions...
