Most telephone lines in your home will be analog lines which are safe for amplified phones and ring signalers. However, if you are using an ISDN line for your internet connection, do not use any assistive device on this line. ISDN is a digital technology and may damage your assistive equipment. If you have DSL service for your internet connection, this is analog technology and is safe for use with assistive equipment.

When considering an ISDN or DSL line, know the pros and cons. Cost: ISDN through the telephone company costs an average of $60 / mo., plus a connection fee, and DSL is usually about $45 / mo. Sometimes connection fees are discounted when signing a one year term agreement (check with your provider). With ISDN, you should get 2 to 3 times faster downloads, and DSL is generally 10 - 20 times faster than dial up.

option is now available in the order process to migrate your ISDN line to a normal phone line, if your line is DSL suitable. Something to consider is that your ISDN line will normally have two phone numbers and two lines attached to it. When downgraded, the second line and number will be lost ? make sure you check this out fully before ordering as it cannot be readily reversed. As there is an extra step or two involved, ISDN line to DSL orders may take slightly longer.

If you qualify for DSL, we can provision it through your existing phone line. No additional telephone line is needed.

To find out now, please enter your phone number on the "Order DSL Now page" or in any of the boxes throughout the site that say "Search for Special Offers." This process allows us to tell you if your line can be used for high speed internet.

The system should not influence a DSL or ISDN at all. Because the internet traffic is on a different frequency, it is not perceived by the phone as being a phone call.

That all depends upon the telephone companies offering both services. The two services are not the same -- ISDN provides two voice channels or a 128 Kbps data channel while DSL is predominantly a data pipe providing an asymmetrical bandwidth of up to 8 Mbps downstream and 1 Mbps upstream under good conditions. However, an DSL access network will be an overlay network and therefore will not require the expensive and time-consuming switch upgrades that held ISDN back for so long.

Yes! DSL will either provide DSL service on your existing phone line or bring a new data line into your home for your DSL, depending on where you live. In either case, you will be able to use your existing home telephone line for phone calls while you're surfing the web.

People with a mild hearing loss can benefit from phones and in-line amplifiers with a gain of 24 to 30 decibels. All of the phones we offer are suitable for a mild hearing loss. Individuals with mild to moderate hearing loss will want a phone with a gain of 30 to 40 dBs. Also, since this type of hearing loss often involves an amount of distortion that makes voices difficult to understand no matter how loud they are. A phone with tone control is recommended to address this problem.

DSL is Faster: ISDN provides two voice/data channels, each at speeds of 64 Kbps, while DSL is predominantly a data service providing up to 1.5 Mbps downstream and up to 512 kbps upstream. Business DSL offers T1-like speeds of up to 1.5 Mbps-more than 10 times faster than ISDN! DSL is "always on": ISDN is a dial-up service (like a regular telephone line) that's digital and carries both data and voice; Business DSL is "always connected"

No. DSL and Wireless services give you greater "bang for the buck", and come in speeds up to 3.0M, but you may not be able to get DSL or Wireless at your location. We recommend ISDN for locations where DSL and Wireless are not available and T-1 is not needed or affordable.

DSL is even faster than ISDN. And DSL sends data and voice over the same line so you talk on the phone while you connect to the Internet.

Your ISDN line will not support both DSL and ISDN; this means that you must have one set of wires for each service. If you want to drop ISDN service in favour of DSL you can use the wires that were installed for the ISDN line. DSL needs a few important hardware items for it to correctly work. In order to separate your voice transmissions from data over the copper line you will need to install a simple and small splitter (available from us for $ 95.00).

A modem converts your computers data packets into an analogue signal (sounds a bit like a fax machine) and uses the normal telephone network to pass this to your ISP (Internet Service Provider) who then turns the signal back into data and thus enabling your computer to communicate on the Internet. ISDN also uses the telephone network to transmit data to the ISP but does not convert the data to analogue signals; instead it uses digital equipment at the exchange and on your computer.

DSL will be the cause of ISDN's demise for several reasons: - ISDN is only available in two speeds: 64 Kbps and 128 Kbps, both of which are significantly slower than most DSL connections. - ISDN sometimes offers dedicated, always on access but not always. Furthermore, ISDN is subject to additional per-minutes fees in many locations. ISDN fees can easily be in the hundreds of dollars on a monthly basis. -ISP's will charge between $30-150 a month to provide Internet access to ISDN customers.

You can have either a dedicated analogue line or ISDN or ADSL as required there are small monthly charges for extra lines.

Sure. Just get the appropriate adapter or cable to plug into the 1/4" TRS jacks and use the input like any other line input.
