How DSL works...
DSL circuitry is not as easy to make work as people have been lead to believe. DSL circuits are distance sensitive. The longer the loop of wire from your home or business back to the phone company the greater the loss of speed. The maximum of any DSL circuit is roughly 20,000 feet.
Your phone service works on a different principle. While loops can be longer on voice phones there are ususally amplifiers in the loop so your wires can be longer and you’ll still be able to hear. That is what kills most DSL availability is not only the length but the voice coils they use on the line to provide your voice service. The DSL signal and the voice coil don’t like each other.
Now that said here is what to expect from our DSL services.
For home users and very small offices ADSL or Asyncronous DSL is your best option. ADSL provides an effective speed from 384k to 3 Megs depending on the option you choose. Now these are download speeds only. If you send files such as large e-mails or want to serve your own web content the upload speed is what will concern you and is much lower on an ADSL circuit than the upload speeds. ADSL circuits are also non-dedicated which means you must login to the internet in order to activate your circuit.
For small business or active homes we recommend SDSL service. SDSL circuits are syncronized for identical speeds both upload and download and most resemble the more expensive T-1 line. With SDSL service phone service is not required. We bring our own lines to the location and make our own loops. With SDSL we can extend the range up to 22,000 feet and still have access. While not as fast as a 4,000 foot loop still it is broadband. Speeds range from 192k to 1.5 megs depending on your distance and the plan you choose. SDSL is good for VoIP or Vonage use.
Can’t get other DSL services? IDSL may be the way for you. It has syncronized up and download speeds and is still faster and less expensive than ISDN. With loops up to 35,000 feet you are almost assured of being able to qualify for this service. IDSL is not recommended for VoIP / Vonage use.
