What
you should know
about RDSL
RDSL service is delivered over a standard telephone line. Many factors influence the delivery and performance of this product.
We encourage you to familiarize yourself with the following information so that you know what to expect during the provisioning process!
How DSL works
RDSL uses proprietary technology to put data on your POTS telephone line. High frequencies carry data, and the lower frequencies carry voice conversations. Thus you're able to talk on the phone and surf the Internet at the same time.
LISCO works with the telephone company to provide you with this service.

Telephone lines
Not all telephone lines can support RDSL service. LISCO will pre-qualify your line for you before you order service.
You will be contacted by email with your results, after you submit a pre-application with us by phone. Please feel free to call us if you have questions about them.
NOTE: The pre-qualification is a preliminary finding, because, although rare, a passing line may later be discovered to be unsuitable.
Data noise
When you order DSL, you’re authorizing us to place data on your telephone line. Data uses the high frequency portion of your circuit, and noise from it will be audible on all your extensions.
To remove this noise, you will need to install noise filters on each extension of the line your DSL is on. If you order your modem from LISCO, it will come with two noise filters included.
Phone wiring
The portion of your phone line tested is the portion between your house and the telephone switch. The wiring inside your house is not tested.
Please remember that LISCO is not responsible for the condition or suitability of the telephone wiring inside your location.
NOTE: Some wiring, which is fine for a normal telephone, will become very noisy when DSL is added to the loop. For a few customers, the services of a qualified telephone wiring professional is needed. Extra wiring expenses are not included in the fees you pay to LISCO for your DSL service.
Other Considerations
We recommend that DSL be ordered on line 1 of any multi-line jack, for ease of installation.
DSL will work on a line that goes through a phone system like a PBX or KSU, but additional inside wiring may be required at your own expense.
Computers and network equipment
Your computer will need to have an Ethernet (NIC) card installed. You can get one by calling your computer manufacturer or local computer store, or from us.
You are responsible for setting up and maintaining your LAN (local area network). We will help you troubleshoot it over the phone if you are having trouble related to your RDSL connection, but please bear in mind that we cannot possibly be familiar with every type and configuration of equipment out there!
We sell a variety of LAN equipment, like NIC cards, hubs, firewalls, and more! Just visit the Store section of this website, or give us a call.

Viruses and firewalls
We strongly recommend that you keep your network protected by both a firewall and by virus protection software. With a DSL, you are always connected to the Internet, and that makes you more vulnerable to attack.
If your data is mission critical, you not safe on a DSL connection without a firewall and virus software!
Software firewalls are recommended for single-computer networks, and hardware firewalls are recommended for those of you with more than one computer on your DSL connection.
NOTE: Virus software and firewalls are not included in your RDSL service fees.
