DSL Facts

What is ADSL vs. SDSL vs. IDSL vs T1?

ADSL stands for Asymmetrical Digital Subscriber Line. This means that the speed is different in both directions. For example, one of our Residential speed options is 608/128 Kbps. This means the transfer speed down is 608 Kbps (kilobytes per second) whereas the speed up is 128 Kbps. ADSL is ideal for home use and general surfing. Since you are the only one accessing the information, the speed in which you receive the data will be much quicker.

SDSL stands for Symmetrical Digital Subscriber line. Unlike ADSL, the speeds for Symmetrical Digital Subscriber Lines are synchronous. So regardless of the speed chosen, transfers will be the same in both directions.

This type of service is an ideal choice for businesses. One reason is that customers pulling information from your site will actually receive it at a much faster rate. Secondly, the service comes with a high-speed router, which is already set up for running multiple computers. The router also includes other advance features such as a built in firewall, and VPN capabilities.

IDSL is basically ISDN. It is ideal for those customers who are too far from our Telco switch to obtain either ADSL or SDSL services. The speed on this service is symmetrical, but it is fixed at 144 Kbps. This service also comes with a high-end router capable of networking several computers.

T1 is based on a industry standard technology used to access the Internet at speeds from 384K to 1.5M. T1 is a far-reaching, fast access solution designed for businesses with high bandwidth needs that were previously unable to qualify for DSL service or a necessary DSL speeds due to distance or technical limitations. This service also comes with a high-end router capable of networking multiple computers.

Self-Installation Information

The use of self installation kits allows you to obtain TeleSurfer and TeleSoho services in a much more cost effective manner than having a technician visit your premises to complete the installation. The self installation utilizes an easy 3 step process to guide customers to a successful installation in under 30 minutes.

What comes in the self installation kits?

• DSL modem or router (depends on the service you order)
  These devices connect your computer to the Internet using DSL.
  
• DSL blockers
  Also called In-line filters and micro-filters. This device plugs into the telephone jack and is used to separate your voice signal from the DSL signal on the same line.
  
• Y-Adapters
  The Y-adapter is a device that is plugged into a telephone jack. This allows telephone equipment and the DSL line to run through the same jack.
  
• Telephone Cable
  This cable connects the DSL modem or router to the jack.
  
• Ethernet Cable
  This is the cable that connects your computer to your DSL modem or router.
  
• Instructions and Troubleshooting Guide
  These documents will walk you through the entire installation process, and help you solve any problems that might come up along the way.
  

What do I need to know about self installation?

As with line sharing, there are specific technical limitations of self installation. If any of the scenarios below apply to you, you will need to pay for a professional installation. A technician will be sent to your home or business to complete the installation.

Do you have a security or health monitoring alarm connected to your phone line? If you have one of these devices connected directly to your phone line, meaning that it is not plugged into a phone jack, you will need a Professional Installation. A technician must visit your premises and install a device (a DSL splitter) that physically separates the analog voice signals from the DSL signal.

Do you have more than 5 devices connected to your phone line? If you have more than 5 devices (telelphones, fax machines, satellite or cable box, etc.) connected to your phone line, you must have a Professional Installation. A technician must visit your premises and install a DSL splitter.

Here are the five facts you should know about DSL Internet access. This service is:

Remarkably fast
With DSL service, you can benefit from Internet speeds that are up to 12 times faster than a typical ISDN connection and 50 times faster than a traditional 28.8 Kbps modem. This means that in the 12 seconds it takes to read this information, you could have downloaded a 2 megabyte presentation file or web photograph. It would take 10 more minutes (600 more seconds!) to download the same file with a traditional 28.8 Kbps modem.

Highly reliable
You can depend on DSL because its proven technology takes full advantage of the existing telecommunications infrastructure. And you can count on DSL to scale with your future connectivity needs. That's a level of comfort you won't find with other Internet access technologies.

Inherently secure
Because our DSL network provides a dedicated Internet connection via private telephone wires, you can bypass dial-up intruders or shared network hackers. Unlike traditional dial-up modems or cable modems, DSL protects your valuable data with the most secure connection available.

Surprisingly affordable
DSL is widely recognized as the most cost-effective connectivity solution for small businesses. DSL delivers industrial-strength T1-like speed (as fast as 1.5 Mbps) to multiple users at only 25% of typical T1 costs. There's no better price/performance option available.

"Always on"
DSL is ready to run, every minute of every day. There's no more logging on and off, no more busy signals or disconnects. This gives you the freedom to focus on what you want to accomplish online - rather than focusing on trying to get connected. In fact, you can be more productive because the power and immediacy of the Internet is continuously available at your fingertips.
