DSL - How It works

DSL will be the primary data products for companies with less than 6 phone lines. DSL is an affordable way to process data – key in the restaurant business – and to use email and other web services. Below is a generic overview of DSL.

DSL stands for Digital Subscriber Line. DSL is a technology that uses a standard copper two-wire pair (or line) to transmit high speed (high frequency) Internet connectivity to areas that will support the service.

Can I get DSL in my area?
DSL service can only be delivered within a radius from your phone company's local central office. Typically, the highest speed service is restricted to a distance of 15,000 feet from the central office it is served from.

What are the different DSL "Options"?
The speeds and type of DSL available to you depend on two factors primarily: 1) Your distance from the phone company's Central Office (CO) and 2) the type of lines used between you and the Central Office (fiber/copper). Each type of DSL has a different price, and different important attributes.

ADSL
Asymmetric Digital Subscriber Line is best for home and small business users based on price and speed. It is called asymmetric because more of its bandwidth is devoted in the downstream direction than in the upstream direction. The main reason for this is most Internet applications require high-speed Internet download bandwidth while user requests and responses are small and require little bandwidth. ADSL runs anywhere from 608Kbps to 1.5Mbps downstream and 128Kbps to 384Kbps upstream. ADSL is available up to 15,000 feet from a CO. Typically the download speed is faster than the upload speed. While ADSL can generally be installed up to 15,000 feet, this general rule does not guarantee that we will be able to install the circuit or that the circuit will perform at a reasonable level. Our ADSL service is also referred to as RADSL (Rate-Adaptive ADSL).

The term "rate-adaptive" means the technology adapts to your individual line conditions, e.g., your specific distance from the CO and the quality of the copper line that serves your DSL. Speeds expressed with ADSL packages are the maximum speeds your line may achieve. Although we will do everything within our power to provide you with the best possible service, due to the nature of the technology, ADSL services do not come with a service level guarantee. The actual speed is determined by both distance & copper quality, and installations resulting in "best business effort" speed (the maximum achievable speed based on technical conditions prior to install) will be considered successful. As many businesses require a guaranteed service, ADSL is not available for business locations. We recommend SDSL service for all eligible businesses.

SDSL
Symmetric Digital Subscriber Line is best for heavy home users such as gamers, and for commercial customers. SDSL uses a single twisted-pair line, carrying 1.544Mbps in each direction. It is called "symmetric" because the data is the same in both directions, downstream and upstream. ISPs provide different service plans based on the data rate; they range from 192Kbps dedicated to 1.544Mbps dedicated. SDSL will support small and medium sized businesses. SDSL solutions start as low as $90/month. SDSL can be served up to 15,000 feet from a CO.

IDSL is based on ISDN, an older technology that was designed to work well with existing ISDN transmission methods. SDSL, and ADSL travel over regular copper lines and cannot have any electronics on them (such as, for example, amplifiers or repeaters - commonly used to "boost" the voice signal on conventional telephone lines). Some ADSL, and SDSL orders cannot be fulfilled because of electronics or distance issues that are uncovered during the ordering process. In that case, IDSL may be the best solution. IDSL has the ability to work over great distances, and through certain types of electronics. If you are very far away from a telephone CO (Central Office), or there are electronics on the copper line you are given by your phone company, you may still be able to get broadband service using IDSL

Satellite
Compare high-speed Internet providers for Satellite Internet service. Satellite Internet service is ideal for those who cannot be reached by other Internet connection types. Satellite Internet has come a long way since its conception and now is more reliable than ever. It relies on geostationary satellites that orbit above the equator at the same speed as the earth’s rotation and, thus, appear to be stationary to the ground. The introduction of increased bandwidth capabilities through the use of broadband technologies and IP spoofing techniques allow these satellites to be used for high-speed Internet access. The average Satellite download speed is 400Kbps although the Satellite can run up to 1.1Mbps. This will be more than sufficient for most Residential or small Business Internet users. As long as you have a clear view of the southern skies, you can get Satellite Internet service. We offer Satellite Internet service for as low as $59.99/month.

Cable Internet
Cable is best for home and small business users based on price and speed. Cable lines run over the cable providers existing cable through a cable modem. A cable modem can run at high speeds, with a maximum of 2 Mbps download, typically running between 500 Kbps and 1 Mbps, and with uploads between 128 Kbps and 500 Kbps.

T-1 Overview

-1
T1 is a solution for business that have more than 20 using the internet or businesses that utilize significant voice and data applications. T1 is a term for a digital carrier facility used to transmit DS-1 formatted digital signals at 1.544 Megabits per second. A T1 is made up of 24 digital channels. Most small Internet providers have a T1 line as their connection to the Internet. A full T1 should accommodate from one to over 200+ users and other services from an Internet service provider (ISP).

T-3
T1 is a solution for business that have more than 200 people using the internet or businesses that utilize significant voice and data applications. T3 is a group of 21 T1's combined together to form a circuit. This T3 circuit is capable of 44.736Mbps both upstream and downstream. Fractional T3s are available to those who need high speed internet downloads and uploads faster than a T1 but who do not need a full T3 line.

Fractional T1
Fractional T1 is best for commercial customers that need serious bandwidth, but not a full T1. T1 is a term for a digital carrier facility used to transmit DS-1 formatted digital signals at 1.544 Megabits per second. A T1 is made up of 24 digital channels. Most small Internet providers have a T1 (or a fractional T1) line as their connection to the Internet. A full T1 should accommodate from one to over 200+ users and other services from an Internet service provider (ISP). For those whom a T1 is not necessary, fractional T1s are available at a lower cost. They simply use a fraction of the total channels available for a full high speed internet T1 line.

Integrated T-1
An Integrated T1 is a great new and popular service that allows you to combine all of your voice and internet requirements on one T1. This solution is perfect for business with 5 + phone lines. These solutions start as low as $339 a month. This is the solution that the traditional phone companies don't want you to know about.
