DSL Overview
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?
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.
How fast is DSL?
DSL can obtain speeds as
high as 1.5Mbps and above, but the speed your location
can receive depends on your address, line quality and
the distance to your local phone company's central
office (CO). A Central Office is the main switching
station for the phone lines in your area. It is the
office where the ILEC (your local telephone company)
connects the phone circuits, and makes the routes
between local and long distance.
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. Fill out
our Dsl availability form for more information on
Satellite Internet and our other high speed internet
solutions.
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
T-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.
