DSL & Cable #3
Posted by Joseph Brochin
Now, I would like to address cable access to the Internet.
During the last few years, the cable companies have focused upgrading its existing infrastructure in order to deploy high-speed Internet access and VOIP over cable for homes and businesses.
It has started to become a user-friendly household source of affordable broadband Internet access for millions of people.
Residential users are the consumers who receive the most benefit from this technology.

Due to the current inherent limitations of cable technology, it is not usually a viable solution for businesses.
These limitations include, but are not limited to the following:
Wiring (most businesses are not wired)
Congestion and delay (the more people using cable, the slower the service)
“shared” connectivity, security (your neighbors may be able to access your files),
Cable’s inability to support any type of web or email server.
Ultimately as cable grows in popularity small businesses will and are making the mistake of seeing cable as an alternative to DSL.
This is not the case and should be studied carefully and a business should seek the advice of an IT and Telecomm solutions provider and consultant.
What is DSL (Part 2)
Posted by Joseph Brochin
In my post “What is DSL?”, I briefly discussed DSL.
We ended the post with a bulletized list of advantages and disadvantages of DSL.
I concluded with the last stated disadvantage of availability of DSL.
So first we will discuss the effect of distance on DSL and why this limits the availability of DSL.
DSL is a distance sensitive technology. As distance increases speed decreases.
The limit for ADSL, which is what most residential customers have, is just over 3.1 miles or 5 kilometers from the central office.

Now, most people misinterpret this as being the distance from the brick and mortar phone company where they pay their bill.
Most of the time this is incorrect.
The central office can be something as simple as a little brick building by itself that contains switches and other equipment. It can also be a janitor’s closet that is rented by the phone company.
So disregard the distance to your provider’s main office as criteria for this determination.
Online tools, like those found at www.brochin.net, take some of the guesswork out of figuring out if DSL is available at your location.
Tools like the ones available at Brochin.net will also provide you a list of DSL providers for your area and their rates.
There are not too many areas that are near urban environments that do not have the ability to receive DSL service.
