Vpn Broadband passage (Cable and Dsl)

What Is Broadband?

Broadband technologies furnish high-speed passage to the Internet. These technologies are an alternative to dial-up methods that use a original analog modem.




The major broadband technologies are:

  • Cable Modem Service

  • Digital Subscriber Line (Dsl) Service

Cable modem services use the same coaxial cable or fiber optic line that brings cable television into your home. A cable modem connects users to the Internet by means of the cable company's network. Because of its excellent bandwidth capacity, cable modem delivers greatly enhanced speed to users.

Dsl services furnish a high-bandwidth connection over the same wires that furnish your telephone service. Since Dsl uses a separate frequency than the phone service, you can use the same line to make phone calls while your Pc is connected to the Internet.
With both of these broadband technologies, your Pc is always connected to the Internet.

Should I Use Broadband?

The high-speed, "always-on" Internet passage provided by broadband technologies offers sure advantages. And broadband might particularly benefit you if:

  • You need to be connected to the network for many hours a day from a fixed location.

  • You have large downloads/uploads to process on a quarterly basis.

  • You are a virtual employee who cannot get a trustworthy phone connection with a decent speed.

However, there are number of issues to think when choosing if broadband is right for you:

Availability Cable modem or Dsl services are not available in all locations.

Cost Broadband passage is ordinarily more expense than dial-up service. Prices typically range from to monthly depending on your area, your provider, and the exact type of service you need.

Security With a cable modem or Dsl line, your Pc is always connected to the Internet with a persistent Ip address. Since this makes you a potential target for hackers, your Pc should be secured by a firewall.

Portability Cable modem and Dsl services are not portable. For example, you do not take them with you when you travel. If you need to passage your network while traveling, you might need a separate dial-up Isp.

Comparing Cable Modem and Dsl

Which is better, Cable modem or Dsl? There is no simple respond to this quiz, as each technology has its advantages. Indeed, local availability of these technologies will often decree which service you choose.

The following compares the two technologies on some key characteristics.

Cable Modem

  • Requires a cable connection.

  • Generally faster speed than Dsl, but throughput can vary.

  • Cost relative to Dsl varies based on location.

Dsl

  • Requires a telephone line connection.

  • Generally slower speed than cable, but provides a more constant throughput with lower latency.

  • Cost relative to cable varies based on location.

More About Cable Modem Service

Cable modem service can be a particularly appealing selection if you already have cable Tv service or if you use only cellular phone service at your home.

Finding Cable Modem service Providers

To find out if cable modem service is available in your area, start by calling your local cable Tv company. Be aware, however, that some areas have more than one cable Tv company. One supplier might offer cable modem service, while the other does not.

Installation Issues

Typically, you will need to deal with only one vendor (the cable company) when installing cable modem service.

Some providers wish that a service technician come to your home to setup the service and setup your computer with suitable software. Other providers give you the selection of installing the software and setting up the cable modem yourself.

In whether event, you should be aware that:

  • Not all cable modems work with every service provider. Before you buy a modem, check with your supplier to see which modems they support.

  • Even if cable Tv functions in your home, you might not be eligible for Internet cable passage if the line potential of your coaxial cable is too weak.

If you decree to setup the cable modem yourself, be sure to:

Ask your cable business what kind of splitter to use. (In many cases, the cable business will furnish you with a splitter.) When purchasing a splitter, ensure that it provides Emi isolation, and that it has sufficient frequency range (approximately 5-1000 Mhz). The range should be printed on the splitter.

Place only one splitter in the middle of the point where the cable Tv line enters the house and the cable modem/Pc. If you have multiple Tvs, split the line in the middle of the first splitter and the Tv--not the line in the middle of the splitter and the modem.

Do not use amplifiers in the line foremost to your cable modem as they are likely to distort the cable modem signals.

More About Dsl Service

Dsl is provided in a variety of exact service types. Some examples consist of Adsl, Idsl and Hdsl. Sometimes the generic abbreviation Dsl is used to collectively rehearse the assorted types.
Dsl is an "always on" direct connection to the Internet usually made straight through a router, bridge, or Dsl modem.

Finding Dsl service Providers

A good place to check for Dsl availability in your location is the broadbandreports.com web site. Go to the Find service function and be sure to pre-qualify the area in which you live. This site can give you an idea of what vendors maintain your area, how far you are from the provider, what types of Dsl and options are available and approximate prices.

You should be aware, however, that a supplier might select not to maintain an area due to issues other than distance. This can be the case even if you successfully pre-qualify your area for Dsl service.
Also, not all providers are listed on this web site. Therefore, you might want to check the other links listed in this topic as well.

Installation Issues

Typically, you will need to deal with three vendors (the phone company, the Dsl provider, and the Isp) when installing Dsl service. Even if your phone business is serving all three roles, they are usually separate divisions and communications in the middle of them can sometimes get confusing. Generally, the Isp is the designated point of contact.

As previously stated, the Dsl service typically shares the copper phone line that you already have installed in your home. However with some types of xDsl (such as some Idsl implementations) do not always offer concurrent phone services on the Dsl line. You should check with the Isp or phone business providing the service. In any event, Dsl service can be configured to run on its own separately installed line.

Your Dsl supplier will set up a time for the phone business to turn or setup the line for Dsl support. Sometime after the phone business completes this task, the Dsl supplier will setup and test the inside wiring and equipment. Then your Isp should sense you to setup the mail and other extra requirements that you may have.

When installing Dsl service, you should be aware that:

Your Dsl supplier might need an Ip address supplied by your Isp to properly test the line. Be sure the required Ip address is obtained prior to premise time.

Dsl installations do not always go smoothly, and delays in premise are not uncommon.

Installation problems can sometimes only be resolved effectively by getting all the parties complex together (such as straight through a argument call).
