With plenty of internet connection types available in the market these days, it can be hard to choose the one that best suits your needs. DSL is one of those options, and it is highly popular among internet users throughout the nation. With broadband revenues climbing steadily, there are tons of potential clients for companies selling DSL internet service. Let us see what DSL is before you go ahead and sign up for it.
DSL is short for Digital Subscriber Line, and it uses different technologies to bring internet access to customers through the transmission of data via telephone wires. In telecom, the term DSL is used to refer to ADSL or asymmetric digital subscriber line. The latter is the most commonly used among the DSL technologies in existence today. There are other options to be had as well, and what you get changes with the service provider you choose to sign up with.
PPPoE stands for Point-to-Point Protocol over Ethernet. It is a specification that links different users who have a connection over Ethernet local networks. The PPP protocol is part of the Ethernet frame. Simply put, the user logs in to network with a username and password, and gets provided with an IP address that lets them browse the internet. Many ISPs favor this setup because the it assures fast service deployment, while keeping the costs low for the client. PPPoE supports more than one existing service and application, which allows controlling the internet connection without the need to remove a wire or make a software change.
DSL and cable internet could not be more different. Where cable makes use of coaxial cables (yes, the same ones through which people get cable television in their homes) and send digital or analog signals through these, DSL utilizes the phone line to transmit digital signals in the direction of a DSL modem. This produces some difference in the bandwidth available with both options. While cable internet is faster, DSL offers the benefit of not having to share a line. On a cable network, congestion can be an issue, often meaning slower speeds. DSL, meanwhile, maintains a feed and has lower latency.
DSL service comes with a dedicated line. This gets rid of many of the problems associated with shared lines. We already mentioned that with cable lines being shared, the connection they provide could be slowed down as a result. Even with a higher potential speed, it would give you a hard time hitting that maximum. DSL does not put you through that; it promises and delivers the exact same thing – a dedicated connection that only you are using, and speeds resulting from that scenario.
DSL is very fast, especially compared to modem connections and most other internet options. Your typical modem gives a connection speed of 48 Kbps (this is slow), while a standard DSL connection offers around 1 Mbps in terms of speed, and that is more than 20 times faster.
Back when internet connections started out, you would not have been able to use the phone and the internet both at once, and some people still believe this to be the case. This was only the case with regular modem connections, however; DSL does not have that issue. Different frequencies are used for phone and internet, which means you can use both simultaneously.
DSL stays on all the time. After you connect your computer through PPPoE, you can go to town browsing the internet. Where a couple of decades back dial-up would have had you wait till a dropped connection was set back up again, DSL offers a welcome contrast with a continuous online experience.
DSL is unsafe without firewall protection, and it is important to make sure that you have an active firewall to keep out intruders, who would otherwise find it easier to get in since you are constantly connected. Cable internet has the same issue. A firewall is doubly vital if you make use of a wireless switch to connect through PPPoE.
Many people think that DSL service is available in every place that a phone line is installed. This is not fully true. Phone providers do not all sell internet services, so it is important to ask around and find out what options the different ISPs are offering in your neighborhood. If the place you live is really remote, installation costs for DSL can be through the roof. Additionally, it is a requirement that the phone line reaches your home or office for you to be able to go online. In rural America, for example, you may have not other go than to get satellite internet instead.
DSL is the perfect choice for businesses and offices. Such places need fast, uninterrupted internet that lets people do their work without experiencing lag or high latency in the connection. DSL is also a good fit for gamers, again because of the fact that it has low latency. People wanting really high speeds are likely to opt for faster options such as cable internet, but the latter does come with the issue of slowing down under heavy traffic. Internet games do not do well on slower connections, which is why DSL is a better bet.
If you have an established phone line at your home or office, and if the service provider you are in contract with is also giving internet packages, then that is a point in favor of getting DSL. The benefits include fast installation, as well as not needing to add any more cables to the existing setup.
When you get right down to it, it is all about preference. You can easily choose DSL if you are looking to get internet for a business, because it has the basic benefit allowing simultaneous phone and internet use. Additionally, DSL offers higher prices at lower rates than the other internet options available in the market today.
