What Is A DSL Filter?


DSL filter is an analog, which is installed on the telephone lines or some other type of analog devices, to ensure outside interference is prevented when DSL services are functioning on one line. It is imperative to install a DSL filter as without this the connection can have major performance problems.

Most of the time, every telephone and/or fax machine line will be equipped with a DSL filter and only the cable connection will be left without it. Many people split the telephone line keeping one line for the DSL modem and the other for all the telephonic contraptions.

There are many devices with specific uses such as special telephones for the deaf that are not functional with a DSL filter. For these situations, a separate line will need to be obtained.

How It Works

As long as the DSL filter is installed, the analog low pass filter will ensure that the signals are not interfered with by any outside noise or higher frequency signals. Unless this is installed on the telephone wire, you will find connectivity problems, as well as buffer sound and gurgling noises in the background, to name a few problems. When the telephone wires and the DSL modem line are separated, then this problem is avoided to a large extent. This is one of the main causes why some people prefer the cable to the DSL service.

In this aspect the cable is much better. You just connect and use it. You need not worry for the frequency, filters, other connections, signal interference and so on. In this way, the cable seems much more reliable and suitable for continuous and heavy surfing. However, this is true more in theory than in practice. In reality, the cable also can be pretty unreliable; its unreliability however depending largely on the efficiency of the provider and the maintenance it provides to the customers and his equipment. Cable internet is extremely fast and reliable as long as the maintenance is done well and regularly.

For those who use the DSL filter correctly, there should be no complaints since this is a very safe, fast and secure way to surf the Internet. However, the initial trouble for installing it and get work at optimal level sometimes can be a heavy deterrent factor. Nonetheless, there are more and more people who are recognizing DSL to be as effective if not more effective than cable.
