One thing to keep in mind is that a DSL connection is different than a dial-up connection. This is because it does not occupy your phone like even though it shares the telephone line. By sharing the line and, a DSL device offers a much faster connection than the older dial-up method. It is way more efficient.
The DSL connection sends digital signals where your telephone sends voice signals. It makes use of the unused wires in the line for transmitting the digital signal. This is the main reason why you can use both your telephone and internet connection on one line. If you do not use a splitter, you will get better quality in the connection by installing the DSL filter as the wires are so close to each other.
A DSL filter, also known as a micro-filter, is an analog low-pass filter between analog devices and a regular line for your home phone.
So the question is if you really need a DSL filter. It comes in very handy due to various reasons as mentioned below:. This is because the same line can disrupt your DSL internet connection. Thus, it eliminates signals or echoes from an analog device from compromising performance and causing connection issues with DSL service.
You will need DSL filters installed on every device that connects to a DSL phone line especially if you are using a home phone service without a splitter setup. As mentioned before, equipment such as phones, fax machines, and regular modems tend to disrupt the telephone wiring when they are being used.
This leads to disruption with the DSL signal over phone lines which eventually results in a poor connection and it can even interrupt DSL service. This persists as long as you are sending faxes, using the modem, or talking on the phone, etc.
Now, this is where a DSL filter plays its part. What does it do? It basically filters out this blockade so that you are able to freely use your phone without worrying about it interfering with the DSL signal.
Another reason why DSL filters come in handy is that they keep the high-frequency DSL signal from reaching your other devices such as phones and fax machines etc. This is because if these signals reach those devices, you will be facing numerous issues such as irritating phone calls or slow regular modem speeds. Even though the benefits of DSL filters are endless, there are some limitations too.
Firstly, you need to keep in mind that there is a limit to how many filters you can use, which are generally 4. This is because if too many filters are used at one time, it can again cause disruption with your phone line, and eventually, the disruption will start to interfere with the DSL signals as well. The best thing to do is to use a whole-house splitter.
This, in turn, prevents the need for a filter at every phone. However, this becomes costly and time consuming for the phone companies as they have to send technicians to install the splitter and rewire a few of the phone jacks in your house.
Therefore, they just send you more filters that you put on all your devices. However, as mentioned above, this is not suitable, and using a whole house splitter is a much better idea.
You can purchase these at any electronics store. How do I install a DSL filter? Need additional filters? Please contact our Technical Support Team.
What if I have a wall mounted phone? There are two methods for installing DSL service: split, or splitterless.
A DSL filter is not required if the split method is used. In this case a technician visits the premises and installs a splitter in the main telephone cable. Two lines emerge from the splitter; one line feeds into standard phone jacks, while the other line is used exclusively for a DSL modem. A DSL filter is not required in this case because the splitter has separated the voice and data signals.
The second method, which has gained popularity because it does not require a technician, can be user-installed. In this case, the end-user can setup a DSL modem along with several micro-filters. DSL service is sent through the main service line so the end-user only has to connect the modem to any existing phone wall jack.
