DSL filter kit

Most of us connect to the Internet using wired broadband connections provided by our telephone provider. The stability and speeds offered by the single pair copper cable, that carries both Voice (required for phone communications) and Data (required for Internet browsing) has been getting better with each passing day. 

One of important reason for the phenomenal success behind broadband Internet connectivity is its ability to allow simultaneous voice sessions along with data sessions. So, one can keep talking on the phone while others are browsing on the Net. Along with the higher speeds offered by broadband, this simultaneous utility (of voice and data) is an important reason for its instant popularity.    

One needs an DSL/ADSL Splitter that accepts the combined voice+data signal offered by the telephone provider, to split it in to voice signal and data signal. These two signals are offered to the user in two separate output ports. The connection from one port goes to the telephone instrument and the other, goes to the computer through the DSL/ADSL Modem.  Of course, both of them can be accessed simultaneously.

But, there is one issue though. Sometimes, when we are talking on the phone we tend to hear some disturbance (noise) if the Internet connection is being used by someone else. This is a bigger issue for people who have multiple phones in their house (set-up in parallel). 

Even though certain DSL/ADSL splitters can filter out the data signals from the voice port, they are limited to the one phone that is connected directly to them. Besides, some DSL/ADSL splitters cannot fully filter out the data signals (on the voice port). 

There is another issue: What if there are a few phones connected in parallel? Or, what if there is a fax machine connected in parallel? 

That's why one needs an DSL/ADSL Filter. The DSL/ADSL filter, filters out the data signals from the voice signals and drastically reduces the interference (disturbance/ noise) on the Telephone, when both voice signals and data signals are received simultaneously. 

Actually, the DSL/ADSL filter contains an analog low-pass filter circuitry that eliminates high frequency data signals. 

The commonly available DSL/ADSL filters are In-line devices that accept the phone-line input (from the service provider) on one side and plug the line going to the telephone instrument, on the other side. An DSL/ADSL In-line filter  needs to be positioned just before every phone/ fax machine in order to eliminate the noise/ disturbance one gets to hear (while speaking), when an Internet connection is in progress simultaneously.      

What about wall mounted phones? One cannot connect this DSL/ADSL filter behind wall-mounted phones right? Yes. But, there is a separate DSL/ADSL Wall-mountable Filter that can be attached just behind the wall mounted phone (actually mounted in-between the phone and the wall jack) and the phone can still be hanging on the wall from over the DSL/ADSL wall-mountable filter, in the same way as it was before!  

There is only one thing that is missing to complete the connection – A Phone-cord that connects from the voice port of the splitter to your telephone. 

The Alcatel DSL/ADSL filter kit (DSL/ADSL filter + phone cable + wall+ splitter 1xRJ11 to 2xRJ11) contains all the above mentioned items as a package, so that a customer can get the best value out of it, and remain free from all distraction/ noise while talking to someone on the phone.
