An ADSL Inline Filter/Splitter

Does your ADSL drop out when phone rings?

Are you having dropout problems with your ADSL when the phone rings or when you pick up to the phone to make a call? These sorts of ADSL drop outs are typically caused by issues the ADSL line filtering.

The ADSL Line Filter/Splitter is a low pass filter that separates the voice and data parts of your phone line. Sounds sent down the phone line above the frequency of normal human voice are blocked on the ADSL side of the filter. Frequencies used by ADSL are blocked on the phone side of the filter. If there is no filter or the filter is faulty the frequencies from your phone will interfere with the ADSL causing it to drop out.

Prevent ADSL Drop Out

These ADSL dropouts can be prevented by installing Inline ADSL Filters on every phone on your line. If you already have filters in place on all phones, it may be necessary to replace them because one may be faulty. One method of finding the faulty one could be to get a new one, and swap it with the existing filters one at a time and then picking up that phone. If you’re able to do it without the ADSL dropping out, you’ve found the one that was faulty.

ADSL Filters can be purchased from the Digital TV Help store.

The best way to solve this problem is to install an ADSL Central Filter. A central ADSL splitter/filter will mean that your phone sockets don’t require their own individual inline ADSL filters. An additional socket will be installed at the location where your ADSL modem sits, just for the use of the ADSL modem. Not only does this reduce the issue of drop outs, but it also can improve sync speed of your connection.
