Talk:DSL filter

From Wikipedia, the free encyclopedia

why is this forwarded from DSL splitter? Aren't a DSL splitter and a DSL filter different?

A DSL splitter is just a regular phone splitter with a filter on one of the outputs. I think they are the same, in so much as they should be on the same page, because they are basically the same topic. However, it could be said that some more explanation of the diff between a filter and splitter should be added to the topic. Jrouvier 08:38, 16 July 2006 (UTC)

Actually, a DSL splitter contains 2 filters: a low-pass filter on the POTS output and a high-pass filter on the DSL output. JanCeuleers 17:01, 16 July 2006 (UTC)

I think it should be lined out, that each analog phone, fax, ... needs to behind a filter. So you may need more than one filter.

In most cases you need to supply a filter for each outlet (except the one where you plug in the DSL).

In rare cases you will be able to intercept the analog singal where it enteres the house or flat, split it up into a filtered and an unfiltered signal. The filtered signal is fed back into your existing cabeling, the unfiltered signal is connected to the DSL.

In Germany it seems you have to use a splitter. All manuals about installation of DSL tell you to use a (=one) splitter and there is no mention of using several filters for analog devices. I have also seen online shops that sell "filters" for some countries in the EU, but not Germany. Am I getting this right? Is there a reason why it seems to be prohibited to use filters in Germany? -- 91.7.159.200 11:27, 25 March 2007 (UTC)

Given the high penetration of ISDN in Germany, DTAG has decided to standardise on the ADSL-over-ISDN variant, regardless of whether a particular subscriber uses POTS or ISDN. A simple filter at the customer prem isn't enough to keep the ISDN signal from interfering with the ADSL signal, so a full-blown splitter is needed. JanCeuleers 15:43, 25 March 2007 (UTC)

re: Other problems which have been reported by users are the failure of their telephone to ring when receiving an incoming call

Where does this come from? I added {{Fact}} to this

I work with these things and I've never heard of it. They generate the ring notification from the incoming signal lines, just need a capacitor. So, can you cite a source for this statement? 192.118.34.229 09:19, 6 August 2007 (UTC)

This does happen to me. I have no idea why though.125.27.197.204 17:33, 31 August 2007 (UTC)
