please tell me why i dont need a broadband filter on my digital phone when on the net but i need one on my ordinary telephone thanks

I don't know the exact answer to this, but based on what I know I could make a good guess.

A broadband internet connection essentially sends and receives it's data in pulses, millions of times a second. This is binary data which is digital. As a result, I'd imagine that a digital phone doesn't have to use a filter to send it's data through the line in the same way.

However, since normal telephones are analogue and do not send their data in the same manner and/or format, a filter on the line has to be applied to filter the data into the correct fromat, much in the same way that a dial-up modem would have to convert digital computer data into an analgoue signal.

That is by no means fact, but it makes sense to me and if anything I don't think I'm too far off the mark.

..might not be anything to do with the type of phone but with the way your set up is connected...out of curiosity just try plugging the phones into the others sockets if that is possible....just a thought.

to commoner re your comment to explain      main phone    is fitted to  filter in the socket   the other phones are extensions   i can put digital phone in and broadband okay but when i put an ordinary phone in broadband  cuts off  when answered this is why i thought it would be better to buy another digital phone for upstairs extension  hopes this explains myself a bit better

I've totally the opposite problem, my connection keeps dropping out when I answer my digital phone. Anyone got any ideas how to fix this problem? I have filters on each telephone point. thanks

...the broadband filter(splitter) which you should have been supplied with must be plugged DIRECTLY into the MAIN telephone socket..(this will have a special socket for the broadband and a telephone socket ) then the broadband modem and telephone both plug into that filter (splitter).....Putting a two-way phone adapter into the MAIN telphone socket first, then taking your modem and telephone seperately from there will not work....at least not on my stuff.... if you want two phones use a two way telephone adapter AFTER the filter....commoner.

Hope that's clear....

to commoner    yes that is right and that is how i have my main phone   it is the  extension in kitchen that was the problem digital phone works without a filter there but ordinary phone needs filter   just thought i would  reply in case it helps someone else  

[commoner]

..hmm....sorry we don't seem to be on the same wavelength, but if both your phones worked before you got broadband and they and the ADSL modem are plugged in correctly, they should still work ok now.....The filter *** splitter is designed to keep your phones and modem apart.........sorry can't explain my point any clearer..........:-(

...I use Wanadoo by the way.

to commoner  perhaps i am not explaining myself  properly   yes   phones worked   ok  before   broadband .  my main phone socket   is in lounge  and into  that  is broadband  filter with 1 ordinary phone and modem connection    then   i have an extension  from that to dining room now in  that  socket i can put  a digital phone in without filter  and bband is   ok  but when i put    an  other ordinary phone on that extension it does not work  i  just wanted to know   why i didnt need a filter on   the digital phone   the ordinary   phone does work with filter   ineed to buy  another  phone    so instead of buying another  filter i would be just as well buying another digital    have i got your head  spinning maybe it is because i am a woman

[commoner]

..lol..well I should have known better than to try to convince a woman of something once she has made up her mind..<G>

...I myself have the modem and two phones, both are digital...but I assure you, if I connect them up wrongly ie before the filter, I still get terrible interference.......so' no point in talking...time to start doing. Hope you are successful with your new digital phones. You could of course maybe just BORROW one from a friend and see if they all work together ok.......
best....commoner.

here i go again  right i understand what you are telling me and what mobius 1 explained       my phones are both working fine with filters on both   phones   but i   couldnt understand why  when i  put digital  one on extension it worked without filter but filter was on  the main phone and modem i  dont know a lot but i certainly am learning thanks
