Just been bought a Beocom 1000 as a gift. Plugged it into a spare phone socket in my house and it keeps making my modem lose broadband connection. Tried it in different sockets and removing other phones, but it keeps on doing it. Any ideas what's wrong??

You probably need to put an ADSL filter between the phone and the socket. When you have a PSTN line and ADSL coming over to your house in a common pair, they use different frequency bands (the phone is baseband as always, and ADSL is configured at the provider end so that it will only use frequencies above that). So in principle they won't bother each other, but the telephones can still "load" the upper frequencies enough to prevent the ADSL connection from working.

Your other phones may have this filter built in, or the Beocom 1000 may be more "hard" this way, being old technology. Anyway, you should be able to get the necessary filter quite cheap - it plugs in the wall socket and has separate outlets for the telephone and the broadband modem. You don't have to have the ADSL modem in the same socket, just connect the Beocom through such a filter. Hopefully it is simple as that!

Thanks Mika

I think I have a spare filter somewhere, so I'll try that in the morning and report back!

If you can't find a spare ADSL filter John, I have a fair few knocking around and I'm only a couple of miles from you...

Chris.

Thanks Chris

I went to the pub tonight but came home and dug around in the garage and found a filter. The Beocom is now working properly and I am mightily relieved, so thanks to Mika for the advice and to Chris for the kind offer :)

What is weird though is the fact that I have had a Trimphone, a BT Genie and a BT 400 series phone all plugged into my house's sockets without filters for nearly two years, but it's the Beocom 1000 that has interfered with my modem after all this time. Very strange, but at least I now know what to do.

Thanks again - this forum is so helpful!

Well done John, I'm not usually that productive when returning from the pub

I suppose new phones may have some filtering already built in, the Beocom just loads the line more, or you happened to try it in a socket that interfered the most with your modem. ADSL can correct some line imperfections, but at the cost of bandwidth if some carrier frequencies have too much noise or attenuation. If you're feeling experimental, you might try disconnecting all phones that currently have no filter and then rebooting your modem - you might be able to coax some more speed out of your broadband.

Hi Mika

You were quite right about the extra broadband speed - I re-booted the router and it was indeed significantly speeded up. Just got one more phone to connect a filter to now....

Thanks for the advice :)
