| 77616 | 2002-09-11 02:08:00 | Actually Billy, I think it's the other way round. The distributed filters block the HF (which is 50 kHz to 1.1 MHz) from the phone, while the modem connects to the unfiltered line. The filters are low pass, not high pass. A centralised filter operates the same, allowing low frequencies to the phones. There will be nasty harmonics from any HF radiation I would think, and agree about the wiring being a radiator in some cases. I can see a minute amount of TVI when my modem operates, on the nearby TV set. |

| 77617 | 2002-09-11 08:23:00 | Hi God You are right as usual . Once I engaged my brain it was common sense . For ADSL you want your phone line unencumbered to maximise its HF response so allowing phones to damp the line would, in the immortal words of an anonymous sage "not be a good thing" :O Filters, therefore, isolate phones, faxes and tortoise-type modems from the incoming line allowing maximum Jetstream performance . Now, back to the interference, thanks to God the scope of the interference radiating network has increased considerably to include all the telephone wiring . However, does this installation have a dedicated ADSL outlet i . e . a filter tapping off to feed the phone system at the point of entry and a new, single, ADSL-only line to the Jetstream outlet tapping off from the input side of the filter? This is what a Telecom install usually does and is the way my system is wired . If it doesn't have that system in place, every phone and fax will require its own filter or to be fed off a filtered outlet via double adaptors etc . If there isn't a filter (either common or individual) preceding every phone, especially the Panasonic then that might be a reason for the interference . Cheers Billy 8-{) |

| 77618 | 2002-10-09 01:01:00 | I have talked to the guys at dynalink about the filters and this is what they told me. Yes it has become apparent that panasonic phones (cordless) do seem to have a problem with adsl in general. The only way to combat this is to get telecom to install a splitter box. Generally this costs around $80 and will eliminate any use of filters. Other than try another phone. The dynaink filters I feel are the best on the market |
