ADSL Filters - general query


[link to this post]
 
Chaps,

Sorry if this has been asked before but the search doesn't show up anything obvious.

Back in the old days I bought a few of the modified ADSL faceplates from Clarity so I could basically have an unfiltered extension for my ADSL modem. Over the years I have replaced the filter a few times with one of the spares because my modem would disconnect whenever the phone rang (I don't use the 3rd ring wire internally anywhere so it wasn't this). After replacing the filter it would be OK again for a few more years.

So my question, is it known for ADSL filters to "fail" eventually? This doesn't cause any problems if so as I can just replace them. But what about the filters on the BT side? What happens if/when they fail? if at all.. and assuming they have filters on their side of course.

Thanks smile

IMO you have a line fault that the filtered faceplates are masking for a while, until it destroys them.

Have you tried the Quiet line test, (17070 Option 2), using a corded phone directly into the test socket that the faceplate plugs into?

Capacitors are a known failure point for many simple and not so simple electronic circuits, that and the potential for solder joints to break over time.

Hmm thanks.. never thought of that so will give it a go. What will the quiet line test report?

What about the filters on BT's side? Do these ever get renewed? How does BT/the operator know if one of their filters have failed, or do they rely on a complaint from a customer?

Thanks tongue

Nothing, i.e. silence, if you are lucky. Otherwise any noise should be reported to your landline provider as a voice fault (Do not talk about the BB).
