Because microfilters can fail and the microfilter itself could be causing the problem.

That only helps isolate a fault down to a microfilter if you first establish that there is no problem when you try the test socket without a microfilter.

If you don't have a microfilter then you need to convert the RJ11 to a phone socket - not everyone has one of those sitting around but a lot of people probably have microfilters.

OK, fair enough, but the post in question was suggesting to try 2 filters as though they might be players in the problem.

i said try both because typically isps sends out two. Ian72 has explained perfectly why you microfilter a test socket.

Vdsl cutting out can be one of 5 things

a) intermittent line issues
b) router issues
c) microfilter issues
d) internal cabling issues
e) other applicances issues.

As you know doing a test via the test socket splits the issue mostly to a or b) and c). the easiest way to test further in this instance is to try a second microfilter - hence the double testing.

Sky will replace the router if it is thats what causing it. But Greysurfer would then be able to raise a fault knowning he's done a proper test and safe in no fees being applied to his account.

OK, thanks for this. So expressed in my logic: "You may need a microfilter to connect into the test filter. If this is the case, don't forget to repeat the test with another filter in order to eliminate the microfilter itself as the cause if there is still evidence of the fault"

This never crossed my mind because I threw away my dangly ADSL filters as soon as I got a faceplate filter and I don't think I ever had to use the test socket.

what is a test filter

I certainly didn't. I kept mine unused, i was asked by pn at one stage to test at the master socket test socket with the microfilter in. I had at one stage have a fault, and the OR guy junked my brought vdsl face plate and bunged a new one.

i didn't bat an eyelid - because i knew they were cheap and fail and its better to have a new one.

I don't care about this silly argument; what i do care though, is that graysurfer225 has had a second thread destroyed whilst asking for help and info

Eh? AFAICS, it is a reasonable discussion and relevant to OPs problem.
