Muffled phone since broadband installation

Since i had broadband installed recently, the BT phone line I'm sure
seems more muffled. (Less top frequencies)

Anyone else have similar experience.

Do you think it's the BT line now, or possibly my splitter(s), short of
trying every one in my 5 socket house?

My suspicion would be one of the splitters (often called microfilters).
They're not expensive, and I don't think it's a bad idea to have a spare
anyway. If it is the line you need to have eliminated the possibility of
faults within your house, but if you get reliable ADSL connection a line
fault is unlikely.

I've known the sort of difference you describe come just from using a
different telephone.

unplug the ADSL modem and try a phone without a filter. There is no
ADSL on the line without the modem. A with/without test will show if
its the filter.

It's sure to be the filter causing a muffled audio. Filters aren't all the
same, but lack of published technical info makes it hard to recommend one
type over another unfortunately. The only hard info I've seen suggests that
filters using Chebychev topology can work better than the usual 2 pole low
pass filter, as it allows a higher audio cut off frequency while still
rejecting the ADSL signal.

I purchased a U.S. Robotics Sureconnect ADSL Microfilter
Mfr part#: USR010920

from www.ebeyer.com @ approx. £6.50 (QuickFind: 35720) and the circuit
looks identical to the ADSL Nation XF-1e picture on the above web page.

Alan that is interesting as we don't supply USR, does the filter have a
USR logo or was it unbranded ?

The bubble packaging was branded USR

The filter itself is not USR branded but carries the identity
2E Interconnection
0000-044-051

The filter PCB carries a variety of identifiers
i) 0000-044-051
ii) G W900
iii) E156176

There circuit appears to be laid out in an identical manner
The component count and component type is identical (one capacitor has a
substituted electrolytic capacitor)

Thanks for that, that makes more sense. 2E Interconnection are based in
the Netherlands and use our filter for one of their filter offerings,
primarily sold as an unbranded filter to be included with
modems/routers. It seems that USR are one of their customers and they
are selling it separately rather than, or as well as, including it with
their routers.
