DECT & ADSL
Posted by Sam Salt on September 25th, 2005


My residential analogue cordless phone is on the way out and I was thinking
of replacing it with a DECT phone.

Are there any compatibility issues with Broadband/ADSL or is it just a
simple replacement

MY ISP is BT Yahoo Broadband if that is a factor in anything.

Thanks,


Sam Salt

No problems here, have a two phone set and no interference experienced.

No problems here with a BT Freestyle 2500 dual-phone setup, but search this
group in the Google search page ... ISTR this topic has come up before about
2 years or so ago:

The main watch-it is to make sure that you have decent quality filters,
especially if you intend to use Caller Line ID. Cheap filters generally stop
this working properly. FYI, I use the following:-

Why should there be..? A DECT phone is no different to any other as far as
the phone line is concerned.

Do you have a DECT phone and CLID on your line? Those cheap filters normally
prevent such equipment from working properly.

Except it and ADSL use radio frequencies !. I accept they are a long way
apart, but I did have trouble with ADSL buzz on my BT DECT and solved it
with a better filter, one which had 4 inductors instead of just two.

Why not wait for BT (con)Fusion?

It's called business sense, if they can make more money on an item
than the next guy then fair play to them. This isn't about the Dixons
pricing structure though and the above example bears no relation to
the original points you raised.

its "just a phone" with an RF transmitter in it that could interfere
with the ADSL or vice versa if not properly filtered. Any phone can be
a nuisance in this regard if the filtering is inadequate, and there is
a correlation of poor performance and cheap filters esp with DECT
phones which can be gleaned from places like this.

the "I'm alright jack" recommendation is of limited value if you are
sat with a high level ADSL signal and phones not disposed to be a
nuisance, whereas someone with a very weak signal and an ill-behaved
phone may not enjoy your success.

The early problems were caused by 'leaky' filters & the preamp on the
telephones being particualarly wideband, this could be cured by either
double filtering the phones or using an plugin RF filters between the
ADSL filter and the phone. There were types of phones (especially
cordless) which were incompatable due to this problem but in the more
modern phones they have apparently cured it.

The only time I meet up with this problem nowadays it is normally caused
by an H(igh) R(esistant) connection on one of the 'legs' of the circuit,
sometimes easier to find than others.

I didn't tell the OP he would definitely need a certain filter. I said he
should make sure he has decent ones with DECT and particularly if he intends
to use CLID. I then went on to say which filter I use. He may not have any
problems with his existing filters, however he may and at least now has one
recommendation. You should perhaps try searching the archives of this NG
since this issue has been raised countless times and the ADSLNation filters
have been recommended many times, because the cheap 99p filters are not
always up to the job.

I have four DECT phones and a BT Voyager wireless router. I am using
the filters that came with the router - don't know if they are 99p jobs
or "expensive" ones. I hadn't really given the filters much thought,
but I /was/ concerned that the RF signal from the phones might
interfere with the RF signal from the router, or vice versa. However,
no such problem has occurred so I guess I needn't have worried. Two of
the computers on my network are also Bluetooth enabled, but that
doesn't interfere either.

On the other hand, I don't have an ADSL signal. BT have acknowledged
that there is a "fault" on the line (nothing more specific) and are
coming round to investigate on Thursday. But I'm beginning to wonder if
the problem might lie with the filters after all.

So, would it be worth my while trying different [better/more expensive]
filters?

unplugging everything to see if the ADSL works would give you a clue,
then add things back until it falls over and you'll see what's causing
the problem.

When I had a fault on the line, BT were able to tell me the fault lay
outside of the house and not my own equipment. You could ask them to test
for that.
