Re: Further to my ADSL Faceplate Question

["Tracey Gardner" <tracey.gardner@xxxxxxxxxxxx>]

Hello Simon

Many thanks for your reply and the Wiki reference.
I do have mains power where the telephone line comes in, as it comes into
what is best described as a service cupboard, where the mains supply also
comes in.
It looks as though I'll have a to do a little experimentation.
One port routers are cheap enough to play around with and I'd feel happier
forwarding the broadband to Node 0 via a balanced CAT5 cable as opposed to
an unbalanced unfiltered ADSL signal.
There is a distance of about 25m between the service cupboard and my Node 0
so I imagine that the unfiltered ADSL signal would radiate quite nicely
from
that as an aerial.

Regards

Tracey

I hadn't thought of that before - a quick Google wasn't very instructive,
though does show the ADSL frequencies as:
http://en.wikipedia.org/wiki/Asymmetric_Digital_Subscriber_Line
With standard ADSL (annex A), the band from 26.000 kHz to 137.825 kHz is
used for upstream communication, while 138 kHz â?? 1104 kHz is used
for
downstream communication.

whereas CAT5E/5 runs at 100/250MHz I think which is quite a lot higher up
the spectrum.

Just in case you don't have mains where the ADSL master socket it I wonder
if there's any benefit in using a screened cable for the ADSL signal to
node
0? Also it is nice having everything together for testing and, because many
ADSL routers are multi-function, may be more energy efficient.

Just a thought,


Simon
