Re: Tivo urban legends

["Ian Davidson" <ian@xxxxxxx>]

Hi All

I've now had two ADSL installs one at my house and one at my work. Both
have
had problems dropping out. BT have investigated (one for over a month)
but
not solved any of the problems.

I'm currently looking further into the problems but some things so far
I
have found.

Not only the tivo has the effect mentioned. Normally that effect is down
to
leakage from one of the phone lines to earth, this could be capacitive
coupled. I do not have a TIVO (hopefully one day soon, must resist the
bulk
buys !) but to try to prove it is an earth problem leave the tivo
connected
wait for the ADSL to drop out then unplug the tivo from the mains so that
it
has no earth, does this restore the ADSL ?

Another problem is to do with switching in the .3 to 1 MHz range
causing
interference to the ADSL signal. I've got our spectrum analyser here at
the
moment trying to solve why when one of my x10 controlled lights comes
on,
the ADSL losses sync. I can see the interference on the analyser but I
need
to cure it yet. It would seem that the ADSL lines are more than a little
to
susceptible to other items.

Back to looking at my fault.

Snap same router!

Same here

Same here :)

There has to be a solution to this just not found it yet!

Well looks like I was wrong and it isnt an urban legend ;)

As a matter of interest of those who work and those who don't who is on
USB and who is on ethernet adsl?

Ethernet here

I get exactly the same thing with my ADSL Line, plug the tivo in and
booom adsl drops the connect - an the sky digital box and my laptop
modem work fine on my adsl line.

Ray

there is no logic to this and it seems to indicate a problem with
either
your Tivo cable (are you using the supplied one?) or the set up of your
adsl line. Does an ordinary analogue modem work with the analogue port
on the adsl line?

I use TIVO on the analogue port of my ADSL line. Simply plugging TIVO
in
kills my ADSL connection dead. Physically disconnecting TIVO from the
phone line restores the ADSL connection.

Just splitting this into a seperate thread....

I have never heard of anyone having problems with the tivo on the
analogue port of adsl lines and Tivo actually defaults to v34 operation
(you have to force it to use v90) so you are unlikely to have problems.

A comment was made about Tivo using caller id, I am not certain on this
but I am nearly sure I have had Tivo running on both my BT and NTL
lines. I will reconfigure things on my pabx to check this
tomorrow....and yes tivo does work through a PABX before someone asks.
