how can I cause static or interference on a phone line?

[seattle dave]

I want to cause static or interference on a line that leads from
the wall to a callmaster IV made by Lucent. These are phones used in
call-centers... The line has eight wires and I think it is the same as
a computer data line?? There is no other power source to the Lucent
callmaster, so one of the wires must carry power. The wires are all
small however... It is the same cord as is attached to a computer modem
to a computer....

thanks for any help on this...

would a strong radio signal interfer??

I want to cause static or interference

Static interference is caused by electrical storms.

If the lines are colored blue, orange, brown, and green, with striped
versions, and they are twisted in pairs, then they are probably CAT-5
or CAT-7 ethernet wires, probably running in Power over Ethernet mode.
Incidentally, one of the reasons that the wires are twisted is to
counteract the very interference you are trying to create.

When you are talking about noise in the line, it is very important to
specify the power spectral density (PSD) of the noise, which is just a
fancy way of saying what are the frequency bands where you want the
noise to be created and how much power at a given frequency want. This
implies that you should first figure out if it is indeed and ethernet
cable, and if so, what is it for. If it is an Ethernet signal, then
you should check to see if it is using 10mb/s or 100mb/s. Once you
have done that, there are tricks that you can do to cause the right
type of interference, but keep in mind that waves on Ethernet are
sqaure, not smooth like a single sine wave. This means that an
Ethernet "radio" would have to be tuned to all the different radio
channels at once to hear Ethernet "music" at the other end if it were
based on FM. Therefore, don't expect a walkie talkie to do anything.
If you kill the frequency in the Ethernet wave at the walkie talkie
frequency, it won't matter, because all the other sine waves embbeded
in the sqaure wave will work together to "cover the back" of the sine
wave you disturbed. But there is something that might work. Simply
find the cables that are used for data (look up ethernet diagrams on
Google), and cut into them (be careful), and put some long UNCONNECTED
wires dangling off the ends. The signal will see the dangling wires,
run down them, hit the end and find out there is no were else to go,
then come racing back to interfere with the other signals that are on
the base wires.

Ignoring for the moment there can be no good reason for what you want to do,
the callmaster uses a digital communications protocol which means it will be
difficult to generate enough coupling to the wires to interfere with the
system. The channels are multiplexed to one pair of wires, thus if you do
succeed, it will affect all the channels at once.

This may involve you with certain members of the government who have definite
ideas about interfering with lawful communications. Knowing this, most people
here would recommend you should find another outlet for your energy.

No, a strong radio signal is unlikely to have any effect.

it depends exactly what access you have, and whether you want the fault
to be recognisable as deliberate, but more importantly on what lawful
reason you have for doing this.
