| Need Tap Into Telco Line |
|---|
I have access to the tag-block with their pair and mine. How would I
best hear their conversations ?
My first thought is to just temporarily connect my pair to theirs,
observing the polarity, and while leaving mine on-hook, just tap-off
my line into an amplifier, which I can hear while I'm working.
A second refinement, would be to use capacitive coupling to their
pair.
I need to terminate my side with a high impedance, so that the
capacitive coupling can also have a high impedance. So that it
becomes insignificant when I receive or make a call.
If I remove my handset, so that only the audio amplifier terminates my
line, during 'listening in', would it work ?
And then by just connecting my handset and/or modem could I expect to
operate without significant cross-talk to the looters line ?
Thanks for any info/feedback,
