we are three enthusiasted electronics amateurs and we got that idea into our
heads to build our own splitter box. I have a ISDN+ADSL connection at home.
Based on that connection we would like to separate the
a) DSL signal
b) ISDN signal
c) Analog telephone signal (POTS?)
with an appropriate self-implemented hardware setup.
Does someone have experience with this, which he / she would like to share
with me? Has somebody already implemented such a cicruit or could someone
explain to me how this is achieved best? A block diagram would be surely
helpful, because unfortunately we do not have much notion of the whole
Are there integrated solutions, i.e. special components, which one could
use? I would search for components myself but I don't have a clue under
which keyword those components are traded? It would also be helpful to know
something about the expected signal characteristics, e.g. voltage swing,
offset, frequency range, etc. I can remember something like voltage offset
of -60V at the POTS signal.... or something like that? What about the
ringing impulse with ISDN and POTS? It is definitely different with bioth, I
Any kind of answer and held is highly appreciated.
