Hello newsgroup, 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 telecom stuff. 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 guess?!
Any kind of answer and held is highly appreciated.
Best regards Max
