    If I'm using a TDM400 with an FXO and an FXS card,
    if my inbound route is sending the call arriving on the FXO POTS to an analog extension on the FXS is there any conversion in between or is the signal converted to digital then to analog again?

    I was thinking about keeping an analog fax on the fxs. Will I loose quality/reliability with this setup instead of connecting the fax directly to the POTS line?

    The analog signal is digitised by the TDM400 (to slin I believe) either way, negligible degradation, and the chance to rebalance RX/TX gains on the way through.

    do your fxotune -i properly and probably things get better not worse!

    Thanks Dicko,
    sometimes I'm asking myself some questions that make me rediscover again the basics... ;-)
