Hi all,<br><br>I'm confused, in digium website, it says: <br><h2>TDM2400P: It supports a combination of up to 6 FXS and/or FXO modules for a total of 24 lines.</h2><br>6 plus 6 is 12, how come it's 24?<br><br>if I have 24 PSTN lines, i'll be needing 24 FXOs.
<br><br>Pls. elaborate.<br><br>thanks.<br><br>Lito<br><br>
