<p>So it might make sense to have some other external process that offers this "one FD per timeslot" notion to libosmo-abis. This process would then be talking to the USB device (or exchainging UDP frames) with the E1 LIU, and do the timeslot de-mux + HDLC processing.</p>
</blockquote>
<p>actually, this is rather important. Only if we have individual, per-timeslot interfaces (such as fd/sockets), we can have OsmoBSC attach to the signaling timeslots but OsmoMGW attach to the traffic timeslots. So this is one important argument in favor of having an external process/damon handling E1.</p>
<p>The overall picture then looks like this:</p>
