Yes, granted, still not ideal, but a lot better than the original 
estimates.  :-)

Why would you connect 1000 analogue channels to your PBX?  I'm not following 
where you're going with this line of thought.

Myself, I'd use either a MaxTNT or AS5300 to connect 1000 channels to 
Asterisk, but that's just me.  :-)

Meh; analog is teh suck; I recommend T1 cards and channel banks for that any 
day of th week.  *especially* for FXO.

True; perhaps it's time to dig out some code and see what happens if you 
disable interrupts on Zaptel and use ztdummy with hires timers to poll real 
hardware.  :-)
