Brian West wrote: Isn't it really 1000 interrupts ? not 8000? Yes, that is correct. Each Zaptel card generates 1000 interrupts per second. For a TDM400 card, there are four B-channels transferred during that interrupt cycle. For a TE110P card, there are 24/30 channels transferred during that cyc

Max TNT's are pretty cheap they'll need to price it accordingly. I'm somewhat concerned that the CPU requirements necessary to put the Digium DS3 card to use will be insane. First of all, if the interrupt model remains the same, it'd need to handle 28*8000 irq/s - 224k ints/sec, which by its

Well, I know that channelization is supposed to be done on that card, but I'm concerned, too. Which also, keep in mind, that should reduce interrupts. It's mentioned also that they are not putting DSP's on the card, which I think is a big mistake. Maybe they'll come out with multiple DSP cards
