Is there, or could there be, a way to synchronise them so that both cards can be serviced by the one interrupt. Or is it more the work that needs to be done per interrupt rather than the number of interrupts that is the problem? Exactly... you're getting it. Doing 1000 things a second is not a lot of things to do for a processor that's clocked at 2,000,000,000 hertz (2 billion somethings per second :-) ). It's more of what has to occur during the interrupt handler that causes problems. The TDM2400P busmasters just about everything (including commands to registers and such) so it doesn't have to spend a lot of time in the interrupt handler waiting for PCI accesses. Your biggest problem that you'll probably worry about is power consumption and heat generation in worst case ringing scenario, as someone else mentioned.

And you should consider how many FXS's you're running. More than one card with all FXS's will require a turbo fan to cool and if they all ring you'll need a decent power supply to handle the power draw.Rob On 1/30/06, Steven Ringwald [EMAIL PROTECTED] wrote: Juan Carlos Castro y Castro wrote: How many TDM2400P cards can I safelly install in one PC?

RE : [Asterisk-Users] How many TDM2400P's will a server take?
A PICMG card equiped with Pentium M CPU permits to reduce dragsticaly the power consumption. As this, you can use more power from your PSU for the interface cards. But, for several TDM2460E/B cards with a heavy traffic charge (many simultaneous rings), I believe that it could be better to use a second separate PSU for the cards. The peak consumption is about 120 W on the 12Vcc branch if all the 24 FXS are ringing together. I think that only an industrial PC can provide a so high power level without risk during years not a small office server. You must also think to add further fans to cool the box AND the FXS modules wich have small heatsinks for the hot components.
