Changing Interrupt Frequency in E1/T1 card

Hi,

I saw the feature list of PRI card that there is option to change the interrupt frequency, where can i change that?

hi,
You are able to adjust time to initiate IRQ by the following way.
modprobe wct4xxp ms_per_irq=2 (wct4xxp is the card driver you want to load)
ms_per_irq=2 means every 2 millisecond initiate once IRQ.The valid values of ms_per_irq are one of 1,2,4,8,16, and the default value is 1.

Is it possible to change interrupt pin and interrupt number for BRI card also?
Regards.

Hi,
I have one more doubt lets say I am changing the Interrupt number and Interrupt pin, in lspci it is showing the changes, after I do dahdi restart, only the Interrupt pin changed to the value what i changed but the interrupt number it is showing some dynamic number. Is that normal? please advice.

Yes, it is normal. The interrupt is dynamic, if not, it will not work fine.
BTW, the BRI card is not supportable for changing interrupt pin and frequency.
