Hello all,
I have a simple question.
I want to use raspberry pi to create a telephone exchange.
I need to use an ISDN BRI but i only can find PCI or PCI-Express boards.
How can I put a PCI/PCI-E on Raspberry Pi Board?
Or how can I fix that situation using Raspberry pi?
Thanks,
Ricardo Silva
In principle, you could go over USB using a USB to PCI "reverse bridge". BRI is slow, so it should be fine over a USB connection. There are chips that do the USB to PCI function such as the PLX NET 2282 but I don't know if there are boards available that use this or other chips so that you can just plug a couple boards together.
Even if you can find the hardware, getting things to work at the device driver level could be difficult. Good luck! 
The PCIE2RASPI board could solve your issues, it can join a PCIE board (mini or standard) with a CycloneIV GX Fpga to the IO signals of the Raspberry I/O board. Cutting the power pins on the header it can be fitted by a flat cable to a Raspberry host. The Fpga on mini PCIe host an end point that have master target capability, de fact it make the Raspberry able to read or write the PC memory.
