Is T100P 3.3v or 5v


I have installed a T100P board on a DELL PE 2650.

Linux sees the board as:

Network controller: Tiger Jet Network Inc. Tiger3XX Modem/ISDN interface

I’m guessing that the Digium T100P… Asterisk does not see the board… I have installed the same board on another machine and it gets detected just fine by Asterisk

the only difference between the two servers is the PCI slots…

Does T100P works on 3.3V PCI? PE2650 has 64 bit PCI-X…could this be the reason?

please help…


I think they are all 3.3V. However the third party one I tried wouldn’t work because it required a too recent PCI standard for my rather old home machine.
