[Asterisk-Users] How many TDM22P Card can be used on the same PC ?

[kalezade at boun.edu.tr]

 Is it possible to use 24 FXS/FXO lines(on 6 PCI slots) at the same time on the
same PC? 

I wonder for sound quality and power issues. Can anyone convince me that I
can(not) use 6 TDM22P cards?

Thanks in advance.
BDM.
