[Asterisk-Users] TDM over PCI bus - Electronic payment terminal

[Olivier Krief]

Hello,

Does anyone have successfully connected an electronic payment terminal to an 
ISDN BRI Asterisk server ?
Here is the architecture :

Public ISDN ----- [Junghanns.NET QuadBRI card inside Asterisk server ----  
PCI bus ---- Digium TDM2400 inside Asterisk server] ---- Electronic payment 
terminal

Would you trust TDM compliance of such a system or would you move to 
Ethernet electronic payment terminal such as
