[Asterisk-Users] TDM400 FXO vs FXS Interrupt performance

[Dustin Goodwin]

I have read a lot online about interrupt related cracking/popping noise 
issues on Digium cards. The weird thing is I experience it with the FXO 
port on my TDM card but not on the FXS. Does this make any sense? I had 
assumed an interrupt problem. But if the FXS port is working why would 
the FXO port be having a problem?
