[Asterisk-Users] Qs about FXO/FXS cards

[Victor Rini]

This has been an interesting discussion. I'll chime in with my 
experience here.

I have two servers. One with the cheapest motherboard and athlon 
processor I could find on Newegg.com. The other is a 1999 era 
motherboard with a Via C3 processor, again a bargain basement special.
The Athlon system has a decent power supply - 400+ watt, the Via has a 
very generic PS that came with the case - 300 watt tops.

On both system I have TDM cards, the Athlon has a 4 port FXS and two 
x100p's, the Via has a 2 port FXS.

Both systems are in "production" if you could call it that because they 
handle little traffic - home/hobby systems.

I have had no problems at all with the tdm cards or Asterisk. I 
occassionally lose my network on the Athlon machine - I chalk that up to 
the fact that I'm currently sharing an IRQ with two ethernet cards and 
an X100P.

I'm thinking of ditching the two x100p's in my Athlon machine for a TDM 
card with FXO modules to free up a slot and hopefully the burdened IRQ. 
Based on what I'm reading here I probably should think *really hard* 
about that.
