Faxing and PCI (was Re: [Asterisk-Users] Digium cards,

[Anton Krall]

Hi Steve!

I tried the gain tweaking on the E1 just to check but can you tell me if
that thing I was talking about dropping calls when gains are +2 -2 for
example is the right behavior? 

I think my main problem is latency on the te10p cards. I have a te110p card
and 2 tdm04b and te110p's is missing irqs (frame slips) according to zttest,
zttolol and when trying to check the interrupts, I see Im getting 997 or 990
every 10 secs. Also, zttest shows an average of 99.90 not the needed 99.98
or better.

|Hi Anton,
|
|If you need to tweak gains for FAXing, something is badly 
|wrong. The modems operate over a wide range of signal levels.
