Steven,
  If we grant that you are correct and that Digium and friends are
making hobbyist products..... Then what are the "serious" installs
using?  We're serious to the tune of 5 FXO ports and 3 FXS ports and I
want to make sure we don't waste time on flaky hardware.  I figured that
as Digium built the hardware and wrote the original code they probably
know it better then anyone else.  You just seem to know a lot about the
serious installs so I'm curious what you use and how many lines you run
with it.

Btw, we are a textbook "small office" install according to the docs.

Also what the heck is FC?

And we come full circle to a comment I made before that TDM cards are
more for hobbyist than for real serious installs. A real install is
probably going to use a T1/E1 interface and bypasses all the troubles
listed in this thread.

So far I don't trust that many of the people using TDM cards are the
ones who will tweak a system into a serious install. Look at previous
threads about system load spikes where we have to pull teeth to get
people to swap out of a FC kernel and into a generic kernel.
