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.
