[asterisk-users] Asterisk with Analogue cards

[Obelix]

After playing with Asterisk on a pure VoIP basis I am ready to start Asterisk
with analogue lines.

I have looked around and everything seems to start with TDM400P with various
options and the very basic X100P.

Is there some guide to the TDM400P and how it all hangs together. All this FXO
and FXS options have me at a loss.

What is the X100p capable of, and how does it relate to the more expensive
versions?
