Asterisk (and the  rest of softswitches) is free, and cards from Digium (and
some competitors) are quite cheap, expensive is carrier-grade telco switch,
where the smallest card has a 16 x E1 and costs more that 10 x ( DE410P +
HWEC + good quad core 1U server).

TDMoE is your friend.
As far as i remember there is no way to have two separate asterisk on one
psychical TE410P/TE210P, you need two hosts (two PCs) one of them needs to
have a TE410p, another one could use TDMoE or another E100P card or
But this setup will work in 100%.

Better is to check if someone has successfully connected to your-carrier
type switch, so if your carrier has a SS7 switch from vendor X in version of
Y and you want to pass a services like A,B,C, you should ask if someone had
trouble using A,B,C on X in version Y. If it's just simple voice calls with
ISUP version 1, then it will work.
