> 1. D/120JCT-LS card with 12 ports. This ports are FXS ports?
Depends from which side you're looking? From the telco side, yes - The
D/120JCT-LS card is like 12 regular telephones. You plug 12 loop start phone
lines in to this card and it provides termination.

Yup. That's why we like cards from Digium - they're cheaper and better
supported.

The card provides analogue line interfaces - I'm not sure what configuration
you're trying to achieve?

I've used similar Dialogic cards to provide IVR services under Windows but
not Linux. You need some software to make the cards do stuff - you can write
your own or use a scripting language or appgen. Check out CT-ADE from Intel
(previously known as VOS from Parity Software).

You could use a TE410P card, have your E1 terminate on one port, then have
one or more channel banks connected to the other ports to provide FXS ports.
It's probably cheaper to find T1 channel banks, so you'd need a couple
of
you needed 30 FXS.
