In the UK, that would be called a partial E1. E1 is the generic name for 
BT's ISDN30 product.

If it *is* a partial E1, then the Digium TE110P (that's the 
non-echo-cancelling version) is what you're after. Sangoma make a card 
with similar capabilities, and others (like Eicon) make E1 cards with 
DSPs on board which handle echo cancellation as well as a lot of ISDN 
stack housekeeping.

Intelligent cards are *much* more expensive than dumb ones like the TE110P.

If you have ISDN2e (4 x 2 channel boxes on the wall), then you'll need a 
4 port ISDN2e card. Digium don't make an ISDN2e card.

Sorry, I have no experience of the Digium echo cancellers (yet).

All ISDN30 and ISDN2e cards hadle caller id in the UK. BT (or your 
alternative carrier) will have to enable it.


Anytime anyone asks for advice on a small system, someone wades in with 
"try Asterisk at home".  I wouldn't recommend that myself.
