As one with experience with TDM cards, I highly recommend buying a channel
bank and connecting it to a T1 card. That way, you can get a 2-port T1 card,
a channel bank, and have your T1/TDM environment.

I'm not saying you can't do it another way, but I find that my lines
connected through channel banks are more reliable than those connected
through TDM cards.

YMMV
