thanks to everyone for all the replies.

I have a doubt about how to connect the NTBA, since it
has a U interface and an S0 interface with two sockets. Would I connect
the Billion card to one of the S0 sockets on the NTBA (via a crossover
cable) and then the telephone to the other S0 socket. I assume that I
don't connect anything to the U interface of the NTBA. Is that correct?

Thanks,
John
