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?
