You seem to have had your RJ question well stomped on. Suffice it to say that the connector and pinout for the S/T interface is the same in the US as in Europe. I believe that the electrical interface is the same as well.
Now to address the protocol question. I believe that you could get your product approved in the US and Canada using the CTR 3 protocols, since the requirements here for approval are very minimal. However you won't find any publicly available lines which use this protocol. The US took a different track in setting the intreface standards and you will need to research these. I would suggest that you look at the Bellcore, now Telecordia or some such, standards NISDN 1 and, maybe NISDN 2 to find out what's required. There are probably ANSI standards as well which cover this.
