Dear everybody

I'm confused about the different use of ISDN connectore in EU and US.

Our situation is:

     we make a Bri ISDN (TRB 3) interface which uses a RJ45 connection

     we want this interface approved by FCC part 68, BUT will use EU ISDN lay
1-3

But as I can see RJ48 connection is used in the US which differe from RJ45 in
the wiring of the modular jack connector.

My questions are:

     is RJ45 used in the US/Canada at all ?

     can we have a FCC approval of a EU ISDN ?
