Actually, the US ISDN devices I've seen use the same RJ45 connector for the U interface that European ISDN device use for the S0 interface. All of this of course just adds to the confusion, as the connector doesn't tell you whether or not the NT1 is integrated or not. The US equipment I've seen does label the connector "U", so looking at that might help. I seem to recall that US ISDN devices call the S0 interface "S/T", but don't take my word for it. I'm a European.
