I'm a European. Correct. Our ST interface is RJ-45 only. But the U interface can be either RJ-11/RG-59 (4-pin modular) *or* RJ-45 (8-pin modular)-- manufacturers over here can't seem to make up their minds which one they like more, though most TA's and router are equipped with both U and ST interfaces, and many are equipped with POTS ports (Plain Old Telephone System) for analog devices. The U interface is right off the switch--no termination or anything, and requires an integrated NT-1 to use. The ST (SO) interface and POTS ports are (essentially) just like European version. R.
