Yeah it's quite similar to the Italian phone socket too.
Lets just hope they never visit a country that uses BS546 2Amp for its intended purpose and decide to plug in their laptop!
I'm not sure how modems handle 230V 50Hz
Local telephone sockets are rapidly becoming a bit irrelevant anyway these days.
All phones, modems etc use RJ11 sockets these days and quite a lot of the world uses RJ11/12 sockets on the wall.
I notice Apple ships computers with an RJ11 lead and an adaptor for the area they're being shipped to.
Thankfully, Telecom Eireann adopted RJ11/12 outlets back in the 1970s when they decided to introduce modular sockets.
The BT system seems to be a blatent rip-off of it though
It's exactly the same design made slightly bigger, in white plastic and tweeked a bit.
