I think it must be about the only one.
The only place that I come across OSI protocols in actual use these days is in management of legacy telephony equipment, and those management systems are being replaced with IP based access.

Had to be asked! Sorry if you throttled youself... :-)
The military are heavily into X.400 in some countries, as they make use of many features missing from RFC821/RF822 et al. LDAP Directories are based on X.500, minus the ISO protocol stack. ASN.1 was originally part of X.400, but moved out in its own right as it became clear lots of other things including some Internet protocols were going to use it (although I never understood why SMNP uses ASN.1 rather than XDR).
But you're right, in most places it's dead, or the overweight protocol stack is at least stripped off and it's run over IP.
Fair points. I was mainly thinking about transports, I suppose.
I've used miniature mains connectors in the past, but they're a PITA, so I bit the bullet and went back to full sized ones everywhere.
In the UK we have for many years classified them sufficiently well to be able to say that. Finding what starts a fire in a domestic setting isn't usually too difficult.
60 odd years, and in the early days the proportion of high current appliances on a ring was much larger as 2kW radiant electric fires were common as few houses had central heating.
What on earth has heating habits in Sweden got to do with the UK ring main?
Empirically I think it's true. I've never seen a scorched Italian plug or socket, scorch marks on 13A plugs are common and also on 13A sockets, particularly for 3kW heaters and kettles. The fuses in 13A plugs are prone to overheating and they offer piss poor protection, particularly since most of them are 13A even when fitted to an appliance in need of a
3A fuse. The appliance should be fused correctly, fuses in plugs are a stupid idea.For some bizarre reason British consumers don't seem to regard the fishy amine smell of an overheating electrical fitting as a sign of danger.
This time, of course, the lessons about sharing the control channel with the main transport channel will have been well-learned and understood; the ready availability of authentication technologies will avoid the 'blue-boxing' problems that led SS7 to be so quickly welcomed by the telco operators.
(Meanwhile, back on planet reality... !)
ATM has some OSI-flavoured legacy in it, of course. But it's notably failed to be the desktop-to-desktop or desktop-to-server IP-replacement that it was touted as - it's just another link protocol to carry IP.

That's in the EU now?
So to "encourage" the rest of Europe we have to spend billions changing from a perfectly good system to one which, at best, is no improvement?
It has? Possibly in communications but certainly not elsewhere.
I think you will find they still are. On one standards committee I had some dealing with a retiring French delegate used the last meeting to introduce his son who was taking over the "family place".
You were doing quite well up to here.
Which I suppose explains why I have several Bluetooth devices none of which will communicate adequately with each other. The nice thing about standards is that there are so many of them to chose from.
Err....???? How do they do that?
So when will that happen with Bluetooth?
In my experience you are almost correct, we've successfully exported our
*components* around the world, but necessarily wiring practice.I've been presented by all manner of randomly wired bird's nests in the Middle East, but at least they're terminated in nice shiny MK BS1363 sockets.
I work for a bank - and it's still stuffed full of it!!!
The IEE say it can't.
I think we all know a ring would be safer if the cable and breaker *were* the correct size.
If it were down to cost then everything would be wired in thick cable so you didn't need to have any skilled installers. The cost of materials is insignificant compared to the labour costs.
The "strings" camp has moved on to MPLS now :-)
Well if you want to go from first principles then why not.
Suppose you have a cable resistance of 1ohm @ 20C
Then when you heat it to say 100C the resistance will be 2ohms
This means that it is dissapating twice the power it was.
So now we are dissapating twice the power does that mean we have reached equilibrium or is the tempreture still rising.
If its in an insulated wall it *will still rise*.......
It sounds like once you start heating a cable it will just get worse.
Contributions as to why it would/wouldn't are welcome.
But no one could afford to run them so you wouldn't get 5 or 6 turned on.
I took my own 1363 stuff to cebit for the last show I was at. The German ones are just a bit hot.
The electricians there say that all is fine if you can hold the cable without getting burnt.
You use a portable air conditioner in a kitchen?
Well, they just don't work properly. Get a fixed one, and feed it off a dedicated radial circuit.
And you dry your hair in the kitchen while frying the chips? Doesn't it smell afterwards?
Almost all UK voice traffic - fixed and mobile passes through switches using such protocols end to end. The BT IP based initiative will replace this in due course but that's some way off still.
Because one day not so far in the future the gas runs out. Start planning for it.
