        We look forward to map places, not devices for now.

        People used to put man_made=telephone_exchange or man_made=MDF
        to tag a building/place while it's only particular devices inside.


    Thanks for that, but I'm afraid that the continual OSM worldwide
    translation problem is raising it's ugly head yet again.

    In Australia at least, "telephone exchange" refers to the building
    itself, which houses the Main Frame (where all the cables are
    terminated) & the various types of switching equipment. In 20
    years of working for our Telecom, I never heard the phrase
    "Central Office" - the closest thing that would refer to is an
    Admin Office of some sort.


+1, most of the time that building would have a name like "... Exchange" and tagged currently as simply man_made=telephone_exchange. This makes it easy to survey from the outside without working in the industry to know exactly what's going on inside the building.

Central office is confusing to me as it sounds like it's the head office of the company, ie. office=telecommunication.

I know these terms are different by country and we need a global tag, but just letting you know the proposed usage would be very confusing for Australia.


It may also be confusing in Britain.

In 1976 the last manual telephone exchange in the United Kingdom at Portree in the Isle of Skye closed.
