Germany had an import from all "Deutsche Telekom" COs  

Example http://www.openstreetmap.org/browse/node/307194821

Its a man_made=MDF (Main Distribution Frame) - ONKZ is the area code
which is variable length in Germany and we have approx. ~6000 of them.

A CO/MDF in Germany will be identified through their Area-Code ONKZ
and the ASB (Anschlussbereich) which is a segment of that area code.

But i'd favour a group of "telecomunication" based tags. There is more
to be mapped e.g. what we call Kabelverzweiger (Kvz)


or the German "Oberirdische Linie" e.g. poles for telecommunication
cables. Most cables in Germany are in the ground except in the "Outback"
where we have utility poles. But typically we dont have utility pole
sharing between telecommunication and power.
