Ok for the central office <=> PSTN switch association.

May we introduce telecom=connection_node for building where only lines are
terminating without any switch inside ?
telecom=central_office will still stand for building hosting PSTN switch.

In france, infrastructure operator is actually publishing a list of these
nodes, but we can't find a list of PSTN switches. Thus, mapping termination
nodes seems easier than PSTN switches.

It's like "trafo" in power standing for "transformer".
Ok for telecom=*

The question was concerning tags.

Data source may be available (like in Germany, or in France by looking at
building permission for new optical central offices) so we need tags to
handle it.

For example :
Copper lines connection node: telecom=connection_node +
Optical lines connection node: telecom=connection_node +
And so on with different types of local loops.

And when multiple types are inside the same building ?
connection_node=copper;optical ?

Don't agree.

We actually map inside power substations with building=yes +
For a central office we may use building=yes + telecom=central_office

Oops, I've made a mistake : confidentiality would be better than industrial
privacy ;)

It was just to remind to don't use protected data. I know in France or in
Belgium we can find leaked files on websites which can't be inserted in OSM
without the official permission of their owner, as usual.
