Hi,

Thank you for your feedbacks.

Ok.

I think it's important to distinguish places/buildings from services
(DSL,POTS...) they host and kind of local loops connected to (copper,
fibre, coax).

Even if FCC wants to shut down legacy switches in favor of IP, the building
will still be called a "central office" according to what a central office
is but services provided may change or local loops enhanced.

That's actually very nice !

In my mind, MDF is only a functional part of a central office (like
switches, DSLAM, power supplies). *We shouldn't summarize the building
itself to a part inside it*, should you ?

Ok for me, but let's be careful with security and industrial privacy, as
usual in OSM.

Before starting using it at a large scale : should we use telecom=* or
telecom*S*=* ?

Then, it seems we can still use "central_office" for such buildings, but :
- Should we add services it provides ? (DSL,Cable TV,telephone...)
- How would we distinguish a copper central office from optical or coax
ones ? Be careful, a copper one can be an optic one or coax one too.


Cheers.
