We can find the two possibilities and I don't write that all telecom
cabinets are actual telephone exchanges.
Such a cabinet :
hosts DSLAM, switches and WDM and is definitely an actual telephone
exchange in a street cabinet.
It's sometimes directly written on them: In France, NRA = Noeud de
Raccordement Abonnés = Subscribers connection node = Telephone exchange.

Whereas this :
is a more simpler outdoor dslam *linked* to an actual and remote telephone
Then it's not a telecom exchange but a local loop component (distribution
hub, why not)

That's not my point nor my intention: I introduce telecom=service_device
for standalone dslams which are not in a proper telephone exchange.
Tagging proposal are here to provide consistent terminology to cover as
many cases as we can encounter on field.
Finding telecom networks data may be hard and this proposal is followed by
long term work to encourage telecom operators to open their network
Open data will be required to complete the map.
All the best
