Our incumbent telco has sold the land of 1 of the major exchanges back to the government for the expansion of a children's hospital.

They are replacing the entire footprint of the exchange with fibre.

They install NTU's with 2 POTS ports and 1 ethernet port (i think the ethernet can double as PRI).
They install multiple of these if you want more then 2 lines.

Then the government is building a national network primarily fibre (gpon fibre to the premesis) with some fixed wireless and satellite for the remote/rural area's. With a similar NTU.
