I actually meant Its at the exchange
It doesn't mean that either. Every Openreach Head-End exchange has FTTP to some extent.
FTTPoD availability used to be limited to lines connected to an FTTC enabled PCP.
They excluded lines on cabinets with no FTTC and exchange only lines.
MDU's have always been excluded.
FTTPoD coverage was expanded (considerably) with the FTTC cabinet requirement removed. MDU's remain excluded.
There are still areas with FTTP available at the Head-End exchange with no FTTPoD availability.
Frankly I have no idea what the availability criteria is. I don't know anyone else who can pin point it either.
Openreach were extremely vague when they announced the coverage expansion.
I do know it has nothing to do with FTTP being at the exchange though.
