Those postcodes aren't where a cabinet will be placed, but postcodes that will be served by a cabinet.
The cabinet can be a up to a couple km away and still provide service.
They often put All In One FTTC cabinets for EO lines right outside the exchange building.
I get that info from the OpenReach website.
Enter those postcodes and pick a couple addresses, it shows they are in plans to get FTTC.
I only checked a handful of postcodes on the exchange.
Edit: PH7 3RT is indeed another exchange I'm wrong on that 1
You can see the postcodes of the EO bundles
