I'm confused as to why the engineer needed to do anything on the original pole. Was this a telephone install, too?
As for cabinet 10, it may be upgraded in the future when OpenReach do infill.
What does this
say for your number (assuming a BT line)?
You could email the NGA team at firstname.lastname@example.org
and ask about cab 10 (might take a while to get an answer, though).
