They're pretty useless now except occasionally we can find someone's cabinet number from them. They are waaayyyyy out of date - December 2011.
I suggest you try this site
, middle of the second row - "Fibre Broadband Checker" which uses those plus a lot of other more up-to-date sources, but which don't contain the same level of detail.
Your cabinet number may also be shown by this checker
, which is the one that tells you about your own line.
