Can you here the fans in the new cabinet? If not then UK power networks may not have installed power yet (else they have installed power and left switched off ready for BT).
Our cabinet was also one of the last in the deployment and things moved quickly once the cabinet was in place. After the cabinet was installed UK Power Networks came back 2-3 weeks later then OR came back for 2 more days the next week. Immediately after that the cabinet went live and FTTC was available to order (1 month earlier than RFS date). So you may be very close.

It does appear odd and misleading for them to put a "Fibre broadband is here" sticker on the box if it is not!
