Samknows gives dates for the exchange go-live for FTTC, not individual cabinets.
The only guide is the BT Wholesale ADSL checker. If you input your telephone number to that it should tell you a ready date for your Cab (or not - it quite often seems not to know!).
Has the electrical supply been fitted and the FTTC Cab connected to the existing one? It can be many, many months fronm the Cab being installed to it going live.
