From the look of the BTWholesale Database results, it looks like your PCP is already been installed with a FTTC DSLAM cab linked to it and is active though is now full to capacity. Was this done using the Address or landline checker of the BTWholesale Database as the landline one will be more accurate.
As to FTTC speed then read below:
BT Infinity is just BT Retail's brandname for their Fibre broadband services.
FTTC fibre broadband uses VDSL or VDSL2 signals that travel from the FTTC cabinet to your property via the existing copper (sometimes aluminium) line and can currently achieve upto 80mbps. The further away you are from your FTTC cabinet the slower the fibre FTTC broadband will be.
However VDSL/2 signals used for FTTC broadband connection degrade far quicker in terms of distance than conventional ADSL broadband signal do.
Generally speaking if your landline is over 1500 meters in length from the FTTC cabinet to your property then you may not be able to get BT Infinity as you may not be able to achieve over 15mbps, though maybe able to get BT Retail's sub 15mbps FTTC fibre broadband service called BT Faster Unlimited broadband (FTTC) if your line can cope with the VDSL/2 higher frequencies.
However looking at your distance from the cabinet and what the BT Wholesale database says, you may not be able to get any FTTC fibre broadband service due to your distance from the Dslam FTTC cab.
Here is a graph that shows the ADSL(G.DMT,ADSL2 and ADSL2+) and VDSL/2 (FTTC) signal with distance. Please be aware that all ADSL connections are depend on distance from local exchange, where as FTTC (VDSL/2) connections are depend on distance from your FTTC (DSLAM) cabinet. Though all connection types are also depend on line quality.
This graph is also just a general estimation of what the speed could be achieved and not the actual speed you will receive. Also your line maybe longer than you would think as it may not go the direct way to either the cabinet.
You can try emailing NGA Openreach via email@example.com with your landline number, address and pcp(cabinet) number to see if they have any more information regarding your cabinet and to see if your line/property will be able to get FTTC fibre broadband. It may take a week or so to get a reply.
If your exchange area has been upgraded with fibre broadband under your local Authority/Council/Governments BDUK fibre broadband scheme then you will need to email your local Authority/BDUK scheme for information.
**The Commercial Fibre-Optic Broadband Rollout is being managed and done by Openreach for all communication providers/ISPs. The BDUK fibre broadband schemes are managed by Openreach along with your local authority.BT Retail (a communication provider/ISP) has nothing to do with the rollout of fibre broadband.**
