Use the adsl address checker to find the edges of the area connected to your cabinet.
Make a more informed guess as to where it's hiding.
No guarantee its in the centre.
I think mine is in the pavenent.
The other thing is to use that database for a list of post codes attached to your cabinet and feed it into geomapping online service.
For mine it gave a blob area but doesn't quite line up with the address checker.
Cabinets coverage overlaps.
The longer they take to deliver the more time you get to eek out more information from what you can obtain.
