Maybe it's slaved from a neighbouring cabinet.
I think most people are assuming when OR upgrade a cabinet to have FTTC capability, the fibre (and accompanying vDSL equipment) will go all the way to every cabinet.
I wouldn't be surprised, especially on lightly loaded cabinets, to see OR locate the vDSL equipment at another cabinet just down the road.
What you have (certainly the shell, anyway) is a bog standard cab (our cabinet, just round the corner, has looked like yours since it was installed about 10 years ago).
If I've read this properly I think it could be a valid point?
Are you saying 1 FTTC cabinet may serve 2 conventional cabs directly?
or are you saying cab41 may link through another cab (which is FTTC served)?
Although both are technically feasible, not sure if the planners are allowed to use either as a solution. Any planners on this forum?
If it's any use, the FTTC cab CAN be upto a 100m from its copper cab, but preferably within a few metres, as seems to be the norm.
