Second FTTC Cabinets

So it looks like 2 of the 3 (including the one I'm connected to) local NGA Cabinets are full and Openreach are adding a second cab to each to increase capacity.

I was wondering if anyone can shed any light on what these duct markings might mean?

EDIT: I should also note the behaviour of the BT checker in this scenario.

For Cab 1, checking any number shows available (must be very nearly full in that case)

For Cab 7, checking a non-FTTC number shows no FTTC of any kind, nor Fibre Multicast.

For Cab 7, checking a known FTTC-enabled number shows FTTC as available as normal.

Is one of those a half height cab?

The postcode / address check appears to be a bit hit-or-miss in some areas.

Not yet seen any second cab here but we have full height ECI and Huawei cabs.

Both of the current NGA Cabs are Huawei 128 line, and I would take a guess that the new ones will also be Huawei 128?

I used the telephone number checker, not the address/postcode checker to rule out any postcode related strangeness. From that my only conclusion is that the checker knows which lines are FTTC-enabled and shows them as such on the checker?

D54 is 'Duct 54' - which is a 96mm diameter tube.
'450 cover' is the depth required and the arrow marks the position where it is to be installed to enter the joint box.

You stated cab 7 twice. I presume you meant 1,7 and 12

No I meant 7 both times, I was checking a number that has FTTC versus a number that doesn't have FTTC and noting that the checker can tell the difference

Thanks!

Half-height cabs? Since when, and where?

How will vectoring work where there are two FTTC cabs serving a single PCP?

multi-vendor and multi-DSLAM vectoring is in the standards development mix I believe.
