VDSL on waiting list, but G.fast available?

I'm not totally sure how it works, but can I order G.fast even when there's no space in the cab for a standard VDSL connection?

Would my line connect to the G.fast equipment instead of the VDSL equipment?

I might be wrong but as far as I am aware G.FAST is via a pod that get connected to the PCP Cabinet, VDSL (i.e. FTTC) is via a fibre cabinet.

I am sure somebody will correct me if I am incorrect.

Yes, you can order G.Fast if it shows as available, even if FTTC shows a waiting list.
They have their own independent ordering systems.

They are completely independent of each other, in every way.
The same way that ADSL availability has no effect on VDSL2 availability.

They are linked via power supply only.

Yes you can order it.

As the others have said, two separate services from two separate bits of kit.

I see, that's good. Thanks everyone.

Virgin Media are coming here as well (cab recently installed), so I'm spoilt for choice, but I'll be moving in the not-so-distant future, so the 18-month contract is too much.

G.fast is bit too expensive atm imo. I don't personally need those speeds.

Out of interest, what kind of capacity does G.Fast have, both amount of users per POD and fibre back-haul to the main exchange?
And once G.Fast gets ordered by people i expect over time a few VDSL ports would become available again?

A small Huawei cabinet (Huawei MA5616T DSLAM) has up to 128 ports. That increases to 192 ports with a High Density expansion.

A large Huawei cabinet (Huawei MA5603T DSLAM) has up to 288 ports. That increases to 384 ports with a High Density expansion.

An ECI cabinet (ECI M41 DSLAM) has up to 256 ports. They can't be fitted with High Density expansions.

An AIO (All In One) Huawei cabinet has 128 ports. They also can't be expanded.

I'm not sure on the capacity of the current G.Fast line cards. They were aiming for 48 ports per pod I believe. That might even be 48 ports per line card, with 2 line cards per pod.
The current generation of G.Fast line cards are likely smaller than what they will eventually be.
I'm not sure to be honest, somebody will come along and correct that no doubt.

G.fast 48 line card ports with future 96 port once software is reliable for vectoring 96 lines. Space for the extra 48 ports is already present.

Fibre one of the spare fibres from the VDSL2 cabinet is linked across to the pod.

Does the G.Fast pod run off the battery backup from the VDSL Cabinet?
and is the backhaul to the cabinets direct fibre and not like GPON fibre?

The pods are powered by a 48v DC supply derived from the PSU in the donor DSLAM cabinet. Backup supply is also from the batteries in the donor cabinet also.
Fibre is direct via the aggregation node.
