Also means either further work to do in a few years, or committing to keeping the street furniture with largely redundant DSLAM once VDSL2 is dead
Andrew I�m pretty sure they don�t actually mean they�re jointing spare fibres inside the VDSL cabinet itself and then back out to an FTTP node. It�ll be done in the jointbox in the pavement in front of the cab. They just mean spares in the fibre cable that was put in to service the VDSL cabinet.
My understanding was neither.
A mini-OLT would be installed inside the FTTC cabinet. Specifically the Huawei MA5800-X2.
Spare fibres can be be used but the whole point of it is it extends the GPON signal further to reach properties too far to receive GPON from the Head-End OLT.
It would only borrow a power supply from the FTTC DSLAM.
No other connections to the DSLAM would be necessary.
It could go underground but it still needs a power supply.
