<div dir="ltr">Pardon my ignorance, but if you were to progress from FTTdp to FTTP, I would have expected there to no longer be a need for power in the pit anymore (once all FTTdp was upgraded).

</span>From FTTdp to FTTP. Say, 10 years after we're all spun up with FTTdp.<br>

<br>
</span>Yup. That was rather the point of my post. How that might be solved as<br>
part of moving to fibre all the way.<br>
<span class=""><br>
> * That's the point of my comment - the power for the 'pit'/FTTdp equipment in the pit comes from the attached subscribers' CPE (and therefore the subscribers' mains supply.) The FTTdp equipment in the pit doesn't need an independent power source. In other words, if there are no active CPE attached to the FTTdp equipment in the pit, it isn't operating.<br>

<br>
</span>Yes I know. But in a post-FTTdp world when you spin up new fibre to<br>
the premise you might include something that solves the power problem.<br>

<br>
</span>That's not what the bandwidth numbers say.<br>
