No, you're thinking of a maintenance contract with BT on some ancient PDH kit.
VM's POTS service is delivered via in-cabinet MSANs connecting to a PDH network which then goes to the SDH network.

Indeed not. They'll be edge routers/switches to take traffic onto VM's MetNet.
Must be some VM kit lurking in that exchange somewhere to take hand-off from BT. Should be buried in the OLO hostel with the LLU DSLAMs and other goodies.
EDIT: One actually quite obvious thought is that that exchange was being used by VM for BT Wholesale DataStream services and was a handover point, or there may have been some leased circuits on BT tails going in there which are now decommissioned. Makes sense to take the tail back to the nearest cabled area so that it can then use the existing ducting there rather than a brand new fibre run all the way back to the MetNet POP.

Makes sense. In one exchange (where VM have no presence whatsoever) there's a bit of kit with a Virgin Media sticker on. However it also has a yellow Openreach sticker on to say it's now decommissioned. This sounds like the type of thing you're talking about (decommissioned leased lines).
Near the VM hubsite in the BT exchange there's some very old equipment in the OLO area labelled as NYNEX. presumably how they route POTS calls onto the BT network.

Yeah the ducting probably isn't really old. It says CATV rather than Cable & Wireless (which is what the manholes in front of Virgin's boxes in that area say). So it must have been put in after them, probably in the last 15 years.
