Which was really my point. Keeping a lot (and it'll number in the
hundreds for Vector) of UPS's up and running isn't a trivial ask. The
cost would be phenomenal, and every time batteries need to be changed
it's an outage for the CPE that's on the end of it.

Yeah, I think that was kind of what Vector were hoping for. But a lot of
their terminating switches are buried in basement rooms to which only
the building manager has a key. I know that we had quite a few instances
of banging heads on walls trying to get access to put our kit in with
Vector's, because the keys to the appropriate room were hard to locate.
