One of the reasons I'd pay a little extra for an Active-E FTTH-centric
switch is to control bandwidth right at the port the customer connects
to. Cheap Ethernet switches generally don't have this capability (or if
they do, have it in only one direction). This is why I felt the CES/CER
were reasonable, but purely as Layer 2 termination and not using their
IP/MPLS capabilities.

Anyway, it's been a while since I had any interest in this, so it's
possible life has changed since I was at the beach :-).
