Well the CES is EOLed.

ACX5048 can be had for around $10k, so not cheap for residential customers
but fine for upstream aggregation.

The CER is fine but of course more expensive.  It'll take a full
Internet table, though, which is handy.

For AE resi deployments, I'd aggregate folks onto cheap 48 port
switches then terminate onto a single pizza box router somewhere "less
deep" in the network.  Distributed, in-field L3 termination doesn't
mean you have to terminate L3 right at the customer-facing port.

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 :-).
