I am speculating here, Scott, and perhaps Frank, who runs the boxes, will
chime in, but my understanding of the Calix E series is that you can separate
the *traffic* on a per port basis, even on the GPON cards, as to where
that traffic is routed to, presumably by VLAN.
I don't think, on rereading your post, that that's what you actually mean,
though; I think you're asking about something which I myself
got to yesterday afternoon:
Can you separate the *control plan* on an ISP by ISP basis: is it
possible to give ISPs whose clients are on specific ports of an access
mux like an OLT *control over only those ports*, leaving card- and chassis-
global functions for the L2 operator? (Possibly with the optimization
of allowing card-global functions if all the ports on the card are owned
by that operator, or unassigned.)
It's a very good question, and the next nail I was going to hammer.
I'm betting the answer is presently "no; you'll have to put a smart
OAM&P layer in front of it", myself.
Can anyone who's used such Access multiplexers comment on this?
Cheers,
