Re: VLAN routing help needed (USG50) said by Kirby Smith:FIOS uses ATM cells for data and different optical wavelengths to discriminate voice from Internet from TV. If they use VLAN tags in any way, they add them upstream from my router.
I assume FiOS is PON based, question is which type of PON. GPON or GEPON. But since you mention ATM cells, it must be GPON, since GEPON does not support ATM.
They can add the VLAN tags on the ONT, this offloads some CPU cycles for the OLT. And usually you would design the networks to use VLAN from the ONT, at least that is what I do

802.1p is not really needed for IPTV, but IPTV benefits from QoS which is what 802.1p is used for.

My FiOS/FAST uses PPPoE over BPON. I think the GPON spec subsumes BPON, but I don't think GPON was defined when Verizon initially architected FiOS.

| Your correct GPON came after BPON. And you might say it extends it. I never read BPON and compared it closely with GPON, so not 100% sure about the details.
