Single- ONTs add S-VLAN tags to iTV service
tagged packets.
VLAN
The OLT transparently transmits packets with
S-VLANs.
Double- All ONTs add the same C-VLAN tag to
tagged packets.

The OLT implements VLAN translation: C->S
+C'.
Single- ONTs transparently transmit upstream packets
tagged with M-VLANs sent from HGW. Multicast
VLAN packets are replicated downstream with M-
VLAN unchanged.
The OLT replicates multicast packets based on
PON ports with M-VLAN unchanged.
Single- ONTs translate the upstream VLANs sent from
tagged HGW to M-VLANs.
VLAN
The OLT replicates multicast packets based on
PON ports with M-VLAN unchanged.
Single- ONTs transparently transmit the upstream U-
tagged VLANs sent from HGW.
VLAN
The OLT implements VLAN translation: U->S.
Double- ONTs transparently transmit the upstream U-
tagged VLANs sent from HGW.
VLAN
The OLT implements VLAN translation: U->S
+C.
Single- ONTs replicate packets based on user ports and
tagged M-VLANs are removed in downstream
VLAN direction.
The OLT replicates multicast packets based on
PON ports with M-VLAN unchanged.
Single- ONTs add C-VLAN tags to packets (iTMS
tagged system has finished the configuration).
VLAN Untagged VLANs are translated to C-VLANs.
The OLT implements VLAN translation: C ->
