9.6.4 Principle of Voice Service Data Plan
The voice service plan mainly includes the plan of the VLAN and VLAN translation policy in
different network scenarios, and the plan of voice protocol.

ONT
Single-tagged VLAN
(recommended)
ONT: VLANs are configured for the
ONTs on the same network in a unified
manner, and the ONTs have the same C-
VLAN. The ONT adds a C-VLAN tag to
packets.
OLT: transparently transmits the VLAN.
Double-tagged VLAN
ONT: VLANs are configured for the
ONTs on the same network in a unified
manner, and the ONTs have the same C-
VLAN. The ONT adds a C-VLAN tag to
packets.
OLT: adds an S-VLAN tag to the packets
(C-VLAN <-> S-VLAN+C-VLAN).
Double-tagged VLAN
ONT: VLANs are configured for the
ONTs on the same network in a unified
manner, and the ONTs have different C-
VLANs. The ONT adds a C-VLAN tag
to packets.
OLT: adds an S-VLAN tag to the packets
(C-VLAN <-> S-VLAN+C-VLAN).
Bridging ONT
+HGW
Single-tagged VLAN
(recommended)
ONT: Packets that are sent upstream by
the HGW are tagged with a user VLAN.
The ONT transparently transmits the user
VLAN.
OLT: translates the VLAN tag (user
VLAN <-> S-VLAN).
Single-tagged VLAN
ONT: Packets that are sent upstream by
the HGW are tagged with a user VLAN.
The ONT translates the user VLAN (user
VLAN <-> S-VLAN). All the ONTs
connected to the same OLT have the
same voice service S-VLAN; ONTs
connected to different OLTs may have
different voice service S-VLANs.
OLT: transparently transmits the VLAN.
