Note
l The VoIP service is a closed service self-operated by carriers. The single-tagged S-VLAN
is the mainstream application and is recommended.
l Set an S-VLAN for an entire network, an OLT, a PON board, or a PON port for identifying
services and physical locations. It is recommended that you set different VoIP VLANs for
the OLTs connected to one VoIP SR to avoid an excessively large broadcast domain of the
VoIP SR and convergence switch.
l The outer S-VLAN, which identifies services and physical locations, can be allocated based
on the OLT, PON board, or PON port. The inner C-VLAN identifies services or users.

Without HGWs and with
voice services provided by
the MDU: Each MDU uses
the same S-VLAN for its
voice users.
LAN access with voice
services provided by
HGWs: MDUs translate
user VLANs to C-VLANs.
xDSL access with voice
services provided by
HGWs:
l ATM upstream
transmission: MDUs
translate PVCs to C-
VLANs (PVC <-> C-
VLAN).
l PTM upstream
transmission:
Untagged upstream
packets of HGWs:
MDUs map C-VLANs
based on user ports.
User-VLAN-tagged
upstream packets of
HGWs: MDUs
translate user VLANs
to C-VLANs (user
VLAN <-> C-VLAN).
The OLT transmits packets
transparently.
