NOTE
l To ensure traceability of users and finer-grained QoS control and management of users and services, plan
per user per service per VLAN (PUPSPV) for the Internet access service. Considering OLT capacity and
VLAN scalability, use dual VLANs (S-VLAN+C-VLAN) on the OLT to differentiate users for the Internet
access service.
l The outer S-VLAN, which identifies services and physical location, can be allocated based on the OLT,
PON board, or PON port. The inner C-VLAN identifies users. User C-VLANs must be unique in one S-
VLAN.
l It is recommended that you use stacking VLANs as S-VLANs so that security features, such as PPPoE+/
opton82, and anti MAC attacks and anti spoofing spoofing can be easily deployed.
l The 802.1q in 802.1q (QinQ) VLAN is used in the enterprise private line scenario, such as (TLS). The device
transparently transmits packets. It is not recommended that you use QinQ VLANs as S-VLANs for the triple
play services of residential users.

10.5.4 Principle of Voice Service Data Plan

The voice service plan mainly includes the plan of the VLAN and VLAN translation policy in
different network scenario, and the plan of voice protocol.

VLAN Plan
Double-tagged VLAN
UserVLAN: VLAN carried by upstream packets of user-side devices, U for short.
C-VLAN: VLAN added based on the ONU port. For details, see the description of the
Double-tagged VLAN S+C.
Double-tagged VLAN S+C: C indicates the inner VLAN (C-VLAN) and S indicates the
outer VLAN (S-VLAN).
Double-layer VLAN S+C': C' indicates the translated inner VLAN (C'-VLAN) and S
indicates the outer VLAN (SVLAN).
Single-tagged S-VLAN: Single-tagged VLAN marked or translated by the OLT. It is
generally used in a single-tagged VLAN translation scenario.
C<->S+C': Bidirectional VLAN translation: translates the inner C-VLAN and then adds
one outer S-VLAN.
C<->S+C: Bidirectional VLAN translation: maintains the inner C-VLAN and adds one
outer S-VLAN.

VLAN Translation Policy
ONU: The upstream packets sent from
the HGW carry user-VLANs and the
ONU transparently transmits them.
OLT: The OLT translates the U-VLAN
to S-VLAN+C-VLAN.
