27.4 Special considerations
The VLANs between the ONT and the dongle are fixed:
• VLAN ID 35 carries the IP multicast stream from the ONT to the subscriber.
• VLAN ID 38 carries the RF return path from the subscriber to the ONT.
To ensure the proper mapping of the VLANs from the subscriber-side to the
network-side, the following configurations are required:
• Two HSI services are needed: one to carry the IP multicast stream from the PON
to the subscriber, and the other to carry the RF return path from the subscriber to
the IPTV service provider.
• The ONT UNI ports that support the HSI services must be configured for VLAN
translation mode in the QoS marker profile.
• The HSI services must be properly configured so that:
• VLAN ID 35 maps to the IPTV C-VLAN on the PON
• VLAN ID 38 maps to the RF return path (AMR) C-VLAN on the PON
• The AMR PON C-VLAN must be configured in pass-through mode.
Figure 27-1 illustrates the mapping of dongle VLANs in the upstream direction.
