14.10 I-240G-B and I-241G-B standards compliance
I-240G-B and I-241G-B indoor ONTs are compliant with the following standards:
•
802.1p mapper service profile on the upstream
•
G.984 support for GPON interface (framing)
•
G.984.3 support for activation with automatic discovery of a serial number and a
password
•
G984.4 (standard and revised) support for OMCI interface for ONT management
and provisioning
14.11 I-240G-B and I-241G-B special considerations
IGMP packet replication allows the I-240G-B and I-241G-B indoor ONTs to support
IPTV on all four Ethernet channels at the same time.
On a user-side port in flexible mode, downstream multicast traffic will have the
UNI-side p-bit of the parameter DATAPRI configured for the IGMP signaling
channel, unless the DATAPRI value differs between ONT UNIs. In the latter case,
the downstream multicast traffic will retain the p-bit from the PON. On a user-side
port in non-flexible mode, such as translation mode, downstream multicast traffic
will retain the p-bit from the PON. The multicast VLAN ID may differ; see

(1)
Port configuration
One port configured in flexible mode or VLAN translation
mode with a configured IGMP signaling channel
More than one port configured in flexible mode or VLAN
translation mode each with a configured IGMP signaling
channel
More than one port configured in VLAN pass-through mode,
untrusted mode, EtherType/VLAN translation mode, or
EtherType classification mode with some ports in transmit
with tag and other ports in transmit without a tag, and each
port with a configured IGMP signaling channel
All other cases
Note
(1) You can only have one IGMP signaling channel on a port.
Service creation considerations and limitations
Port-to-port mode must be enabled when using four-port Ethernet ONTs I-240G-B
and I-241G-B. When using port-to-port mode, you can only configure one Ethernet
port.

VLAN tagging of downstream multicast traffic
Multicast traffic is tagged with UNI-side VLAN ID of
IGMP-related service.
If the IGMP-related services are configured with the same
UNI-side VLAN ID, then all multicast traffic is tagged with
the UNI-side VLAN ID of their service.
If the IGMP-related services are configured with different
UNI-side VLAN IDs, then all multicast traffic is tagged with
VLAN ID 4094.
The multicast traffic is tagged with VLAN ID 4094.
The multicast traffic retains the VLAN ID from the PON.
