ONT Product Information Guide
• G.984.3 compliant multicast using a single GEM port-ID for all video traffic (as
mandated by G.984.3)
• up to of 64 video multicast streams per ONT
IGMP snoop
The ONT supports an IGMP snoop facility. The IGMP snoop facility snoops (looks
into) upstream join and leave messages, and maintains the multicast forwarding
database supported by the ONT hardware, which keeps track of the IP multicast
streams that subscribers are currently viewing.

Table 3-4 lists specifications for the ONT voice service.
Table 3-4 Voice service specifications
Note — For ONTs that have SoC technology on-board in a
two-Ethernet port device, only one Ethernet UNI port at a time can be
configured for IPTV and multicast streams.
Note — The IGMP snoop facility only drops an IGMP message if the
IGMP message rate limit is exceeded.
