Considerations and limitations
When using multicast on multiple Ethernet ports, all Ethernet ports must have the same VLAN ID. If
the user-side VLAN IDs are all given the same VLAN ID, a common VLAN ID should result. If not, VLAN
4094 will be used
Package B ONTs are not able to sufficiently buffer enough traffic between grants to support an EIR
rate of 1Gb/s over multiple GEM ports. There are only 1.256 Gb/s buffers available in the SoC chip.
The buffers are divided among the number of configured GEM ports. Reducing the number of GEM
ports configured results in increased upstream buffering and higher upstream traffic rates.
Packets with less than 72 bytes are increased to exactly 72 bytes in size with padding
Package B ONTs that use pre R04.00.10 software may not range if the distance from the LT card is
less than 1km
After the ONT is In Service, a subsequent edit of the ONT Out-of-Service and back In-Service may
result in a temporary SIPREGDNS Alarm on POTS 2 when the Service change is sequenced in close
timing proximity to a DNS TTL expiry.
