Package H ONT considerations and limitations

Table
Considerations and limitations
Do not submerge business ONTs. The ONT cannot withstand water submersion caused by flooding.
Equipment damage will occur
The B-0404-A E1 interface supports standard 120 Ω termination via an RJ-48C. Customers that
require a 75 Ω termination need an external adapter
Line loopbacks are not supported
The B-0404-A does not support VLAN translation and VLAN pass-through traffic that uses the same
p-bit across the same UNI or downstream p-bit translation when services are configured in VLAN
pass-through mode
The ONT cannot forward CCM packets to the edge router
The ONT does not support RIPv2 or SAPv1 packets on an unicast VLAN that is not the multicast GEM
port
The ONT cannot perform subscriber join IGMP CAC check when LT-to-ONT signalling is disabled
IPv6 DSCP-to-Pbit mapping supported for B-8102G-A, B-8112G-A, I-820G-D, O-820G-D, O-821G-D,
I-240G-A

Package I ONT considerations and limitations

Table
Considerations and limitations
When in channel package mode, ONT only supports group aging time less than 80 seconds
ONT only supports 77.676 MHz common clock
No support for asymmetrical traffic class provisioning when enabling pbit translations and a different
pbit is carried in different a GEM port. In the downstream direction, traffic with a particular pbit is
allowed only when it's used as network side pbit in upstream. If multiple pbits are carried in the
same GEM port, they can always pass through in the downstream direction.
The ONT always identifies the VLAN tag by TPID 0x8100 and do not support TPID rewriting
In case of VLAN translation, double-tagged packets cannot pass through the ONT. The ONT can only
pass double-passed packets without modification. Triple-tagged packets and S-tunnel mode are not
supported.
ONT can only support the following two different VLAN actions:
•
IP (including IP in PPPoE) untagged packets
•
non-IP (for example, ARP)
No support for flexible VLAN operations-based on the EtherType.
No support for IEEE 802 LLC/SNAP frame format
