Alcatel-Lucent 7302 Information Manual page 925

Considerations and limitations
The ONT will not support sending some untagged multicast frames through one Ethernet UNI while
sending other tagged multicast frames through another Ethernet UNI.
Double-tagged frames are not supported
Flow control is not supported. The ONT will not generate PAUSE frames for the client if there is
traffic congestion.
Configurable Ethernet for VLAN tag detection is not supported. Currently, only 0x8100 is supported.
POTS pull-break-dial-tone (PBDT) is not supported for SIP, H.248, and G6
Call history data collection (ONTCALLHST) is not supported
G.729 and G.711 a/u are supported while G.726-32 codec is not supported
Only one global DSCP to pbit mapping table is supported
Default Ethernet flow and wildcard Ethernet flow coexisting on the same Ethernet port is not
supported
Maximum of 16 service flows (VLANs) can be enabled with pbit translation
Non-supported call services:
•
Direct connect
•
Warm line
•
Call forward status indications
•
Home Intercom
•
Call park
•
Bridged line
•
Call pickup with barge-in
•
Suppressed ringing
Service classification by Ethertype is not supported
The first time an ONT is connected, the initial Ethernet UNI is enabled by default. This Ethernet UNI
can be disabled by the OLT.
When pbit translation is enabled, each GEM port can only translate into one pbit. Mapping
downstream Pbits to different GEM ports is the only form of supported pbit translation.
Static multicast is not supported
IPTV multicast over PPPoE (from the multicast port) is not supported
PM counter is partially supported
Pbit translation following DSCP to pbit mapping is not supported
Pbit translation when a UNI is set to pass through any VLAN ID (unisidevlan=4096 and
networksidevlan=4096) is not supported
Packet loss occurs in 1G wirespeed. Due to the additional 4-byte routing tag, throughput is less than
1G for all packet lengths.
Weighted round robin (WRR) is not accurate when configured with OMCI because the weight
definition in BL device is the reverse of OMCI definition
For WRR scheduling, bandwidth is not used by a queue can not be claimed by any other queues
Up to eight extended VLAN rules per VLAN port is supported
AES key can not be changed locally on an ONT
