Some ONTs have limitations that are linked to their package type. Both Package A
and B ONTs have specific limitations that apply only to them.

Upgrade considerations and limitations

Existing ONTs that use 7342 ISAM FTTU releases older than R04.06.xx and
R04.07.xx must be upgraded to use R04.00.10 software while assigned to a PON ID
value smaller than 64. For this purpose, if split ratios larger than 1:64 are being
deployed, you may choose to set aside the first PON ID as a staging point.

Service creation considerations and limitations

Port-to-port mode must be enabled when using the four-port Ethernet ONT I-x4xx-x.
When using port-to-port mode, you can only configure one Ethernet port.

OAM and statistics considerations and limitations

PM_ONTENET counters for SQE, IMTE, and CSE performance monitoring are not
supported.
TC layer OAM performance monitoring is not supported on the OLT R04.00.10
therefore LOSTFRAGS and TXFRAG counters for PONONTTC are not supported
on indoor ONTs.
The REPT-OPSTAT-ONTANI TL1 command which is used to determine the
received optical power of the ONT will only work for RSSI-enabled ONTs.

ONT slot numbering

Even physically integrated ONTs, without removable hardware, are considered to
have slots. In the case of TL1 ONT commands, the UNI specified by the ont_slot
AID number varies depending on the type of ONT.

PM threshold counter resources are allocated as
ONTs and UNIs allow for the possibility of monitoring
PM threshold crossings, even if these are not
enabled by default. Depending on the line type,
different numbers of TCA counter resources are
allocated:
