Table 1-13 PON and ONT limitations
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.
Limitations Maximum number Comment
Data UNIs per PON 288 The total number of ENET, VDSL2, CES, and VOIP
UNIs. Create a VOIP UNI for a planned ONT when
VOIPALLOWED=YES.
CESUNI ports per PON 128 —
CESPW services per
PON
128 —
POTS ports per PON 384 —
VIDEO ports per ONT 1 —
IGMP channels per PON 288 Create these channels on VLAN ports only on a GPON
LT.
PM threshold (TCA)
counters per ONT
128 A limitation that is not readily apparent to the user.
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:
• ONT — 1
• VOIP — 1
• ENET — 1
• VDSL2 — 3
