You can enable or disable counters using TL1. Counters are disabled by default
unless indicated otherwise. Some counters have restrictions for the total number that
you can activate at the same time. See the operations and maintenance
documentation for the OLT for information about any restrictions that apply to each
performance statistic type.
Monitoring thresholds and levels
For many performance management statistics retrieved using TL1, some or all of the
following filter criteria apply. With a filter applied, only a matching subset of
statistics counters are collected and displayed.
1 Monitoring level using the monlev parameter values [level, direction]. Only
monitored values that meet the threshold specified are displayed. Where level is
the threshold level and is an integer value (0...4294967295) and direction is a
direction UP or DN. 1-UP is the default.
When the level is >=0, the value represents the threshold of statistics counter to
show. When the direction is UP or DN, the value represents increase/decrease
from threshold for counter to show.
For example, a configuration of [5,UP] would show only counters with values
>=5, while a configuration of [10,DN] would show only counters with values
<=10.
2 Facility location using the locn parameter values [NEND, FEND]. Where NEND
if near end and FEND is far end.
3 Direction using the dirn parameter values (TX or RX) for the transmit or receive
direction.
4 Monitoring period of either 15 minutes or 1 hour intervals.
Counters
Counters are either interval-based counters or rolling counters.

Note —
When the system date changes; for example, due to the move
to daylight saving time, performance statistics collection is affected
and an interval is either repeated or lost.
Note —
A performance monitoring limitation exists for threshold
counters per ONT with a maximum of 128. This limitation is not
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
