INM Broadband Release 4.1 PG OC 98-13 Issue 1.2
PM Threshold Provisioning
The Performance Management Threshold Provisioning feature provides the
user of INM Broadband Release 4.1 the capability to retrieve and set
performance threshold values through the INM Broadband GUI. INM
Broadband Release 4.1 offers the capability to retrieve and set performance
threshold values through the INM GUI without having to log onto the NE. This
is done through a PM Threshold Provisioning dialog as shown in Figure 8 on
page 47.
Performance threshold values are user identified values associated with
performance management parameters. When a particular performance
management parameter crosses the identified threshold, the NE has the
capability of raising a performance threshold crossing alert or alarm. This
feature provides interfaces to the users to set and query performance threshold
values.
Through the GNB, the user can query and set performance threshold
parameters for DS1, DS3, STS1, OC3, OC12, and OC48 facilities for the
following products:
- NORTEL S/DMS OC-3 TBM (LTE, linear ADM)
- NORTEL S/DMS OC-12 (LTE, linear ADM, ring ADM, Regenerator)
- NORTEL S/DMS OC-48 (LTE, ring ADM, Regenerator)
Depending on the NE and facility chosen, up to two threshold values can be
set for most performance management attribute on a facility. When a threshold
crossing occurs, a threshold crossing performance alarm/alert may be
generated by the network element (the alarms are propagated back to the GNB,
whereas the alerts are not propagated to the GNB, but are logged at the NE UI).
The user can disable PM threshold reporting for an individual PM attribute or
for a group of facilities through the GNB. In addition, this feature also gives
the user the ability to toggle between threshold crossing alarms or alerts.
