percentage of circuit bandwidth used rather than the percentage of line bandwidth used. Click the
Maintenance > Ether Bridge > Trunk Utilization tabs to view the window. Choose a time segment

9.7 Remote Monitoring Specification Alarm Thresholds
The ONS 15327 features Remote Monitoring (RMON) that allows network operators to monitor the
health of the network with a network management system (NMS). For a detailed description of the ONS
SNMP implementation, see
One of the ONS 15327 RMON MIBs is the Alarm group. The alarm group consists of the alarmTable.
An NMS uses the alarmTable to find the alarm-causing thresholds for network performance. The
thresholds apply to the current 15-minute interval and the current 24-hour interval. RMON monitors
several variables, such as Ethernet collisions, and triggers an event when the variable crosses a threshold
