13.0 Threshold Alarms

Horizon Compact Plus provides Threshold Alarms to assist in managing the performance of the system.

Threshold alarms are available for the following parameters, showing default setttings:

RSL (Receive Signal Level) -70 dB for 10 seconds

Bandwidth Utilization 100% for 10 seconds

Dropped Frames (for all data queues) 100% for 10 seconds

In addition to the total Dropped Frames threshold, each of the eight QoS queues can be

allocated an individual threshold alarm

Queue Utilization (for all data queues) 100% for 10 seconds

Each queue can be allocated an individual queue utilization alarm

SNR (Signal To Noise) 0 dB*

Most Threshold Alarms have two associated alarm parameters:

1. Threshold value

2. A time limit over which the Threshold value must be exceeded before the alarm is

reported.

The combination of the value and the time limit is user defined. The proper combination of the two

parameters will prevent false alarms from occurring.

* For the SNR parameter, only the threshold level can be set, the time limit, or hysteresis, being a preset

value.
