5. THE WEB APPLICATION
5.1. Warning
!This unit does not deal with network related security issues. It is up to the user to set it in a secured
environment such as a private network, VPN, behind a firewall…WorldCast Systems cannot be held responsible
for the consequences of a security breach on the operating network.
5.2. Introduction
5.2.1. Working principle
The unit is designed to automatically monitor a DAB channel or a list of DAB channels by comparing measurements
from an internal tuner to user-defined thresholds and reference settings. In case of failure, alarms are generated and
notifications can be sent by SNMP Traps or mail. The unit communicates with the outside world via the IP network It
comes with a client-server application serving as graphic user interface that makes it possible to remotely configure
the unit, view measurements and event logs as well as view realtime measurements and listen to the audio of a
service.
5.2.2. Functions
Cyclical monitoring on multiple programs
Cyclical monitoring is done by setting the tuner successively on each set frequency for acquisition of measurements
and by then comparing the channel reference values with the newly acquired data. Please note that measurements
are collected only once per frequency which explains why a very brief anomaly will not be detected. Each monitoring
element is successively tested according to the hierarchical test order. With this order; lower level tests will not be
performed when a higher level error has been detected. This method also prevents useless alarms from being sent.

Triggering alarms:
This status is then reevaluated with each monitoring cycle as the tests are performed again. When a measured value is
out-of-tolerance, the state switches to ‘ERROR’, but the alarm is not triggered immediately. For each parameter, the
“timeout before alarm” parameter can be configured: it represents a delay during which an error state is tolerated
before the alarm is triggered. Once this length of time has been reached, the state switches to ‘ALARM’, and
corresponding actions are then taken (notification, placement of the event in the event log…)
Switching from ‘ERROR’ to ‘NO_ERROR’ is immediate; however, it takes 2 confirmations to go from ‘ALARM’ to
‘NO_ERROR’, the test must be error free for 2 consecutive cycles.
The hysteresis is an additional factor to be taken into account before the unit returns to normal state after a ‘level’
type threshold violation. This value adjusts the triggering threshold after an alarm begins so that fluctuations near the
threshold level will not continuously trigger alarms. For instance, if we set the high level threshold at 60 and the
hysteresis at 5, the alarm activates at a level higher than 60, and stays on until the level falls below 55.
Triggering and end of a high threshold alarm
‘Intermittent alarm’ type tests detect short but frequent overshoots. A time window and a number of acceptable
overshoots during this time window must be set. For instance, if we do not want more than 5 overshoots within 2
minutes, a counter will start at the 1st overshoot. At the 6th overshoot within the 2 minute window, an alarm is
declared. The state is reinitialized when the number of overshoots within a 2 minute period is lesser than or equal to
5.

Intermittent alarms with a maximum of 4 events within the set time window
Case of alarms ‘closed by hierarchy’
When an alarm with a high hierarchical level is triggered, the state for each lower hierarchical level alarm changes to
‘CLOSED’ and a notification for ‘closed by hierarchy’ is sent. As an example, if an AFLOW alarm is active and the
RFLOW2 alarm gets triggered, an AFLOW trap is sent with an alarmStatus value of 3 (closed by hierarchy).
Inversely, when the high level alarm ends, the lower level tests that were ‘CLOSED’ return to ‘ALARM’ status.

no issue on the channel
When dealing with a series of channels, each channel is monitored for a set time (5 seconds on the example above,
with a 2 second delay before alarm).
Recorded start and end times depend in part on the monitoring cycle.
Channel 1: the error starts second 2 while the channel is monitored and ends second 16 while the channel is also
monitored. Alarm start and end times match actual times.
Channel 2: the error starts second 6 while the channel is monitored and ends second 11 when the channel is no longer
monitored. An error starts again second 18 and ends second 23. The monitoring unit cannot detect the absence of
error between second 11 and second 18. It is seen as a single error. Alarm start time: second 8; alarm end time second
23.
Channel 3: the error starts second 12 while the channel is monitored and ends second 20 when the channel is no
longer monitored. The monitoring unit detects the absence of error when starting to monitor the channel again.
Alarm start time: second 14; alarm end time: second 25.
It is also important to note that when a channel is not monitored, no measurements can be compiled on that specific
channel, leaving blanks in the recorded measurement curves.
As a rule, be aware that the higher the number of monitored channels, the lesser monitoring time is spent on each.
