Monitoring: All Interfaces; Adjusting Alarm Thresholds: All Interfaces - BridgeTech VB20 User Manual

5.3 Monitoring: All Interfaces

When input signal parameters have been set, the signals may be monitored.
For Ethernet input the relevant monitoring views are: Main, Alarms, Mon, MW,
Traffic, Ethernet. If the probe is equipped with the ETR 290 and/or the OTT option
then the views ETR 290 and OTT are of relevance as well.
For ASI input the relevant monitoring views are Alarms , ETR 290 and ASI - Status.
For demodulator inputs the relevant monitoring views are Alarms, ETR 290 and
COFDM/QAM/VSB/RF/SAT - Status.
Ethernet monitoring hints are found in Appendix II.

5.4 Adjusting Alarm Thresholds: All Interfaces

When probe inputs and streams have been defined using default thresholds, the result
will usually be a number of more or less permanent probe alarms, and not all of them
are informative. In order for the user to get rid of unwanted alarms, the probe provides
alarm filtering functionality in the form of alarm thresholds and alarm on/off selection.
By default Ethernet thresholds are set to raise alarms when service affecting errors
occur, that are caused by the network. There may however be reasons for these
thresholds to be altered, for instance to reflect receiver robustness in the case of IAT,
or to reflect a TS into IP mapping different from the default (7TS/UDP).
Creating a new threshold template is done either by copying an existing one and
altering the copy, or by creating a new threshold template from scratch. The Ethernet
thresholds are defined in the Ethernet - Ethernet thresh. view. These thresholds
are associated with streams in the Ethernet - Multicasts view.
In addition to the miscellaneous thresholds, that affect only the streams with which
they are associated, the Alarm - Alarm setup view allows the user to enable and
disable alarms on an overall basis. It is also possible to define the alarm severity levels
for different alarms in this view.
