Multicasts — Service thresh.
Thresholds are used to determine when to actually raise an alarm upon detection of an error. The
Multicasts — Service thresh.
view makes it possible to define threshold values that operate at service
level. This is particularly useful to specify individual alarm handling rules for services in a multi-program
transport stream (MPTS). Note that if there is a stream and service threshold mismatch, the service
threshold will apply. This may be the case if scrambling or scheduling requirements are set differently in
the stream threshold template and service threshold template associated with a stream.
If the
Extract all services
setting is disabled in the Ethernet threshold that is applied to a stream, any
services not referenced by a Service threshold (even if all service-specific settings are disabled or set to
‘Same as stream’) will be ignored by the VB7880.
In the service threshold template list the ‘Refs’ column displays how many streams are associated with
each service threshold template. Thresholds are associated with each stream in the
Multicasts —
Streams — Edit
view. To add a new threshold setting, click the
Add new threshold group
button and
assign a name and value to the new threshold.
Another way of creating a user-defined thresholds is by highlighting one of the thresholds already defined
and then clicking the
Duplicate highlighted
button.
Deleting a threshold is done by highlighting the threshold that should be removed and clicking
Delete
selected
. Note that the predefined thresholds cannot be deleted or changed.
