Automation and Redundancy
Automation and Redundancy
Description
The ROSA™ Element Manager’s Digital Headend
Backup Task provides device or transport stream
redundancy backup in a digital headend.
The task analyzes the headend topology and
divides it into a number of sections related to
certain functionality.
Backup operation is triggered with a device alarm,
an I/O contact closure using UDD or via a channel
alarm of Scientific-Atlanta’s LM 860™ Line
Monitoring device.
Depending on the number of predefined alarm
triggers, an alarm correlation is performed for the
different alarms over a predefined observation
interval.
Based on the diagnosis, a number of backup actions are performed on the devices. Afterwards, a post evaluation
of the system is done to search for remaining alarms.
The operator has full control of the task. The task can be activated or stopped, sections can be locked to prevent
backup operation in case of alarm, manual restore of sections in backup, and so forth. The task logs messages
for every action that is performed.
