Description
ROSA™ Element Manager’s Analog Headend Backup
Task provides automatic backup for outgoing TV channels
in the case of a receiver or modulator failure.
The Analog Headend Backup Task has two parts:
a receiver backup and a modulator backup. Both backup
software modules work independently, but if required, they
can exchange information. The modulator backup module
also includes backup for up-converters.
The task uses equipment alarms and alarms from the
Scientific-Atlanta’s Line Monitoring device LM 860™ to
trigger the reroute of the signals to the available backup
equipment.
Point-to-multipoint topologies are also supported. The
frequency plan of the remote site(s) can be different from
the frequency plan of the local site.
