Generally, commercial power is supplied after being stepped down to a voltage such as 60V or 90V. In this case, in order to prevent the power supply to the CATV system from being interrupted even when the commercial power supply fails, the CAT is automatically switched from the standby power supply (storage battery) when the commercial power supply fails.
An uninterruptible power supply for supplying power to the V system is provided.
