The Power Stone allows you to reboot remote equipment by phone. This eliminates costly, remote site service calls for locked up equipment. The Power Stone is a telephone activated remote AC power controller and can perform a variety of functions relating to the supply of 120V power to any connected equipment. It enables the user to power up, power down, or reboot remote equipment through a single phone line either automatically or manually and does not need a dedicated phone line to operate. It can be installed on an existing line.
