Options for combiningreverse powering with battery backup are also described. The present document identifies requirements for POTSsignalling translation when operated over reverse power feed. Start-up protocols are defined that will ensure safeconnection of reverse powered systems. Management requirements for reverse power feed and power combining withinthe remote network node are specified.
