scope:

The present document defines architectures and specifications for reverse powering of remote network nodes from one or multiple CPEs over twisted pair networks. The architectures describe how to combine reverse power feed with the data only, VoIP and POTS line services. Start-up protocols are defined to ensure proper interaction between the line services and the reverse power system. Operations and maintenance requirements for managing the reverse power feed and power combining within the remote network node are specified. The present document also identifies power splitter and POTS Adapter requirements.
