摘要: An embodiment of the invention provides communications services to Optical Network Terminals (ONTs) in a Passive (PON) with at least two Line (OLTs). The role these OLTs is autonomously governed based on characteristics upstream signals from ONTs. When an OLT standby mode determines that signal power below threshold, changes its and operates active mode. monitors number are misaligned respective downstream command sent OLT. greater than counts switches operation Through autonomous operation, provide redundancy for PON without added control channel complexity.
