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