Abstract:
1. A system for providing communications services in a Passive Optical Network (PON), the system comprising: a primary Optical Line Terminal (OLT) in an active mode optically coupled to an Optical Splitter/Combiner (OSC), the OSC optically coupled to Optical Network Terminal (ONTs); and a secondary OLT, optically coupled to the OSC, monitoring upstream signal power and configured to autonomously enter an active mode from a standby mode in response to detecting a level of upstream signal power below a power threshold or to detecting no upstream signal power from the ONTs and further configured to operate in the standby mode in response to detecting a number of misaligned signals from the ONTs greater than a counts threshold relative to a downstream signal sent to the ONTs from the secondary OLT.
