  • Publication number: 20250294274
    Abstract: A communication method leveraging service margin aware thresholds of optical alerts within an optical communication network line system is provided. The method includes determining an optical margin for a service provided between a source transponder and a destination transponder through an Optical Line System (OLS). The communication method includes monitoring PMs and fixed predetermined thresholds to raise a threshold crossing alert (TCA) indicating a monitored PM has crossed a fixed predetermined threshold. The method also determines a Service Margin Aware OLS TCA Threshold (SMAOTT) that is unique to a service or location within the OLS, monitors PMs and the determined SMOATT at a network element within the OLS, and raises a specific TCA associated with a SMAOTT when a monitored PM satisfies the SMAOTT.

  • Patent number: 10708141
    Abstract: Disclosed is a method of commissioning a tributary blade in a disaggregated network system, including assigning a port ID to a port of an MCU, mapping to a port map a virtual slot ID to the port ID, receiving a registration request from a tributary blade, and assigning the virtual slot ID to the tributary blade. Disclosed is a method of determining whether a mis-cabling condition exists, including determining the whether a virtual slot ID is mapped to a port ID in a port map. Disclosed is a disaggregated network system including an MCU, a first and second tributary blade coupled to the MCU at a first and second port. The MCU is operable to assign a first and second virtual slot ID to the first and second tributary blades. The MCU is operable to map a first and second virtual slot ID to a first and second port ID.

  • Patent number: 9699023
    Abstract: In accordance with some embodiments of the present disclosure, a method for initializing a network interface comprises monitoring a stream of data sent to a network interface and determining that a provisioning update for the network interface is complete. The method may further comprise sending provisioning data to a local file of the network interface, storing the provisioning data in the local file, and initializing an interface control module of the network interface based on the provisioning data stored in the local file.
