  • Buffering of events being sent between components of Optical Transport Manager

  • Ability to retrieve northbound alarms that were held after a communications failure

  • Ability to retrieve active southbound alarms after connection with an EMS is interrupted

  • Ability to switch to a peer EMS instance in the case of failure

  • Rediscovery of devices after failure of EMS/device communication
