IIB Mux OSN750 0: S. No Location Function Category Effect of Failure Failure Mode Severity Rating

This document summarizes potential failures in network equipment. It lists 4 potential failures: two failures of OSN750 equipment at locations IIB and FBDE due to dual fiber cuts or power failures, and two failures of OSN350 equipment at locations ISD and KLME also due to dual fiber cuts or power failures. All failures would result in the termination of all media passing through that equipment and would be considered critical. The likely cause is listed as dual fiber cuts or power failures and the potential means of detection is the network management system.
