Technical requirements for automatically switched optical network (ASON) management -
Part 3: EMS-NMS interface function
1 Scope
This part specifies the interface function requirements related to the control plane management in EMS-NMS interface functions, mainly including the configuration management interface function, alarm management interface function, performance management interface function, and security management interface function.
This part is applicable to the EMS-NMS interface of ASON management system.
This part does not cover the interface function requirements related to transport plane management in the NMS-EMS interface function. For SDH network, see YD/T 1289.4-2006 Synchronous digital hierarchy (SDH) transport network management system technical specification - Part 4: EMS-NMS interface function for the relevant contents of interface function requirements related to the transport plane management; for OTN network, the interface functional requirements related to transport plane management need to be studied.
