The Cisco EMS and Ciena EMS Adapters
Query their respective EMSs for SONET/SDH network elements and connectivity information to populate the Optical Transport Manager Topology server repositoryNote:
Currently, only the SONET/SDH and Low Order SONET/SDH adapters support topology population. The WDM Topology server repository is populated via the OTM API.
Registers with the EMS for object create/delete/change events to keep the repository synchronized
Each EMS requires a separately configured adapter. Once you configure the adapter for a vendor’s EMS, the adapter can connect with more than one instance of that EMS.
