CTM is a highly advanced optical transport domain manager. Open interfaces to Operations Support
Systems (OSSs) using industry-standard protocols make CTM a flexible building block in legacy as well
as next-generation OSS infrastructures. The CTM GateWay/CORBA product is a CORBA northbound
interface that complies with the TMF CORBA specification for network management layer-element
management layer (NML-EML) interfaces.
A programming technology for distributed computing, CORBA enables components of various
application programs to communicate with one another regardless of their implementation
characteristics—programming language, operating system, machine, location, and so on.
CTM GateWay/CORBA allows service providers to implement a programmatic interface between CTM
and various OSS tools in the back office. Such interfaces enable next-generation flow-through equipment
and circuit management, including inventory, provisioning, and assurance functions.
For each NE that CTM manages, the CTM GateWay/CORBA option provides higher-layer management
systems with fault, inventory, and performance information, plus configuration and circuit provisioning
capabilities. CTM GateWay/CORBA supports up to eight simultaneous sessions with higher-layer
management systems.
