At least one Service Application and one Equipment Module must be added to the engine to make the product operational. The CPC engine provides the infrastructure that supports the Equipment Modules and Service Applications. The engine provides technology specific resource models that simplify the Service object by providing a high level interface across equipment. The standard resource model contains objects that can be used to model any network technology, and is the base from which all technology resource models are derived. It dictates a common information model for all objects in all Equipment Modules.
Logical ports terminate trails and cross-connections.
A technology resource model is a standardized representation of a given technology, which is used by all Equipment Modules supporting that technology. The resource model includes a set of object definitions, with attributes and functions, which a Service can use to request resources of that technology. This includes attributes which represent CoS in an equipment-neutral way, for use by threading functions. An Equipment Module which supports a given resource model must support all of the attributes and functions dictated by the resource model. The Equipment Module model can also have additional objects, attributes, and functions not present in the resource model, to add vendor-specific features.
