Table 1. Next Generation WDM object classes
Category	Class	Description
EMS	EMS	The Element Management System.
Physical Equipment	OpticalNetworkElement	Device supporting WDM.
	Shelf	Physical container which holds the equipment.
	Equipment	The manageable physical components of an OpticalNetworkElement such as circuit packs, fans, power supply units and any other type of replaceable unit.
Ports	PTP	Physical T ermination Point. End point of a physical connection.
