WDM Object Classes in Optical Transport Manager

Classes in the WDM object model lists the classes used in the WDM object model of the Optical Transport Manager that are visible in the Global Console when it connects to an instance of the Optical Transport Manager.

Table 1. Classes in the WDM object model
Category	Class	Description
Equipment	Facility	Generic class that represents entities in the network that can be assigned during design of circuits.
Equipment	OpticalNetworkElement	Device supporting WDM.
Cards	Card	Generic class used to represent cards or circuit packs in a network element, including multiplexers and demultiplexers.
	Amplifier	Amplifier card. Can be transmit, receive, or in-line.
	Transponder	Card with transponder functionality. Can have transmit, receive, or both capabilities.
	ControlModule	Models a Controller card.
	MuxModule	Models an OTN multiplexer/demultiplexer card, or a passive filter.
	OcmModule	Models an OTN ROADM Optical Channel Monitor (OCM) card.
	WssModule	Models an Optical Transport Network (OTN) ROADM Wavelength Selective Switch (WSS) card.
Ports	TransponderInOcnPort/ TransponderOutOcnPort	Port on a transponder that faces the client and carries SONET/SDH signals.
	TransponderInOchPort/ TransponderOutOchPort	Port on a transponder that faces a multiplexer and carries an optical channel.
	TransponderInFecPort	Receiving forward error correction (FEC) facility on a transponder.
	MuxInOchPort	Port on a multiplexer that receives an optical channel from a transponder.
	MuxInOmsPort/MuxOutOmsPort	Port on a multiplexer carrying an optical multiplex section. Input will be connected to another multiplexer. Output will be connected to a transmit amplifier.
	DemuxOutOchPort	Port on a demultiplexer that sends an optical channel to a transponder.
	DemuxInOmsPort/DemuxOutOmsPort	Port on a demultiplexer carrying an optical multiplex section. Input will be connected to a receive amplifier. Output will be connected to another demultiplexer.
	AmpInOmsPort/AmpOutOmsPort	Port on a transmit or receive amplifier connected to a multiplexer or demultiplexer.
Ports (continued)	AmpInOtsPort/AmpOutOtsPort	Input and output port of an in-line amplifier.
	AmpInOscPort/AmpOutOscPort	Optical supervisory channel input and output ports on amplifiers.
	PTP	Physical Termination Point. Bidirectional SONET/SDH port.
Physical Connections	TopologicalLink	A bidirectional SONET/SDH link that terminates on a PTP on each of its two ends.
Physical Connections	FiberLink	A unidirectional physical connection, such as a fiber connecting two optical ports.
Logical Connections	LogicalLink	A unidirectional link that corresponds to a link connection or a network connection.
	OcnLink	A logical connection, generally spanning multiple physical components and links, that connects an OCN input port to an OCN output port.
	OchLink	A logical connection, generally spanning multiple physical components and links, that connects an OCH input port to an OCH output port.
	ClientCircuit	A logical connection spanning the entire WDM domain that represents a client’s connection. Wavelength service is a ClientCircuit.
	ClientTrail	Like ClientCircuit, a logical connection between OCN ports, but underlying it. A ClientCircuit may be carried over multiple ClientTrails.
Protection	LinkGroup	A logical grouping of OchLink or OcnLink objects to create a protected ClientCircuit or TopologicalLink.
Abstract Entities	BBFiberLink	An unmanaged, unidirectional connection between managed entities or at the edge of the managed network.
Abstract Entities	PassiveFiberLink	A uni-directional link that generally corresponds a connection between an output port and an input port over passive filters.

The classes are described in more detail in the sections that follow in this chapter.
