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.
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.
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.
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.
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.
