when it connects to an instance of the. Many of the terms used are derived from the TMF 814 object model.Category | Class | Description |
|---|---|---|
Physical Equipment | OpticalNetworkElement | Device supporting SONET/SDH |
Card | Equipment and Card are interchangeable terms. These are physical subsystems that plug into OpticalNetworkElements and support one or more PTPs. | |
Equipment | ||
Ports | PTP | Physical Termination Point. End point of a physical connection. |
Physical Connections | TopologicalLink | A physical connection, such as a fiber link, that connects to another device managed by the. |
DropSideTopologicalLink | A physical connection, such as a fiber link, that connects a device managed by the to another device that is not managed by the. | |
Conduit | Conduit is an aggregated physical connection consisting of multiple links between a pair of devices managed by. | |
Abstract Entities | BBTopologicalLink | An unmanaged segment in the between managed entities. May consist of one or more physical or logical devices. |
BBDropSideTopologicalLink | An unmanaged segment on the edge of the managed entities. May consist of one or more physical or logical devices. | |
Logical Ports | CTP | Connection Termination Point. End point of a logical connection. |
Logical Connections | LogicalConnection | A logical connection that crosses part of a subnetwork such as a protection group. |
SubNetworkConnection | A logical connection that crosses a subnetwork. | |
MeshSubnetworkConnection | A logical connection that crosses a subnetwork that is in a mesh configuration. | |
HighOrder_Trail | A logical connection across a network that may cross one or more subnetworks. | |
HighOrder_Circuit | An end-to-end connection across a network that may cross several subnetworks. This entity is used to represent client services. | |
Protection | TopologicalLinkGroup | A group of TopologicalLinks that form some larger entity such as a ring. |
ConnectionProtectionGroup | A group of TopologicalLinks or TopologicalLinkGroups that provide protection for subnetwork connections that cross the protection group. For example, 2F-BLSR ring configuration. | |
RingProtectionGroup | A group of TopologicalLinks that form 4F-BLSR/4F-MS-SPRing protection configuration | |
LogicalConnectionTPGroup | A group of CTPs that form UPSR/SNCP protection configuration. | |
CardProtectionGroup | A group of Cards (or Equipment) where one or more cards backs up a main card. |
