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.
