Name—Name of the circuit. The circuit name can be manually assigned or automatically generated.
•
Type—Circuit types are: VC high-order path (VC high-order path circuit), VC low-order path (VC

low-order path circuit), VC low-order path (VC tunnel), VAP (VC low-order path aggregation
point), VC_HO_Path_Circuit (high-order path virtual concatenated [VCAT] circuit), or
VC_LO_Path_Circuit (VC low-order path VCAT circuit).
Size—Circuit size. VC low-order path circuits are 1.5. ONS 15310-MA SDH VC high-order path

Circuit Protection Types
Description
The circuit is protected by a 1+1 protection group.
A circuit with connections on the same node is not protected.
The circuit is protected by diverse SDH topologies, for example, a path protection
configuration and a 1+1 protection group.
A circuit has a source and destination on different nodes and communication is
down between the nodes. This protection type appears if not all circuit components
are known.
A circuit with a source and destination on different nodes is not protected.
A circuit created as a fully protected circuit is no longer protected due to a system
change, such as removal of a 1+1 protection group.
The circuit is protected by a path protection configuration.

lists the circuit statuses that may appear.
Definition/Activity
CTC is creating a circuit.
CTC created a circuit. All components are in place and a
complete path exists from circuit source to destination.
CTC is deleting a circuit.
