Table 21-1
Circuit Protection Types
Protection Type
Description
1+1
The circuit is protected by a 1+1 protection group.
2F BLSR
The circuit is protected by a two-fiber bidirectional line switched ring (BLSR).
4F BLSR
The circuit is protected by a four-fiber BLSR.
2F-PCA
The circuit is routed on a protection channel access (PCA) path on a two-fiber
BLSR. PCA circuits are unprotected.
4F-PCA
The circuit is routed on a PCA path on a four-fiber BLSR. PCA circuits are
unprotected.
BLSR
The circuit is protected by a both a two-fiber and a four-fiber BLSR.
DRI
The circuit is protected by a dual-ring interconnect (DRI). This is used for both path
protection and BLSR DRIs.
N/A
A circuit with connections on the same node is not protected.
PCA
The circuit is routed on a PCA path on both two-fiber and four-fiber BLSRs. PCA
circuits are unprotected.
Protected
The circuit is protected by diverse SONET topologies, for example, a BLSR and a
path protection, or a path protection and 1+1.
Splitter
The circuit is protected by the protect transponder (TXPP_MR_2.5G) splitter
protection. Refer to the
Cisco ONS 15454 DWDM Installation and Operations
Guide
.
Unknown
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.
Unprot (black)
A circuit with a source and destination on different nodes is not protected.
Unprot (red)
A circuit created as a fully protected circuit is no longer protected due to a system
change, such as removal of a BLSR or 1+1 protection group.
Path protection
The circuit is protected by a path protection.
Y-Cable
The circuit is protected by a transponder or muxponder card Y-cable protection
group. Refer to the
Cisco ONS 15454 DWDM Installation and Operations Guide
.

Definition/Activity
CREATING
CTC is creating a circuit.
DISCOVERED
CTC created a circuit. All components are in place and a complete path exists
from the circuit source to the circuit destination.
DELETING
CTC is deleting a circuit.
