To find the remaining port soak time, choose the Maintenance > AINS Soak tabs in card view and click
the Retrieve button. If the port is in the OOS-AU,AINS state and has a good signal, the Time Until IS
column shows the soak count down status. If the port is OOS-AU,AINS and has a bad signal, the
Time Until IS column indicates that the signal is bad. You must click the Retrieve button to obtain the
latest time value.
For more information about port and cross-connect states, see
States."

Circuit Protection Types
Description
The circuit is protected by a 1+1 protection group.
The circuit is protected by a two-fiber BLSR.
The circuit is protected by a four-fiber BLSR.
The circuit is routed on a protection channel access (PCA) path on a two-fiber
BLSR. PCA circuits are unprotected.
The circuit is routed on a PCA path on a four-fiber BLSR. PCA circuits are
unprotected.
The circuit is protected by a both a two-fiber and a four-fiber BLSR.
The circuit is protected by a dual-ring interconnection (DRI).
A circuit with connections on the same node is not protected.
The circuit is routed on a PCA path on both two-fiber and four-fiber BLSRs. PCA
circuits are unprotected.
The circuit is protected by diverse SONET topologies, for example, a BLSR and a
path protection, or a path protection and 1+1 protection.
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 BLSR or 1+1 protection group.
The circuit is protected by a path protection.
The circuit is protected by the protect transponder (TXPP_MR_2.5G) splitter
protection. For splitter information, refer to the Cisco ONS 15454 DWDM
Installation and Operations Guide.
The circuit is protected by a transponder or muxponder card Y-cable protection
group. For more information, refer to the Cisco ONS 15454 DWDM Installation and
Operations Guide.
