Release Notes

Software Features
This section lists the software features and enhancements introduced in Release 10.6.1.
•
Synchronous Ethernet
Synchronous Ethernet (SyncE) provides synchronized timing to multiple remote network elements (NEs)
without using an external circuit for timing. SyncE provides the required synchronization at the physical
level and uses the Ethernet Synchronization Message Channel (ESMC) to enable traceability of the best
clock source. SyncE clocks are compatible with the clocks used in the SONET or SDH synchronization
network.
SyncE is supported on TNCS and TNCS-O controller cards. You must enable ESMC on an OSC port
to configure it as a clock source.
For more information, see the Synchronizing Node Timing chapter of the Cisco NCS 2000 Series Control
Card and Node Configuration Guide, Release 10.x.x .
•
OTDR Enhancements
◦
Two types of OTDR scans are available for TNCS-O cards: hybrid scan and fast scan.
When you start a fast scan on a TX or an RX port, an OTDR_FAST_SCAN_IN PROGRESS_TX
or an OTDR_FAST_SCAN_IN PROGRESS_RX alarm is raised. Fast scan shuts down the OSC
channel.
When you start a hybrid scan on a TX or an RX port, an
OTDR_HYBRID_SCAN_IN_PROGRESS_TX or an
OTDR_HYBRID_SCAN_IN_PROGRESS_RX alarm is raised. Hybrid scan does not shut down
the OSC channel and takes more time to complete.
◦
New OTDR alarms are introduced to provide more information about the OTDR events which are
cross provisioned with the alarm thresholds.
◦
A list of events that raises alarms is provided to point out the correct sector where the cause of the
event is found. Select an event to view its details as a graph or in a tabular format.
◦
CTC logs the data of a maximum of 32 historical OTDR scans. The history is maintained for OTDR
scans in the same zone and direction. The values of the back reflection and insertion loss are listed
for each scan along with the date and timestamp.
For more information about the OTDR enhancements, see the Cisco NCS 2000 Series Network
Configuration Guide, Release 10.x.x .
•
Connection Verification Enhancements
•
View and troubleshoot patch cords that have an excess insertion loss higher than the threshold
value.
•
View the originating and destination slots for the connection verification along with the patch cords
in the cable view and front panel view of the card.
•
If there is at least one patch cord highlighted in yellow and no patch cords highlighted in orange
on a node, an IPC-VERIFICATION-DEGRADE alarm is raised on the node.
•
If there is at least one patch cord highlighted in orange on the node, an IPC-VERIFICATION-FAIL
alarm is raised on the node.
