Viewing G.709 Properties
The Telecommunication Standardization Sector (ITU-T) Recommendation G.709 provides a 
standardized method for transparently transporting services over optical wavelengths end to end. A 
significant component of G.709 is the FEC code that improves performance and extends the distance that 
optical signals can span. 
To view G.709 properties: 
Step 1In the Vision client, double-click the device on which DWDM is configured. 
Step 2In the Inventory window, choose Physical Inventory > Chassis and navigate to the interface configured 
for DWDM.
Step 3In the content pane, click G709 Details. Figure 16-2 and Figure 16-3 provide examples of the G709 Info 
Properties windows. Most devices provide the information shown in Figure 16-2. PM 15-min Settings Click to view 15-minute performance monitoring properties. For more

  Viewing Performance Monitoring Configuration
Step 5To close the G709 Info Properties window, click the upper right corner.
Viewing Performance Monitoring Configuration
Performance monitoring parameters are used to gather, store, set thresholds for, and report performance 
data for early detection of problems. Thresholds are used to set error levels for each performance 
monitoring parameter. During the accumulation cycle, if the current value of a performance monitoring 
parameter reaches or exceeds its corresponding threshold value, a threshold crossing alert (TCA) can be 
generated. The TCAs provide early detection of performance degradation.
The Vision client enables you to view the configuration settings for performance monitoring. 
Performance monitoring statistics are accumulated on a 15-minute basis, synchronized to the start of 
each quarter-hour. They are also accumulated on a daily basis starting at midnight. Historical counts are 
maintained for thirty-three 15-minute intervals and two daily intervals. 
To view performance monitoring configuration settings: 
Step 1In the Vision client, double-click the device on which DWDM is configured. 
Step 2In the Inventory window, choose Physical Inventory > Chassis and navigate to the interface configured 
for DWDM.
Step 3In the content pane, select the performance monitoring configuration settings you want to view:
To view the performance monitoring 15-minute configuration settings, click PM 15-min Settings. 
To view the performance monitoring 24-hour configuration settings, click PM 24-hour Settings. 
The Client DWDM PM Settings Properties window is displayed as shown in Figure 16-4.

Type Optics performance monitoring parameter being tracked:
LBC—Laser bias current.
OPR—Optical power on the unidirectional port.
OPT—Transmit optical power in dBm. 
Max Threshold Maximum threshold configured for the parameter. 
Max TCA If enabled, indicates a TCA is generated if the value of the parameter exceeds the maximum 
threshold during the performance monitoring period. If disabled, TCAs are not generated if the 
maximum threshold is exceeded.
Min Threshold Minimum threshold configured for the parameter. 
Min TCA If enabled, indicates a TCA is generated if the value of the parameter drops below the minimum 
threshold during the performance monitoring period. If disabled, TCAs are not generated if the 
value drops below the minimum threshold.
