9.2.2. OCh Current Performance Statistics
9.2.2.1. OCh Monitoring Parameters Introduction
Monitoring parameters of OCh monitoring points include maximum differential group delay (DGD), maximum
differential group delay (DGD) time stamp, minimum differential group delay (DGD), minimum differential
group delay (DGD) time stamp, average differential group delay (DGD), maximum chromatic dispersion (CD),
maximum chromatic dispersion (CD) time stamp, minimum chromatic dispersion (CD), minimum chromatic
dispersion (CD) times tamp, average chromatic dispersion (CD), maximum optical signal-to-noise ratio (OSNR),
maximum optical signal-to-noise ratio (OSNR) time stamp, minimum optical signal-to-noise ratio (OSNR),
minimum optical signal-to-noise ratio (OSNR) time stamp, average optical signal-to-noise ratio (OSNR),
suspicious interval marker, running time and reset operation. The performance parameters of OCh will be
enabled or disabled at the same time.

9.2.2.2. View OCh Monitoring Information
Only when WDM optical module is inserted can OCh monitoring point and related data exist.Select the
appropriate network elements, slots, ports and monitoring cycle through the selection box above the menu,
the OCh value of a certain network element/slot/port will be displayed. OCh includes only one monitoring point
which is entrance-near end. WDM module is inserted into the monitoring port. OCh data and corresponding
generation time which are currently read will be displayed. After the port is enabled, the suspicious interval
marker should be untrustworthy. The running time counts from 0. After 900 seconds, the suspicious interval
marker will become trustworthy and the running time counts again from 0. The last 15-minute data
automatically becomes the history data.
