15.8 15.8 Performance Monitoring for Optical Multirate Cards
Note If the CV-L(NE and FE) falls in a specific range, then, the user might see discrepancy in the SES and the
UAS-L values. However, ES-L will be in the nearest accuracy. For a few seconds, in a given 10 seconds
interval, the number of CV-L counted may not cross the CV count criteria for SES, (due to
system/application limitation for the below mentioned ranges); as a consequence of which there may not
be 10 continuous SES, thus UAS will not be observed. The corresponding (error) range for the line rates
is as shown in Table 15-25.
15.8 Performance Monitoring for Optical Multirate Cards
This section lists PM parameters for the optical mutirate card, also known as the MRC-12 card.
Figure 15-22 shows where overhead bytes detected on the ASICs produce PM parameters for the
MRC-12 card.
