15.5 15.5.2 DS1_E1_56 Card Performance Monitoring Parameters
Note If the CV-L(NE and FE) falls in the range 51-61 for EC1,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.

Figure 15-5 shows where overhead bytes detected on the ASICs produce PM parameters for the
DS1/E1-56 card.
