15.4.2 E3-12 Card Performance Monitoring Parameters
15.4.2 E3-12 Card Performance Monitoring Parameters
Figure 15-3 shows the signal types that support near-end and far-end PM parameters for the E3-12 card.
Figure 15-4 shows where overhead bytes detected on the ASICs produce performance monitoring
parameters for the E3-12 card.
