15.4.3 DS3i-N-12 Card Performance Monitoring Parameters
15.4.3 DS3i-N-12 Card Performance Monitoring Parameters
Figure 15-5 shows the signal types that support near-end and far-end PM parameters for the DS3i-N-12
card. Figure 15-6 shows where overhead bytes detected on the ASICs produce performance monitoring
parameters for the DS3i-N-12 card.
