Chapter 15 Performance Monitoring
15.4.1 E1-N-14 Card and E1-42 Card Performance Monitoring Parameters
Figure 15-1 Monitored Signal Types for the E1-N-14 Card and E1-42 Card
Figure 15-2 shows where overhead bytes detected on the application-specific integrated circuits (ASICs)
produce performance monitoring parameters for the E1-N-14 card.
Note The E1-42 card uses the same PM read points. The only difference from the Figure 15-2 is that the
number of ports on the E1-42 equal 42.

The PM parameters for the E1-N-14 card and E1-42 card are described in Table 15-2 on page 15-5
through Table 15-4 on page 15-6.
