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.
