3.0 Registers
3.8 Event/Error Counters
3.8 Event/Error Counters
The 24 counters to count line and interface events or errors are summarized in Table 3-18 and explained in
Tables 3-20 through Table 3-24. The first nine (addresses 0x40–0x48) provide counts of error events from the
line or PHY framers. The events that are counted depend on the mode of operation and are summarized in
Table 3-19. The remaining counters provide counts of ATM cell events.
Counters 5–9 can be programmed to count block errors instead of individual errors for BIP and FEBE status
by setting Count Block Errors (bit 11) in CONFIG_3. This provides support for G.826 performance monitoring.
Register summary cheat sheets are illustrated in Figures 3-2 and 3-3.
