Bits 0 to 15: CP-Bit Parity Error Count (CPE[15:0]). This count register contains the value of the internal CP-bit
parity error counter latched during the last error counter update. The internal counter counts the number of DS3
CP-bit parity errors. In E3 mode or M23 DS3 mode this counter is meaningless and should be ignored. A CP-bit
parity error is defined as an occurrence when the majority-decoded state of the three CP bits does not match the
parity calculation made on the information bits. Through the ECC control bit in the T3E3CR2 register, the counter
can be configured to either continue counting CP-bit parity bit errors during an OOF event or not.

Bits 0 to 15: Far-End Block Error Count (FEBE[15:0]). This count register contains the value of the internal
FEBE counter latched during the last error counter update. The internal counter counts the number of DS3 far-end
block errors (FEBE). In E3 mode or M23 DS3 mode this counter is meaningless and should be ignored. A FEBE is
defined as an occurrence when the three received FEBE bits do not equal 111. Through the ECC control bit in the
T3E3CR2 register, the counter can be configured to either continue counting FEBE occurrences during an OOF
event or not.
