CRC Error Count—Indicates the total number of received CRC errors detected by the receive
framer and increments by one for each received DSL 6 ms frame that contains CRC_ERR
[RSTATUS_2; 0xE6]. CRC_CNT is cleared to 0 by ERR_RST [0xD9], and error counting is
suspended while the receive framer is OUT_OF_SYNC or SYNC_ACQUIRED. CRC_CNT
also sets CRC_OVR [RSTATUS_2; 0xE6] upon reaching its maximum count value of 255.
Far End Block Error Count—Indicates the total number of received FEBE errors sent by the
far end transmitter and increments by one for each received DSL 6 ms frame that contains an
active (low) FEBE bit. FEBE is the second IND bit received within the Indicator bit group and
can be monitored separately as the RIND[1] bit in the RIND_LO [0xE2] Receive Status
register. Refer to the DSL Frame Format subsection, Table 2, for the FEBE bit position within
the frame. FEBE_CNT is reset to 0 by ERR_RST [0xD9], and error counting is suspended
while the receive framer is OUT_OF_SYNC or SYNC_ACQUIRED. FEBE_CNT also sets
FEBE_OVR [RSTATUS_2; 0xE6] upon reaching its maximum count value of 255.
