If the majority vote method of error correction is selected, the OCU-DP card will monitor data
traffic coming in from the T1 network and use the majority-vote algorithm to determine if any
data errors have occurred. Any data errors that are observed are considered "input" data errors
and contribute to the input error statistics such as Input Errored Seconds (IES), Input Severely
Errored Seconds (ISES) and Input Consecutive Severely Errored Seconds (ICSES). Since the
majority vote algorithm assumes that it can correct any data input errors, the "output" data
error category has no meaning in this context. Consequently, the Output Errored Seconds
(OES), Output Severely Errored Seconds (OSES) and Output Consecutive Severely Errored
Seconds (OCSES) fields do not apply to the majority vote mode.
