This object shows the status of BERT in the shelf. The values for this object are valid only when cbRowStatus contains active(1). Possible values for this object: success(1) : BERT is successfully completed. inSync(2) : BERT is activated and receive side is synchronized with the incoming sequence of patterns. outOfSync(3) : BERT is activated, but receive is out of synchronization with the incoming sequence. Criteria for out of synchronization state is defined in ITU document O.150. inLoopback(4): loopback establish or de-establish in progress. The type of loopback can be determined by cbLoopback. clockOutOfSync(5): When the send and receive clocks are not synchronized. bertFailed(6): BERT failed. The cbFailedReason object contains the reason for the failure.
