Cable System Facts - Performance

AJC has incurred only one submarine fault since the networks Ready for Service (RFS) in December 2001. This submarine event was a shunt fault on one of AJC's two landings into Japan. During the repair of this shunt fault, which took approximately seven days, the protected traffic was ring switched via the other Japan branch and the unprotected traffic experienced an outage. Otherwise, minor cable terminal equipment anomalies within inherent component reliability have been experienced but automatic span switching within tens of milliseconds has avoided interruption to availability of AJC's Protected SDH capacity.

Monitoring of the performance of AJC since RFS by the NOC and cable stations has demonstrated that the performance of the optical transmission, the SDH capacity and the network management capabilities are all meeting or better than specified levels.
