A background CMC audit checks this mechanism. The CMC diagnostics quickly identifies the mechanism. Central control software induced accuracy failures The CC software problems can create accuracy failures if correct protocols are not followed.
  • Page 36 1-18 Maintenance overview Manual activity accuracy failures When you or the system sets a network OOS, the network continues to monitor calls in progress for accuracy on the OOS speech path. Due to the potential number of calls on a network, the system does not attempt to notify all PMs involved.
  • Page 37 Maintenance overview 1-19 In-service trouble faults Accuracy failures are a major source of ISTb faults. The transmitting PM continuously sends an accuracy code to the receiving PM. If part of the network fails, the accuracy code can distort. This distortion causes an accuracy failure.
