This section provides solutions to circuit creation and reporting errors, as well as common timing reference errors and alarms.

1.7.1 Circuit Transitions to Partial State

Symptom An automatic or manual transition of a circuit from one state to another state results in one of the following partial state conditions:

•OOS_PARTIAL—At least one of the connections in the circuit is in OOS state and at least one other connection in the circuit is in IS, OOS_MT, or OOS_AINS state.

•OOS_MT_PARTIAL—At least one connection in the circuit is in OOS_MT state and at least one other connection in the circuit is in IS, OOS_MT, or OOS_AINS state.

•OOS_AINS_PARTIAL—At least one connection in the circuit is in the OOS_AINS state and at least one other connection in the circuit is in IS or OOS_AINS state.

Table 1-25describes the potential cause(s) of the symptom and the solution(s).
