Explanation
Option B (FALSE) is correct because when a U1900 PRA trunk is faulty, the SCU (System Control Unit) board is not the relevant component to inspect - the SCU manages overall system control and signaling, not PRA trunk interfaces directly. The appropriate board to check is the PRA interface board (or the E1/T1 trunk board housing that specific trunk), whose indicators would reflect the fault condition. Option A (TRUE) is wrong because it incorrectly assumes the SCU board's indicators correlate with PRA trunk status, conflating system control with trunk-layer hardware faults. A helpful memory tip: match the fault to the function - PRA trunk faults → check the PRA/trunk interface board, not the system Control Unit (SCU). When troubleshooting Huawei gateway hardware, always trace the fault to the board directly responsible for that interface type.
