This read-only enumerated value reports the current state of the card's Peabody bus LSB (least significant bus) state machine, one of idle, waitForBus, or monitoringBus. An admin checks this to see whether a TDM card is actively arbitrating for or already monitoring the internal Peabody backplane bus, which helps diagnose why a card isn't passing traffic. For example, a card stuck reporting waitForBus(2) instead of progressing to monitoringBus(3) would suggest the card cannot gain access to the shared Peabody bus, pointing to a backplane or arbitration fault.
