A 32 bit mask giving the current status of the ring by specifying the events/status currently present. Bit 1 - Signal-failure on Ring Port 1 Bit 2 - Signal-failure on Ring Port 2 Bit 3 - Remote-signal-failure received on Ring Port 1 Bit 4 - Remote-signal-failure received on Ring Port 2 Bit 5 - Rpl-blocked Bit 6 - Wait-to-restore-timer-running Bit 7 - Hold-timer-running Bit 8 - Guard-timer-running Bit 9 - Periodic-timer-running Bit 10 - Wait-to-block-timer-running Value 1 of the bit signifies the presence of the event associated with that bit and value zero signifies the absence of that event For example: If a signal failure is received on Ring port 1 and R-APS(SF) is received on port 2, then Bit 1 and 4 will have the value as 1. Signal failure on a port represents Port failure indication received from the monitoring entity. This does not depend on hold off timer status. If signal failure is received on ring port 1 and hold-off timer is started, then both Bit 1 and Bit 7 will have the value as 1. Bit 9 indicates periodic timer and Bit 10 will have the value 1 when WTB timer is triggered.
