This parameter indicates the secondary status of the board. The parameter provides additional information pertaining to PST and PSTQ. For example, it may indicate the type and/or reason of the external command, the event that occurred in the Network Element, etc. Multiple values may apply to an entity at a given moment. The highest bit of SST value indicates the sst-ains(0) status; the second highest bit of SST value indicates the sst-faf(1) status, and the rest can be deduced by analogy. This BITS structure can report the following status: 1. sstAins(0) - This bit position positively reports that the status of the board is automatic in-service 2. sstFaf(1) - Facility failure 3. sstFlt(2) - Fault 4. sstLpbk(3) - Loopback 5. sstMea(4) - Mismatch of equipment and ettributes 6. sstSgeo(5) - Supporting entity outage 7. sstStbyh(6) - Standby-hot 8. sstTs(7) - Test 9. sstUas(8) - Unassigned 10. sstUeq(9) - Unequipped 11. sstWrk(10) - Working 12. sstPwr(11) - Power
