cmgDsuStatusMask

Each bit of this value set to '1' indicates a specific status
condition in this DSU, or a fault or status condition in its
associated CSU.
              
Octets are numbered in the order in which they appear in the PDU.
Bits are numbered from the most-significant leftmost bit in the
octet (bit 0) to the least-significant rightmost bit (bit 7).
              
Cajun numbering continues across octets, so that octet 1 bit 0 is
called bit 8 in the Cajun scheme.  That number is also shown below,
with the octet value for each single bit set.
              
If the CSU is reporting a Blue Alarm (AIS), multiple other alarms
may be hidden by the Blue Alarm.
              
--  The four octets of the T1E1 status mask are taken from three different
--  maintenance APIs and assembled by the SNMP agent.
              
Octets 0-1 show CSU fault status.
--  From t1e1csu_status.mask, built by the macro T1E1CSU_STATUS_MKMASK.
--  This is defined in CAPIStructures.h:851 and used in T1E1Csu.C:194.
              
Octet 2 shows CSU loopbacks active.
--  From t1e1csu_lpbkstatus.mask, built by the macro T1E1CSU_LPBKSTATUS_MKMASK.
--  This is defined in CAPIStructures.h:803 and used in T1E1Csu.C:173.
              
Octet 3 shows DSU loopbacks active.
--  From t1e1dsu_tstmgmt.mask, built by the macro T1E1DSU_TSTMGMT_MKMASK
--  This is defined in CAPIStructures.h:1115 and used in T1E1Dsu.C:1574.
--  Note this just copies t1e1dsu_tstmgmt.status_lpbk into the mask field.
--  Don't confuse t1e1dsu_tstmgmt.lpbk and t1e1dsu_tstmgmt.status_lpbk.  The
--  first is what a CLI user requested; the second is what the board reports.
--
--  The bit assignments are chosen to facilitate retrieval from the board.
