BLOCK_ERR
This parameter reflects the error status associated with
hardware or software components associated with a
block. It is a bit string, so that multiple errors may be
shown.

BLOCK_ALM
The block alarm is used for all configuration, hardware,
connection failure or system problems in the block. The
cause of the alert is entered in the subcode field. The
first alert to become active will set the Active status in
the Status attribute.
