Data Type: DS‐72
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 parameter. As soon as the unreported
status is cleared by the alert reporting
procedure, and other block alert may be
reported without clearing the active status, if
the subcode has changed.
