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.
