Alarm declaration and clearing times

Both ends of a primary rate link should use the same alarm declare time because it is
desirable for both ends of the link to initiate and terminate trunk conditioning at
approximately the same time.
The alarm declare and clearing times can be configured for Frame and Distant faults,
but not for Failed and Error faults, which have fixed times.
Alarm declare time
The alarm declare time determines how long a fault must persist before an alarm is
declared. A longer alarm declaration time is useful when the primary rate link is
subject to frequent short outages. A shorter alarm declaration time is useful when an
alternate path exists so that the length of time that service is disrupted is minimized.
The declaration time ranges from 0.1 to 30 seconds in 0.1-second increments (the
default is 0.8 second).
Alarm clear time
The alarm clear time determines how long a fault must be cleared before a raised
alarm is cleared. A longer alarm clear time is useful when an alternate route exists so
that connections to the primary rate link that declared the fault are not restored until
it appears that the link is stable again. A shorter alarm clear time is useful when no
alternate path exists so that the length of time that service is disrupted is minimized.
The clearing time ranges from 0.1 to 30 seconds in 0.1-second increments (the
default is 10 seconds).
