wanT1E1StatsUASs

Unavailable Seconds (UAS) are calculated by counting the
number of seconds that the interface is unavailable.  The
DS1 interface is said to be unavailable from the onset of
10 contiguous SESs, or the onset of the condition leading
to a failure (see Failure States).  If the condition
leading to the failure was immediately preceded by one or
more contiguous SESs, then the DS1 interface
unavailability starts from the onset of these SESs.  Once
unavailable, and if no failure is present, the DS1
interface becomes available at the onset of 10 contiguous
seconds with no SESs.  Once unavailable, and if a failure
is present, the DS1 interface becomes available at the
onset of 10 contiguous seconds with no SESs, if the
failure clearing time is less than or equal to 10
seconds.  If the failure clearing time is more than 10
seconds, the DS1 interface becomes available at the onset
of 10 contiguous seconds with no SESs, or the onset
period leading to the successful clearing condition,
whichever occurs later.  With respect to the DS1 error
counts, all counters are incremented while the DS1
interface is deemed available.  While the interface is
deemed unavailable, the only count that is incremented is
UASs.
