(1) SHDSL LOSW: A condition that generally indicates the loop is down, thus data cannot be transmitted. The
ARL-942 uses this parameter to derive UAS performance
(2) SHDSL ES: Intervals during which at least one CRC is detected at the incoming SHDSL port.
(3) SHDSL UAS: An interval of 1 second during which a loop is down.

Description
SHDSL link has lost
synchronization
Active if the 15 minute ES
count equals or exceeds the
threshold in the current 15
minute interval
Active if the count equals or
exceeds the threshold in the
current 24 hour
interval
Active if the count equals or
exceeds the threshold in the
current 15 minute
interval
Active if the count equals or
exceeds the threshold in the
current 24 hour
interval
Active if the margin equals or
drops below the threshold
Active if the SHDSL band-
width is not sufficient to sup-
port the services provided
by the RT
Active if there is a problem
detected in the SHDSL
overhead channel
Open circuit detected on the
SHDSL span
