AUTOSWTIMREF
AUTOSWTIMREF (Automatic Switch Timing Reference)
The OT port has detected an AUTOSWTIMREF condition at the LINEREF layer. A
LINEREF detects LINEREF during the automatic switch of a timing reference due to
failure, or quality change/priority changes of timing references.
Severity NA

/STM-
n
port has detected a BER that exceeds
selected threshold. The default value is 10

STM-1), and 10
-7
for STM-256.
