threshold (SONET)
To set the bit error rate (BER) threshold values of the specified alarms for a SONET controller, use the
threshold
command in SONET/SDH configuration mode. To remove the setting of the threshold from the
configuration file and restore the default condition, use the
no
form of this command.
