This object specifies the SNR margin threshold. An
appropriate alarm should be generated when the difference
between the actual SNR and the SNR required to maintain BER
of 10E-7 is less than this value. The value for this object
must be in multiples of 10. The specified value will be
rounded down to the nearest valid tenth dB level if the
value is not in multiples of 10.
If the agent implements the CISCO-ENTITY-ALARM-MIB, the alarm
generated should be through the mechanism defined by the
CISCO-ENTITY-ALARM-MIB. Furthermore, the default severity
of this alarm should be 'minor'.
