Table for getting information on the individual
modems on a Digital Modem Card. The index is
dmcModemIndex, which is the ifIndex value for the
particular modem. Each Digital Modem Card has
12 modems on it.
The instantaneous eye quality measurment (EQM) reported
by the modem for the current call. The EQM is a measure
of the quality of the signal being received by the modem.
Lower values indicate a lower error rate, and are better.
Higher values will cause the modem to reduce the modulation
rate. The absolute values are not comparable between
different modem protocols (V.32bis, V.34, etc.).
The received signal strength at the modem. The units
are dBm (decibels relative to one milliwatt). Low values,
such as -50 dBm, indicate a weak signal, higher values
such as -10 dBm indicate a normal signal. High values
such as 0 dBm indicate a signal that is too strong.
(This is the same measurement as the serialLineAGC in
the SHIVA-LINE-MIB, but the sign has been flipped to
be numerically correct.)
This trap is generated when the system
determines that an individual modem on the
Digital Modem Card that had previously failed
diagnostics is operational again. It is not
generated when the modem comes up at system
startup; that would be too many traps at once!
