Auto-retrain.
Determines whether or not the modem
automatically monitors the line quality and requests a retrain
when necessary.
AT%E0 disables line quality monitor auto-retrain
(default)
AT%E1 enables line quality monitor auto-retrain
AT%E2 enables line quality monitor auto retrain and
auto fall back/forward.
Report Received Signal Level.
AT%L 009 = -9 dBm, 010 = -10dBm, etc. all the way to
043 (-43 dBm)
Line signal and noise are determined by the unit of
measurement dBm (decibel referenced to one milliwatt). To
arrive at a signal/noise ratio, the noise level is subtracted from
signal level in dBm.
Report Line Signal Quality . Returns a “high-order” byte of the
calculated EQM (“eye quality monitor”). This can range from
0 to 255. When the value is 8 or greater, the modem will
automatically retrain if enabled by the AT%E1 command. The
value for a normal connection ranges from 0 to 2 and
approaches 8 for a progressively poorer connection. Returns
an OK result code.
000 to 007 no retrain
008 to 255 retrain performed if enabled by %E1.
