%L – Signal level on line
This command returns an approximate numerical value for the received signal level.
For instance 007 indicates a received signal level at –7 dBm and 033 indicates –33 dBm.
For leased line the value should be better than -40 dBm. This is however depending on the noise
level, which should be at least 6 dBm lower than the signal itself in order for the communication to
work properly.
