%L – Return received line signal quality
Returns a value which indicates the received signal level. The value returned is a direct indication
(DAA dependent) of the receive level at the MDP, not at the telephone line connector. For example
007= -7dBm, 033 = -33dBm. For leased line the value should be better than -40dBm. The noise
should be at least 6dBm lower than the signal itself in order for the communication to work properly.
