The WAVECOM software displays four sub-windows on the screen : “Normal T1/T2”, “Inverse T1/T2”, “Normal T2/T1” and “Inverse T2/T1”. This way of organizing the display is due to the fact that it is not possible for the operator to decide from the monitored tone sequence, whether the first received tone constitutes tone 1 or tone 2 of a character.
