13.3.1.
LED “UART1” (D100)
This green LED indicates the state of the UART1 power supply.
The interface can be used when it is lit, depending on which power supply is present (J600 or J604;
see section 7 for more information).

LED “RING INDICATOR” (D101)
The “RING INDICATOR” indicator is a yellow LED controlled by the ~CT125-RI1/GPIO42 signal
provided by the WMP150.
It is possible to activate a « visual » mode with AT Command
