10.9 GSM modem Led behavior
Figure 142: GSM level display on led
The modem led default behavior is to go solid red while PPP Is established and off otherwise.
If this option is selected, the modem led will display the signal level as described here:
The led must display 2 informations:
• if the modem is connected.
• the signal reception level.
The representation uses an 8 seconds pattern, the first 4 seconds display the signal level and the last 4 seconds the connection state.
Signal level: the signal level is displayed 4 times. The led goes on between 100msec to 900msec according to the signal level. Then the blink is
repeated 3 more times.
Connection state: for the last 4 seconds, the led is ON if connection is established (PPP connection established). The led is OFF if there is no
ongoing connection.
REM: the signal level displayed here is a rough indication, the exact level can be read from the modem configuration page in the eWON.
