Then the base station returns to the ordered channel and waits 700 ms to 2.1 seconds for the mobile station to send the call acknowledge signal ("Rufbestätigung").
If it is not received, the base station repeats the paging sequence again.
If there is still no call acknowledge signal, it sends a clear signal ("Trennsignal") for at lease 350 ms and returns to idle state and indicates announcement to the calling party that the mobile station is (currently) not available.

This works with SDR only, because we do not have any RSSI (Received Signal Strength Indicator) signal from a radio connected to the sound card.
With SDR we know the RX level, so we can define a threashold value for a lost signal.
With SDR we know the RX level, so we can define a threshold value for a lost signal.
Use '-S &lt;db&gt;' or '--squelch &lt;db&gt;' to define the squelch threshold level.
