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. -(German announcement sais: "Dieser Anschluß ist vorrübergehend nicht erreichbar!") +(German announcement says: "Dieser Anschluß ist vorrübergehend nicht erreichbar!") </p> <p> @@ -710,7 +710,7 @@ Detecting loss of carrier signal: <p> 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 <db>' or '--squelch <db>' to define the squelch threshold level. To measure the noise floor, use the 'm' key to get a bar graph of the current RSSI.
