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.
