Acting as Calling Station
After sending the awake signal, the awaking U-transceiver waits for the acknowledge.
After 12 ms, the awake signal is repeated, if no acknowledge has been recognized.
If an acknowledge signal has been recognized, the U-transceiver waits for its possible
repetition (in case of previous coincidence of two awake signals). If no repetition was
detected, the U-transceiver starts transmitting U2 with a delay of 7 ms.
If such a repetition is detected, the U-transceiver interprets it as an awake signal and
behaves like a device awoken by the far end.
