PEF 80902
Functional Description
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.
Acknowledging a Wake-Up Call
If a deactivated device detects an awake signal on U, an acknowledge signal is sent out.
After that, the U-transceiver waits for a possible repetition of the awake signal (in case
the acknowledge hasn’t been recognized).
If no repetition is found, the awoken U-transceiver starts sending U2 after 7 ms from
detecting the awake signal. If a repeated awake signal is found, the procedure in the
awoken U-transceiver starts again.
