7.4.8 SPY_Synchro_Found
synchronization when it was receiving a sub- -frame. Thus, it is now synchronized and it is waiting for another correct frame
for confirmation.

The SPY_SubFrame is sent by the AMIS- -49587 local PHY layer to indicate that a sub- -frame has been correctly received.
The SPY_Search_Synchro is sent periodically by the AMIS- -49587 local MAC sub- -layer to indicate synchronization is in
The SPY_Synchro_Found is sent by the AMIS- -49587 local MAC sub- -layer as soon as it has correctly found
For the format of the SpyData field, see Table 49.
The SPY_No_Alarm_Found is sent by the AMIS- -49587 local MAC sub- -layer at the end of a time- -slot, when it has not
For the format of the SpyData field, see Table 49.
The AlarmPattern has a length of 2 bytes.
