What is difference between mode and state?
In many article we can see the term use of mode, like sleep mode, deep sleep mode. then again, we can find state, such as listen state, transmit state and reception state. I am wondering what the difference between these two (mode and state).
In case of a mobile terminal or a Optical network unit (ONU), the node (MT/ONU) moves into sleep mode. Sleep mode has two states: Listen state and sleep state. In the listen state it scans the beacon message from the BS/Optical Line terminal (OLT), while in the sleep state the radio transceivers are off. Please tell me whether my understanding is right or not.
