Aggressive mode
Example one: at initial time, all power supply statuss are all power supply state.
Do not have the line message to import into by reception interface 13 until leading-in end 113 is discovered, the first R-T unit 11 just switches to power down mode with transmission end 111 and receiving terminal 112, also therefore causes the receiving terminal 122 that does not have message to import the second R-T unit 12 into.So the second R-T unit 12 also makes transmission end 121 and receiving terminal 122 switch to power down mode.At this moment, this R-T unit 11,12 can't carry out communication.
Then, until discovering, leading-in end 113 have the line message to import into by reception interface 13, the first R-T unit 11 just switches to power supply state again with transmission end 111 and receiving terminal 112, this will have message to import into so that the second R-T unit 12 is discovered because of receiving terminal 122, and make transmission end 121 and receiving terminal 122 all switch to power supply state.At this moment, this R-T unit 11,12 can carry out communication by Fabric Interface 14, correctly to receive and dispatch message.
Example two: see also Fig. 2, communication device 2 also comprises a monitoring interface 25, makes the second R-T unit 12 can know at any time the operative scenario of the first R-T unit 11.At initial time, all power supply statuss are all power supply state.
Do not have the line message to import into until leading-in end 113 is discovered, the first R-T unit 11 just switches to power down mode with transmission end 111 and receiving terminal 112.Then, the second R-T unit 12 knows that by monitoring interface 25 the first R-T unit 11 is in power down mode, and makes transmission end 121 and receiving terminal 122 switch to power down mode.
Then, have the line message to import into until leading-in end 113 is discovered, the first R-T unit 11 just switches to power supply state with transmission end 111 and receiving terminal 112.Then, the second R-T unit 12 knows that by monitoring interface 25 the first R-T unit 11 is in power supply state, and makes transmission end 121 and receiving terminal 122 switch to power supply state.
This example also can be that the second R-T unit 12 knows by monitoring interface 25 whether leading-in end 113 receives the line message and decide.
Example three: see also Fig. 2, communication device 2 also comprises a monitoring interface 25, makes the second R-T unit 12 can order the first R-T unit 11 to enter which power supply status.At initial time, all power supply statuss are all power supply state.
When the order of the second R-T unit 12 enters power down mode, the first R-T unit 11 makes transmission end 111 and receiving terminal 112 switch to power down mode, and the second R-T unit 12 also makes transmission end 121 and receiving terminal 122 switch to power down mode.
When the order of the second R-T unit 12 enters power supply state, the first R-T unit 11 makes transmission end 111 and receiving terminal 112 switch to power supply state, and the second R-T unit 12 also makes transmission end 121 and receiving terminal 122 switch to power supply state.
And, in this example, this transmission end 111,121 and receiving terminal 112,122 Switching power change order can arrange arbitrarily.

When the external command that receives required the first R-T unit 11 to switch to power down mode, the first R-T unit 11 made transmission end 111 and receiving terminal 112 all switch to power down mode.Then, the second R-T unit 12 knows that by monitoring interface 25 the first R-T unit 11 is in power down mode, and makes transmission end 121 and receiving terminal 122 switch to power down mode.
In like manner, when the external command that receives required the first R-T unit 11 to switch to power supply state, all power supply statuss of the first R-T unit 11 and the second R-T unit 12 all switched to power supply state.Wherein, whether the power supply status how the second R-T unit 12 switches transmission end 121 and receiving terminal 122 also can be to have message to import into and decide according to receiving terminal 122, might not need by monitoring interface 25.
Example two: see also Fig. 4, at initial time, all power supply statuss are all power supply state.
When the external command that receives required the second R-T unit 12 to switch to power down mode, the second R-T unit 12 made transmission end 121 and receiving terminal 122 all switch to power down mode.Then, the first R-T unit 11 knows that by monitoring interface 25 the second R-T unit 12 is in power down mode, and makes transmission end 111 and receiving terminal 112 switch to power down mode.
In like manner, when the external command that receives required the second R-T unit 12 to switch to power supply state, all power supply statuss of the second R-T unit 12 and the first R-T unit 11 all switched to power supply state.And also can omit monitoring interface 25, and whether be had message to import into to decide the power supply status of transmission end 111 and receiving terminal 112 by the first R-T unit 11 according to receiving terminal 112.
But no matter communication device 1～4 is in any pattern, application example should not be subject to above-mentioned the announcement.And power down mode can refer to powered-down, can refer to that also power consumption is far below power supply state, for example: be 1/10 power of power supply state.Wherein, for the receiving terminal 122 of the second R-T unit 12, power down mode being set as low-power, whether have message import, to wake at any time (wake-up) second R-T unit 12 up if can continue to observe.In like manner, for the receiving terminal 112 and leading-in end 113 of the first R-T unit 11, power down mode being set as low-power, whether have message import, to wake at any time the first R-T unit 11 up if can continue to observe.
