Exclusive equipment needs are held to be configured, monitored, maintenance and upgrade according to the case where local side apparatus.DSL international standard ITU
G.992.1 it provides, in the state that DSL subscriber end is in power-off, DSL subscriber end must generate and transmit power-off signal to DSL
Local side apparatus.
The local side apparatus and ustomer premises access equipment of DSL system have respective power supply module at present, meeting one after DSL port activation
Directly it is in live line work state.Its course of work is as follows:
The data connection port of local side is in running order, waits user terminal access；
It is powered on after user terminal access；
The data connection port and user terminal of local side carry out normal communication after parameter negotiation；
User terminal power-off；
Local side waits user terminal to access again, at this point, the data connection port of local side is in live line work state.
The above-mentioned course of work is it is found that no matter whether user terminal is in connection state, and the data connection port of local side is all always
In live line work state.Will not be online for a long time in view of most of user, so this long-term electriferous state of local side can be made
At huge energy waste.
Unfortunately, DSL subscriber end in the event of a power failure, and can not be transported the submitting of power-off signal.Thus, it passes
Energy-storage units, such as capacitor technically can be all arranged in system in DSL subscriber end.So that DSL subscriber end is when power is off by capacitor
Energy can act on last power-off signal output.But due to the multiple groups DC operating voltage for generating DSL subscriber end
All DC to DC converters all can consume its capacitive electric energy simultaneously when DSL subscriber end powers off.Therefore DSL subscriber end is simultaneously
Power-off signal can be issued after cannot effectively ensuring power operation each time.

Fig. 2 is power-on and power-off communication apparatus structural schematic diagram of the invention.
Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the present invention:
As shown in Figure 1, a kind of DSL power-on and power-off communication means of the present invention includes two kinds of forms of ADSL or VDSL
After being powered up, power storage got up with the energy storage device that capacitor is main energy storage unit spare at DSL subscriber end.Storage
Energy device plays main power supply function to main control MCU and signal amplifier respectively by two-way current limiter.Main control MCU amplifies signal
Device output powers on trigger signal, and signal amplifier, which will receive, to be powered on trigger signal and be amplified and output to DSL local side.DSL local side
Power-on and power-off trigger receives the notice local side global controller after powering on trigger signal of DSL subscriber end output, the control of the local side overall situation
Device triggering powers on power supply and powers on to DSL subscriber end.In order to which the voltage and current for powering on it is controlled effectively, when powering on
First by electric current by being exported again to DSL subscriber end after rectifying and voltage-stabilizing.
After when DSL subscriber end, power loss stops working, the electric energy that energy storage device is stored is by the first current limiter to master control
MCU effect, main control MCU export lower electric trigger signal to signal amplifier.Signal amplifier is filled by the second current limiter with energy storage
The electric energy for setting sending is work energy, will receive lower electric trigger signal and be amplified and output to DSL local side.Above and below DSL local side
Electric trigger notifies local side global controller, local side global controller after receiving the lower electric trigger signal that DSL subscriber end exports
Triggering powers on electric under power supply, stopping externally transmission of electricity.
In order to ensure that can have enough electric energy amplifications lower electric trigger signal when each power loss, so by the first current limiter
Maximum rated current is smaller than the maximum rated current of the second current limiter, obtains optimal proportion for the first current limiter most by experiment
Big rated current is the 1/2 of the maximum rated current of the second current limiter.
As shown in Fig. 2, a kind of DSL or more electric installation of the present invention, includes DSL subscriber end and DSL local side.It is described
DSL subscriber end cover ADSL user terminal and VDSL user terminal, DSL local side covers ADSL local side and VDSL local side.
DSL subscriber end includes the energy storage device with capacitor for main power storaging unit, and energy storage device passes through the first limit
Stream device and the second current limiter are separately connected main control MCU and signal amplifier.The power-on and power-off trigger signal output end of main control MCU connects
The power-on and power-off trigger signal input terminal of signal amplifier, signal amplifier pass through wideband connection DSL local side.
DSL local side includes for the rectifying pressurizer for powering on electric power outputting current rectifying and voltage-stabilizing, rectifying pressurizer to be set
It sets and is powering between power supply and DSL client.For receiving the power-on and power-off trigger for powering on trigger signal and lower electric trigger signal,
The signal input part of the signal output end connection local side global controller of power-on and power-off trigger, the triggering control of local side global controller
Output end connection processed powers on the triggering control signal of power supply.
It closes the most 1/2 that the maximum rated current of first current limiter is set as the maximum rated current of the second current limiter
It is suitable.Above-mentioned the first current limiter and the second current limiter plays control energy storage device electric current output, avoids the too fast consumption of electric energy, guarantees
Power-off each time can effectively amplify lower electric trigger signal.
Since lower electric trigger signal can be issued when DSL client powers off each time to DSL local side, so DSL local side
Datalink Interface off-position can be in DSL client off-line.Standby power consumption is avoided, it is invalid to greatly reduce
Energy consumption output.
For those skilled in the art, it can make other each according to the above description of the technical scheme and ideas
Kind is corresponding to be changed and deforms, and all these change and deform the protection model that all should belong to the claims in the present invention
Within enclosing.
