Abstract
The invention discloses a DSL power-up and power-down communication method and equipment thereof. Electric energy stored in capacitors in normal working is used for a master control MCU and a signal amplifier. A local side is timely notified to perform power-down of a corresponding port when power outage occurs at a user side each time. The advantages of the DSL power-up and power-down communication method and the equipment thereof are that current limiting control of electric energy of the capacitors can be performed and other DC elements cannot rapidly use up electric energy of the capacitors so that the user side is ensured to emit a power-down trigger signal to the local side when power outage occurs on the user side each time. The local side receives the power-down trigger signal and then can disconnect the original conducted port so that large amount of energy source can be saved.

The local side apparatus of current DSL system and ustomer premises access equipment have respective supply module, can be in live line work state after DSL port activation always.Its course of work is as follows:
The data connection port of local side is in running order, waits for user side access;
Power on after user side access;
The data connection port of local side and user side carry out proper communication after parameter negotiation;
User side power-off;
Local side waits for that user side accesses again, and now, the data connection port of local side is in live line work state.
The above-mentioned course of work is known, and no matter whether user side is in connection state, and the data connection port of local side is in live line work state all always.In view of most of user can not be online for a long time, so this long-term electriferous state of local side can cause huge energy waste.
Unfortunately, DSL subscriber's end in the event of a power failure, and cannot transport sending power-off signal.Thus, conventional art all can arrange energy-storage units, such as electric capacity in DSL subscriber's end.So that the energy of electric capacity can be acted on last power-off signal and export by DSL subscriber's end when power-off.But because all DC-DC transducers of the many groups DC operating voltage held for generation of DSL subscriber all can consume its capacitive electric energy when DSL subscriber holds power-off simultaneously.Therefore DSL subscriber can send power-off signal after holding the power operation can not effectively guaranteed each time.

Embodiment
Below, by reference to the accompanying drawings and embodiment, the present invention is described further:
As shown in Figure 1, a kind of DSL power-on and power-off communication means of the present invention is that the DSL subscriber comprising ADSL or VDSL two kinds of forms holds after being powered up, is that power storage is got up for subsequent use by the energy storage device of main energetic storage element with electric capacity.Energy storage device plays main power supply function to main control MCU and signal amplifier respectively by two-way flow restricter.Main control MCU exports to signal amplifier the triggering signal that powers on, and signal amplifier will receive the triggering signal that powers on and amplifies and output to DSL local side.The power-on and power-off trigger of DSL local side receives after DSL subscriber holds the triggering signal that powers on of output and notifies local side global controller, and local side global controller triggers the power supply that powers on and powers on to DSL subscriber's end.The voltage and current powered on to make it is controlled effectively, when powering on first by electric current by holding output to DSL subscriber again after rectifying and voltage-stabilizing.
After DSL subscriber holds dead electricity to quit work, the electric energy that energy storage device is stored is by the first flow restricter to main control MCU effect, and main control MCU exports lower electric triggering signal to signal amplifier.Signal amplifier is by the second flow restricter, and the electric energy sent with energy storage device is work energy, will receive lower electric triggering signal and amplifies and output to DSL local side.The power-on and power-off trigger of DSL local side receives after DSL subscriber holds the lower electric triggering signal of output and notifies local side global controller, and local side global controller is electric under triggering the power supply that powers on, and stops externally transmitting electricity.
Lower electric triggering signal is amplified in order to ensure enough electric energy can be had during each dead electricity, so the maximum rated current of the first flow restricter is less than the maximum rated current of the second flow restricter, show that optimal proportion be the maximum rated current of the first flow restricter is 1/2 of the maximum rated current of the second flow restricter by experiment.
As shown in Figure 2, a kind of DSL power-on and power-off device of the present invention, includes DSL subscriber's end and DSL local side.Described DSL subscriber's end covers ADSL user side and VDSL user side, and DSL local side covers ADSL local side and VDSL local side.
It is the energy storage device of main power storaging unit that DSL subscriber's end includes with electric capacity, and energy storage device is connected main control MCU and signal amplifier by the first flow restricter respectively with the second flow restricter.The power-on and power-off triggering signal input of the power-on and power-off triggering signal output connection signal amplifier of main control MCU, signal amplifier is by wideband connection DSL local side.
DSL local side includes for the rectifying pressurizer to the electric power outputting current rectifying and voltage-stabilizing that powers on, and rectifying pressurizer is arranged on and powers between power supply and DSL client.For receiving the power-on and power-off trigger of power on triggering signal and lower electric triggering signal, the signal output part of power-on and power-off trigger connects the signal input part of local side global controller, and the trigging control output of local side global controller connects the trigging control input of the power supply that powers on.
The maximum rated current of the first flow restricter is set as 1/2 of the maximum rated current of the second flow restricter is the most suitable.The first above-mentioned flow restricter and the second flow restricter play and control energy storage device electric current and export, and avoid the too fast consumption of electric energy, ensure that power-off each time effectively can amplify lower electric triggering signal.
Due to lower electric triggering signal can be sent to DSL local side during DSL client power-off each time, so the Datalink Interface of DSL local side can be in off-position when DSL client off-line.Avoid standby power consumption, greatly reduce invalid energy consumption and export.
For a person skilled in the art, according to technical scheme described above and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection range of the claims in the present invention.
