Description
[technical field]
The utility model relates to a kind of communicating terminal connecting system, mainly uses on the cable transmission line of ADSL.
[background technology]
Existing communicating terminal connecting system generally is directly to connect adsl cable to user terminal by telecommunications room, is subjected to signal attenuation and various interference effect, and transmission range is very limited.Through certain improvement, can between telecommunications room and user side, add far-end unit, this far-end unit is powered by telecommunications room, is subjected to the restriction of power supply distance, and therefore the transmission range that can prolong is still limited, and the speech channel signal transmission quality is also had certain influence.
Therefore, provide the ADSL repeater that a kind of Distance Transmission that extends, equipment are simple, cost is lower, transmission quality is good real for necessary.
[summary of the invention]
The purpose of this utility model is to provide a kind of Distance Transmission that extends, equipment is simple, cost is lower, transmission quality is good ADSL repeater.
For realizing the utility model purpose, provide following technical scheme:
The utility model patent is from the ADSL repeater of user side power taking, and it comprises the far-end unit that is connected between telecommunications room and the user side, and this user side comprises user terminal and directly connect the user side unit of user terminal that the user side unit powers to far-end unit.
The user side unit provides dc voltage to far-end unit, on with a pair of line, transmit ADSL and telephone path signal simultaneously, promptly the Remote Power Supply between the far-end unit of this system and the user side unit, ADSL signal, analog way transmit on to trunk line same, and the telecommunications room of this system and the ADSL signal between the far-end unit, analog way transmit on to trunk line same.This system realizes a kind of application of the transmission range growth of ADSL.
This user side comprises power circuit, control circuit, POTS and ADSL coupling circuit, circuit both positive and negative polarity testing circuit.
Specifically, the major function of power circuit is to obtain power supply from user's family AC220V civil power, by the conversion of Switching Power Supply, exports the various voltages that need then, the control circuit that low pressure is supplied with user's end plate uses, the confession far away that high-pressure section is supplied with the user and given far-end; Control circuit mainly is the detection of carrying out off hook state and hook state, and handles according to the exchange that the result who detects and far-end carry out information.
When system cut-off, user side leads directly to speech channel and reaches on user's the telephone set, and far-end does not need to pull down, and system still keeps original function.
The contrast prior art the utlity model has following advantage:
The utility model from the ADSL repeater of user side power taking when adding far-end unit, at user side the user side unit is set, power to far-end unit, and control Remote Power Supply, ADSL signal, analog way transmit on to trunk line same, this is used and allows telecom operators to save a large amount of costs when realizing extra long distance ADSL, the equipment network that extends transmission range greatly and do not change machine room connects and does not increase equipment at machine room, and has guaranteed the telephone path signal transmission quality.
[description of drawings]
Fig. 1 is the general illustration of the utility model from the ADSL repeater of user side power taking;
Fig. 2 is a remote principle structured flowchart of the present utility model;
Fig. 3 is a user side theory structure block diagram of the present utility model;
[embodiment]
See also Fig. 1, the utility model comprises the far-end unit (being placed on the centre of user family to office side) that is connected between telecommunications room and the user side, specifically can increase a far-end unit in place from user side 0-3 kilometer, after the ADSL signal amplifies by far-end unit, be connected to office side's machine room of 1-4 kilometer.This user side comprises user terminal and directly connects the user side unit (being placed in the user family) of user terminal.
Wherein far-end unit is meant and is placed on telecommunications room to the middle equipment of user terminal, also can become far-end simultaneously.The user side unit is meant the equipment near user terminal, can be understood as the equipment that is placed in the user family, or is placed on the equipment in the office department, or the equipment in the close user family etc., also can become user side simultaneously.
The user side unit provides dc voltage to far-end unit, the power supply of user side unit input 220VAC, at user side voltage transitions is become the power supply (calling Remote Power Supply in the following text) that uses for far-end unit, Remote Power Supply+ADSL+POTS lumps together, and outputs to then on the trunk line up to far-end unit.On with a pair of line, transmit ADSL and telephone path signal simultaneously, promptly the Remote Power Supply between the far-end unit of this system and the user side unit, ADSL signal, analog way transmit on to trunk line same, and the telecommunications room of this system and the ADSL signal between the far-end unit, analog way transmit on to trunk line same.
This system realizes a kind of application of the transmission range growth of ADSL, the ADSL modem that is equivalent to the super lengthening distance formed by user side and far-end, can need not additionally take on the basis of telecommunication line resource, the distance of ADSL is extended to 4-7Km, and continue to keep original POTS and ADSL business and service quality.
See also Fig. 2, the remote principle structured flowchart, when system did not have power supply, system was directly connected to the user place.When system switch send-add the power supply of a DC110V on the feed line of 48V after, the power supply of far-end unit begins to start, by the time positive postpartum of 5V voltage of power supply, system automatically the switch limit-the 48V feed disconnects, thereby on the bell signal and the power transmission sequence that is capacitively coupled to 110V of telephone path signal from switch by 2.2u.
After if user side detects off-hook, user side sends the information far-end, after far-end is received information, starts the simulation off-hook, the exhalation that can just produce of system like this.
If system is incoming call, bell signal sees through far-end, be synthesized on the user side-feed of 48V on.Far-end sends two DTMF data to user side, and transmitting needs minimum 160mS, and far-end is judged needs 20mS, altogether the shortest 180mS of time-delay.
The ADSL signal need carry out processing and amplifying at far-end, and the ADSL signal of separating carries out independent amplification.Voice signal is directly coupled on the circuit.Guarantee transmission quality.
When user side cut off the power supply, far-end led directly to speech channel and reaches on user's the telephone set.
See also Fig. 3, user side theory structure block diagram.User side mainly is made up of the circuit of several sections such as power circuit, control circuit, POTS and ADSL coupling circuit, circuit both positive and negative polarity testing circuit.The major function of power circuit is to obtain power supply from user's family AC220V civil power, the conversion by Switching Power Supply then, and the various voltages that output needs, the control circuit that low pressure is supplied with user's end plate uses, the confession far away that high-pressure section is supplied with the user and given far-end; Control circuit mainly is the detection of carrying out off hook state and hook state, and handles according to the exchange that the result who detects and far-end carry out information.
Bell signal by coupling capacitance be directly coupled to-feed of 48V on.
When system cut-off, user side leads directly to speech channel and reaches on user's the telephone set.
The above only is preferred embodiment of the present utility model, and protection range of the present utility model is not limited thereto, and anyly all belongs within the utility model protection range based on the equivalent transformation on the technical solutions of the utility model.
