Abstract
The utility model relates to a universal-type ADSL line tester, comprising an ADSLMODEM circuit with a signal indication light emitting diode, a network interface, a telephone line interface, a USB power interface, further comprising a shell with a battery clamp and a power switch. The utility model can supply power directly using a built-in dry battery without external power source, has the advantages of strong pertinence, simple structure, small volume, light weight, convenient carrying and operation and quite low price, and is easy to be allocated for every maintainer.
Description
Technical field
The utility model relates to a kind of ADSL (being also referred to as ADSL (Asymmetric Digital Subscriber Line)) line tester, particularly a kind of volume is little, cheap, portably use popular easily adsl line tester, belongs to network communication field.
Background technology
Use the broadband access network technology in a large number among the domestic numerous fixed telephone subscribers at present, this technology just can make computer utilize telephone wire to realize the high-speed wideband online by existing telephone wire through ADSL (ADSL (Asymmetric Digital Subscriber Line)) MODEM (modulator-demodulator), have easy to use, advantage such as cheap, ADSL MODEM can match in excellence or beauty with the fiber broadband online at aspects such as transmission rates at present, used in a large number by computer user, the broadband user's 75% all use ADSL MODEM according to statistics.
Each telecom operation at present has 8,000 ten thousand ADSL users, is the broadband main users of each telecom operators.How having served these ADSL users is each telecom operators' most important thing.Because the ADSL technology is to utilize existing telephone cable to carry out transfer of data, the telephone wire of a lot of telecommunications companies is aging, burn into or loose contact, so ADSL broadband user's access fault is on the high side, each telecom operators has descended very big energy to serve these ADSL users for this reason.
The transmission characteristic of ADSL access technology as shown in Figure 1, one road ADSL subscriber signal is transferred to user ADSL MODEM must pass through test desk, cross-connecting box, junction box, user family's line interface, corresponds respectively to A among Fig. 1, C, E, G 4 points.So when the DSLAM that can not receive telecommunications room in the user family (ADSL switch) signal, the ADSL signal might break down at ADSL switch to test desk, test desk to cross-connecting box, cross-connecting box to junction box, junction box to four sections circuits such as user family's line interface, in order to detect the ADSL signal, need carry out signal measurement with instrument piecemeal at above-mentioned four sections, so that remove barriers fast.The ADSL test instrumentation all is professional instrument at present, test function is complete, but its complex structure, volume is big, operate loaded down with trivial details, price up to 5000 yuan～100,000 yuan, can't spread to one of attendant's staff, also need external 220V ac power supply simultaneously, use very inconvenient, especially all the more so when outdoor cross-connecting box and junction box handling failure.
The utility model content
Order of the present utility model is in order to overcome the weak point of above-mentioned tester, to provide a kind of volume of built-in power little, in light weight, carries easy to operately, cheap, is easy to be equipped with the popular adsl line tester that uses to every attendant.
Popular adsl line tester of the present utility model, comprise the ADSL MODEM circuit, netting twine interface, telephone line interface, the USB power interface that are provided with signal indication light-emitting diode, be provided with the housing and the mains switch of battery folder, described mains switch is contained in the right edge of housing, battery folder is arranged on lower part of frame, ADSL MODEM circuit is contained in housing top, netting twine interface, telephone line interface and USB power interface are contained in the upper side edge of housing, indicate the case panel of light-emitting diode correspondence position to be provided with loophole with signal.
For the ease of selecting working power, 4 joint dry cells are housed in the described battery folder, the positive pole of dry cell is connected through the positive pole of mains switch with the USB power interface, the negative pole of dry cell is connected with the negative pole of USB power interface, and the both positive and negative polarity of USB power interface is connected with the positive-negative power end of ADSLMODEM circuit respectively.
Anti-in order to prevent battery dress, can between the positive pole of dry cell and mains switch, be serially connected with a step-down protection diode.
Popular adsl line tester of the present utility model, owing to be provided with USB power interface and battery folder simultaneously, under the situation of no external power supply condition, also can use built-in dry cell directly to power, pointed strong, simple in structure, volume is little, and is in light weight, carries easy to operate, advantages such as price is cheap especially are easy to be equipped with and generally use for every attendant.
