Abstract

The socket with internal wire and outside wire is set at one end of the cable. The vertical arranged or horizontal arranged plug is set at other end of the cable. The voltage stabilizing diode W1 and W2, light-emitting diode D1 and D2, resistor R is set. The cathode and anode of D1, D2 are parallel connected in reverse phase, one end is connected with the cathode of W1, and the anode is connected with testing outside wire a; the other end is connected with one end of R, other end of R is connected with cathode of W1; the anode of W2 is connected with testing outside wire; the 48v voltage in exchanger is used as the power to drive light-emitting diode D1 and D2.

Description

Adsl line horizontally-arranged, in line multi-thread test cable

Technical field:

The present invention relates to the information network testing equipment, especially the equipment that the ADSL network is tested automatically.

Background technology:

At present domestic adsl line test major part is to rely on universal instrument, 112 systems and handheld instrument, need two people to cooperate and carry out Dual-Ended Loop Test, test event is few, efficient is low, can not carry out diagnostic analysis and fault is qualitative, the location to test result, and can not carry out single-ended batch and fixed time test adsl line.And test result can not be preserved and inquire about easily.When user applies ADSL is professional, be to guarantee user's development, often circuit is not tested open-mindedly immediately, as run into the subscriber's line poor quality, can not carry ADSL when professional, cause that the user is discontented, it is passive that service causes.Along with increasing rapidly of customer volume, operation maintenance work is doubled and redoubled, and relies on the Dual-Ended Loop Test method of service mode and handheld instrument after traditional fault can not adapt to the needs of business development far away.

This purpose is: provide a kind of and can finish the adsl line horizontally-arranged of single end testing, batch testing, fixed time test, in line multi-thread test cable.

Summary of the invention:

Be provided with the socket of interior and exterior lines at an end of cable, be provided with the latch of in line or horizontally-arranged at the other end of cable; Voltage stabilizing didoe W1, W2 are set, light-emitting diode D1, D2, resistance R; With D1, D2 both positive and negative polarity parallel connected in reverse phase, a termination W1 negative pole, positive pole meet test outside line a; Other end connecting resistance R one end, R one termination W2 negative pole, W2 positive pole meet test outside line b; Utilize in the switch-48V voltage is as light-emitting diode D1, D2 pilot lamp power.

Software adopts following steps: the test → initialization test equipment → access test cable → test cable of a circuit of beginning inserts in line or horizontally-arranged → indicator light brightens → controls, and electronic matrix is grabbed outside line, indicator light test → control the electronic matrix that goes out → begin carries out unwrapping wire, indicator light brighten → the finish test of a circuit.

The present invention inserts during very convenient user test, and can indicate contact condition when inserting; During test, can cut off the circuit of exchanger side, finish the line test of high frequency, when after access, not testing again simultaneously, not influence user's normal use.Once can measure crosstalking between many circuits and the circuit, realize single end testing, batch testing, fixed time test,, analyze out of order reason and position immediately after test is finished simultaneously by analysis to test result.

Description of drawings:

Accompanying drawing 1 is an external electric connection layout of the present invention;

Accompanying drawing 2 is latch electrical connection graphs in upright arrangement in the machine room of the present invention;

Accompanying drawing 3 is system of the present invention controlling party block diagrams;

Accompanying drawing 4 is software flow patterns of the present invention.

Execution mode:

Among the figure: 1: for the distributing frame outside line right; 2: latch in upright arrangement; 3: the latch test is outer right; 4: external cable 50PIN plug; 5 matrix external cable 50PIN plugs; 6: electronic matrix; 7: the electronic matrix port; 8: the distributing frame interior lines are right; 9 latches test interior lines are right; 10: internal subscriber cable 50PIN plug; 11: matrix internal subscriber cable 50PIN socket; 12: test cell; 13 latches test outside line a; 14: latch test outside line b; 15: voltage-stabiliser tube; 16: light-emitting diode; 17: resistance; 18: latch test interior lines a '; 19: latch test interior lines b '.

End at cable is provided with the interior and exterior lines socket, is provided with in line or the horizontally-arranged latch at the other end of cable; Voltage stabilizing didoe W1, W2 are set, light-emitting diode D1, D2, resistance R; With D1, D2 both positive and negative polarity parallel connected in reverse phase, a termination W1 negative pole, positive pole meet test outside line a; Other end connecting resistance R one end, R one termination W2 negative pole, W2 positive pole meet test outside line b; Utilize in the switch-48V voltage is as light-emitting diode D1, D2 pilot lamp power.When array or line socket and plug contact when bad ,-48V voltage does not exist, and light-emitting diode does not work, otherwise light-emitting diode is bright.During test, electronic matrix cuts off switch hand hay cutter circuit, and light-emitting diode does not work yet.Add 5V test voltage signal, this moment, electronic matrix interior and exterior lines socket was connected at ordinary times, design by a pair of inlet wire and a pair of outlet, after the interior and exterior lines socket is linked into electronic matrix interior and exterior lines socket, all array or line latch interior and exterior lines are also connected on the cable at ordinary times, when Loop test was carried out on the single line road, electronic matrix can cut off this interior lines to line, and can test outside line this moment by test cell.When interior lines are tested (port of testing ADSL port or switch), electronic matrix can cut off this outside line to line, and can test interior lines this moment by test cell.After test was finished, electronic matrix can recover being connected of interior lines and outside line.
