What is claimed is:

1. A group wiring patching device comprising:
a plurality of wire pair receptacles, each receptacle further comprising at least two contacts each connecting with a conductive wire; and a plurality of testing circuits, each testing circuit coupling between said conductive wires of said contacts of one receptacle and further comprising:
at least one light emitting means coupling with said testing circuit for emitting light when a testing voltage is applied to said testing circuit; and
a filtering means serially coupling with the light emitting means on the testing circuit for diminishing loop back shorting between said contacts when a communication signal being applied to said contacts;
wherein said filtering means further comprises an artificial wire for diminishing low voltage loop back shorting.
2. The group wiring patching device of claim 1, wherein said filtering means further comprises a low-pass filter which can filter signals having a frequency higher than 200 Hz.
3. The group wiring patching device of claim 1, wherein said artificial wire is a resistor having resistance greater than 400 ohm.
4. The group wiring patching device of claim 1, wherein said group wiring patching device further comprises a panel and a circuit board for furnishing said testing circuit, said light emitting means and said filtering means; wherein said panel supports said wire pair receptacles and the circuit board; wherein at least part of light emitted by said light emitting means is exposed out of a front surface of the panel.

5. The group wiring patching device of claim 1, wherein said light emitting means comprises two individual LED members connected in parallel but in reverse polarities.

6. A group wiring patching system for wire pair identification comprising: a tester for supplying a testing voltage;
a group wiring patching device comprising a plurality of wire pair receptacles, each wire pair receptacle having at least two contacts and being coupled with at least one light emitting means and a filtering means, the light emitting means being coupled between said contacts, said filtering means being serially coupled with the light emitting means between said contacts for eliminating loop back shorting between said contacts when communication signals are applied to said contacts;
at least one local receptacle being located remote from said group wiring patching device, said local receptacles having at least two contacts; and
means for electrically coupling said contacts of said local receptacles with said contacts of said wire pair receptacles so as to define wire pairs therebetween;
wherein, said tester supplying said testing voltage to one of the local receptacles causing the light emitting means of the wire pair receptacle which is coupled with that local receptacle to light so as to identify the corresponding wire pair between the local receptacles and the wire pair receptacles;
wherein said filtering means further comprises an artificial wire for diminishing low voltage loop back shorting.
7. The group wiring patching system of claim 6, wherein said light emitting means comprises two individual LED members connected in parallel but in reverse polarities.
8. The group wiring patching system of claim 6, wherein the tester further comprises:
an output ;
a testing voltage supplier further including a DC battery for properly providing said testing voltage;

a cable stability/characteristics testing module for providing at least one function of cable stability/characteristics tests;
an input interface for receiving operating commands of the tester;
a controller connecting with said output, testing voltage supplier, cable stability/characteristics testing module and input interface; and a display panel for displaying functioning status of the tester;
wherein, by operating the input interface, the controller switches the connections between the cable stability/characteristics testing module and testing voltage supplier so as to allow either one of these two to send signals to the output.
9. A method for identifying wire pairs in a wiring system, said wiring system comprising a plurality of first receptacles and a plurality of second receptacles which are located remote from said first receptacles, each of the second receptacles being connected with only one corresponding first receptacle to form a wire pair therebetween; each of said first receptacle further comprising:
at least two contacts;
at least one light emitting means coupled between the contacts; and a filtering means serially coupling with the light emitting means between said contacts for eliminating loop back shorting between said contacts when communication signals are applied to said contacts;
wherein said filtering means further comprises a low-pass filter which can filter signals having a frequency higher than 200 Hz; the method comprising the step of:
applying a testing voltage to one of the second receptacles to cause the light emitting means of the corresponding first receptacle to light such that the wire pair therebetween is identified;
wherein, when communication signals are applied to said contacts of the first receptacles, said filtering means eliminates loop back shorting between said contacts such that normal communication operations between said first and second receptacles are not influenced even when the light emitting means are still coupled between said contacts.

10. The method of claim 9, wherein said filtering means further comprises an artificial wire for diminishing low voltage loop back shorting.
11. The method of claim 9, wherein said light emitting means comprises two individual LED members connected in parallel but in reverse polarities.
