Description

584733 V. Description of the invention (1) Field of the invention: The present invention relates to a group wiring device, system and method capable of identifying wire pairs, especially an improved group wiring device such as a wiring panel, which can be matched with a voltage Provider is used for pair identification. BACKGROUND OF THE INVENTION In today's world where lines are used for signal transmission, it is often necessary to identify pairs of different lines or circuits connected to two different locations. Please refer to Figure 1. For example, for a typical communication system, such as: network service providing system (ISP), local area network system (LAN), wide area network system (WAN), metro area system (MAN), enterprise Intranet systems (ranet), Internet systems (Internet), telephone work centers, etc., usually involve hundreds or even thousands of end users in different regional locations sharing the same server system 10 Services provided. Some users 丨 丨 may be connected to the servo system via the Internet 11 丨 through the modem 11 2. Some users J 2 may use a remote area server 21 21 to connect to the servo system 10 ° Other users 13 may use a hub 1 3 1 (Hub) located on different floors of the same building The servo system 1 〇. Some users 14 may use the network cable socket 141 (Jack) located near their seat or work table to connect to the servo system 10. In addition, some users 15 will use the wireless network device 151 and wireless hub 152 to use the servo system 10 °. Sometimes it is necessary to connect another servo system 丨 〇a to this servo system 10. And all the above connection work needs to be used more or less

584733 V. Description of the invention (2) The so-called "Wires" or "CabUs" to connect to the servo system 10. Therefore, the line system (w 丨 r 丨 ng System) has become a subject worthy of attention and consideration. In this line system, thousands of lines from all directions will be concentrated and connected to a distribution frame 2 (Distribution Frame) before being connected to the servo system 10, such as a patch panel stack (Patch P ^). nel Stack). Obviously, for this huge line system, a, how to effectively manage these many lines is extremely important. For example, how j = which socket 21 1 on the other panel 21 is connected to a remote location. The traditional method for wire pair identification requires two workers. Among them, the workers are kept in the position of the panel stack (the distribution frame 20). The two workers are the remote end-users who are maneuvering and moving. The work path at the remote end user location. : When a test signal is transmitted to the position, the staff at the stacking position of the hub panel uses one by one: :::: sequentially inserted into each of the sockets on the stack of the hub panel to drive and "this :: device After receiving the aforementioned test signal, it will be identified later. This time ^ is identified and numbered for identification. ▲ A u: Repeat the break until all the pairs are very wasteful; and there are very m kinds of traditional pairs. The identification method is not only a knife but also very time-consuming. In a typical large-scale line system, 584733 V. Description of the invention (3) Sometimes it takes days or even weeks to identify. US Patent US. PAT. NO. 5847557 The case once revealed a unified wire pair identification method. Before the wire pair identification was started, each wire on the wire stack = board stacking (distribution frame) was inserted. Insert one; A light-emitting diode (LED). A test voltage is provided at the end user's position. A finger on the hub and a sibling line connected to the remote end user's position will plug in the test voltage. And make it a light emitting diode Illuminated. U-specific wire pairs can be identified. Since the workers at the hub panel stacking rack no longer need to scan the female and sockets on the hub panel stack one by one, time and labor costs can be reduced. Green batch However, the method of wire pair identification disclosed in US Patent No. ρατ · no. 584755 is still lacking. For example, it requires workers to stack all of the hub panels (distribution frames) before performing wire pair identification. An indicator plug (possibly thousands) is inserted into each socket. Then, after all the pair identification work is completed, all indicator plugs must be removed—from the hub panel stack (distribution frame). This remains Is a time-consuming and annoying task. And 'for the technology disclosed in the US Patent "· ρΑΤ · NO．5847557, we cannot directly build a light-emitting diode (LED) built-in (Built-in) in In the socket of the stacking panel (distribution frame). This is because the light emitting diode (LEI) circuit will cause a short circuit between two contacts in the socket. Once the hub panel is stacked under normal operation ’, for example, for transmitting communication signals (communicatioI1 Signals), the light emitting diode (LED) circuit will cause a“ short loop

The filtering device 452 includes a low-pass filter 4521 and an artificial wire 4522 (Artificial ffire). Preferably, the low-pass filter 452m can only allow signals with a frequency below 200 Hz to pass. Therefore, almost all communication signals, including telephone signals and computer network signals, will be filtered by this low-pass filter 4521, and only some low-frequency signals such as the AC voltage signal or other tests The signal can pass. The artificial wire 4522 is used to simulate a considerable length of line (or cable). Therefore, when the stability or other electrical characteristics of some cables are tested, the two contacts 4 31, 4 3 2 will not It is considered a "short circuit". The principle of this artificial wire 4522 is to provide a sufficiently large resistance value, so when a low-frequency test signal is issued by a cable stability (or electrical property) tester, the test circuit 45 (that is, The signal of the light-emitting device 451 and the filtering device 4 52) will be very weak, so that the cable stability (or electrical characteristics) tester "thinks" that there is no such test at the two contacts 4 3 1, 4 3 2 The presence of circuit 45.

Description of the invention (9) Includes two sets of independent light-emitting diode elements 4511, 4512 (LED), the two of which are connected in parallel but have opposite polarities. In this way, regardless of the direction of the DC test voltage transmitted by the cable tester 60, one of the light-emitting diode elements 4511 and 4512 will light up. In addition, the light-emitting colors of the two light-emitting diode pieces 4511 and 45 12 may be different. Therefore, by identifying the color of the light-emitting diodes, it is possible to further determine whether the two wires 51 and 52 are reversely connected when performing the wire pair identification. . In addition, when an AC voltage or other low-frequency signals from the aforementioned cable stability (or electrical property) tester are applied to the two contacts 431, 432, the two light-emitting diode elements 4511, 4512 It will flash alternately to identify its state (of course, only when the voltage is large enough to drive the light-emitting diode elements 4511, 4512 to light).
