Description

<Desc/Clms Page number 1>
Title : Improvements in Cable Tracing DESCRIPTION This invention concerns a device for tracing cables, in particular for tracing patch cords used in conjunction with a patch panel.
A patch panel is an assembly of pin locations and ports, which enables cable from different rooms to be connected to each other, thereby forming a local network. Patch panels are commonly used in telecommunications systems such as telephone networks in, for example, offices, where a number of telephones having different extension numbers are to be connected to various telephone sockets in the office. It is usually mounted on a rack or a wall bracket, and is connected to a working telecommunications circuit such as an ISDN line, an exchange line, an analogue extension or a digital extension, which controls the telephone lines and extension numbers.
The ports are located on one face of the patch panel, and the pin locations are located on the reverse face. Each pin location is connected to the corresponding port on the reverse face of the patch panel.
A jumper cable called a patch cord is generally used in conjunction with the patch panel, and in use, the ends of the patch cord are inserted into the ports of the patch panel to cross connect telephones with sockets wired to the patch panel.
An example of an application for a patch panel is in an office, which has a telephone in each room thereof. Each telephone in the office has to have a particular extension number assigned to it, to enable calls to be
<Desc/Clms Page number 2>
diverted from a central telephone line, by a receptionist for example, to that particular telephone. Say, for example, a telephone is plugged into a telephone socket in a particular room; that socket is connected by a fixed cable or the like to a pin location on one side (hereinafter called the"socket side"), generally the right hand side, of a patch panel. Each of the sockets in the other rooms of the office are connected to other pin locations on the socket side of the patch panel.
The pin locations on the other side (hereinafter called the"extension side"), generally the left hand side, of the patch panel are connected to the working telecommunications circuit. For example, one particular pin location on the extension side of the patch panel is assigned extension number 230 by the telecommunications circuit, another is assigned extension number 231, and so on.
A patch cord is then used to assign a particular extension number to a particular telephone socket. For example, if telephone socket A in the office manager's room is to be assigned extension number 230, then one end of a patch cord is plugged into the port on the socket side of the patch panel, which corresponds to the pin location connected to the socket in room A, and the other end of the patch cord is plugged into the port on the extension side of the patch panel, which corresponds to the pin location for extension number 230. In this way, when a telephone call comes in for the person answering the telephone plugged into socket A in the office manager's room, then the operator diverts it to extension 230, and that person duly receives the call.
<Desc/Clms Page number 3>
Accordingly, if a person moves to a different room, but wants to keep their extension number, then by moving the patch cord from the port corresponding to the pin location connected to socket A, to the port for, say, socket B in the library, that person can keep their extension number.
Naturally, if the telecommunications system in the office comprises a lot of telephone sockets, then a patch panel having a large number of ports and pin locations has to be used, requiring a large number of patch cords to connect socket ports and extension ports together. Accordingly, it can often be difficult, if not impossible, to trace which ports each end of a particular patch cord is plugged into, without the use of some form of tracing device.
It is known to provide a one-piece device, which allows the user to trace all of the patch cords at once. This device comprises a fascia, which plugs into all of the ports of the patch panel. The patch cords are then plugged into the fascia as opposed to the patch panel itself. However, a disadvantage is that, using this device, all of the patch cords must be traced, resulting in a rather bulky addition to a patch panel, which also must be plugged into the patch panel prior to any patch cords being plugged into the patch panel. Furthermore, the device does not accommodate the varying sizes of patch panel, which are in existence.
Alternatively, it is known to use a tracing device, which may be plugged into a patch cord, in situ on a patch panel, the patch cord being specially adapted for the purpose by having an extra receptacle thereon.
It is an object of the present invention to provide an improved device for tracing patch cords on a patch panel.
<Desc/Clms Page number 4>
In accordance with the present invention, there is provided a tracing device connectable to each end of a patch cord, to be used in conjunction with a patch panel, the panel having a plurality of engageable members thereon, at least one of which is connectable to a working telecommunications circuit, and the patch cord having a complimentary engageable member at each end thereof, wherein the tracing device comprises at least one engageable member, at least one complimentary engageable member, a switching means and an indicating means, whereby the complimentary engageable member at the end of the patch cord is insertable into the engageable member of the tracing device, and the complimentary engageable member of the device is insertable into the engageable member of the patch panel, the indicating means on both tracing devices being activated when the switch on either of the tracing devices is closed.
In a preferred embodiment of the invention, the panel has a plurality of female members thereon, the patch cord has a male member at each end thereof, and the tracing device comprises at least one male member and at least one female member.
More preferably still, the tracing device comprises one male member and one female member connected back to back.
Preferably, the indicating means is a visual indicating means, more preferably still a light emitting diode.
The switching means is preferably a slide switch, but any other suitable switching means may be used, such as a push-to-make switch.
<Desc/Clms Page number 5>
An advantage of the tracing adapter of the present invention is that the user can attach the tracing device to their existing patch panels and patch cords without using modified patch cords or patch panels. The female member of the tracing device is preferably a standard female RJ45 connector of the type to fit a standard male RJ45 connector typically found on the ends of patch cords, and the male member of the tracing device is preferably a standard male RJ45 connector of the type to fit a standard female RJ45 connector, which typically form the ports on patch panels.
Alternatively, the female member of the tracing device is a standard female RJ 11 connector of the type to fit a standard male RJ 11 connector, which may also be found on the ends of patch cords, and the male member of the tracing device may be a standard male RJ 11 connector of the type to fit a standard female RJ11 connector, which may also typically form the ports on patch panels.
The invention will now be further described, by way of example only, with reference to the accompanying drawings in which :- Figure 1 shows a side view of a tracing device in situ, in accordance with the present invention; Figure 2 shows a front view of a patch panel.
Figure 3 is a circuit diagram showing a tracing device in accordance with the present invention.
As can be seen from Figures 1 and 2, the device 1 comprises a female member 2 and a male member 3, an indicating means 4 in the form of a light emitting diode, and a switching means 5. The male member 3 of the device 1 is insertable into a female member 6 of a patch panel 7, and the male
<Desc/Clms Page number 6>
member 8 at one end of a patch cord 9 is insertable into the female member 2 of the device 1. The other end of the patch cord 9 is similarly insertable into another female member 10 of a patch panel 7. The female member 10 of the patch panel 7 is connectable to a working telecommunications circuit 11, such as an ISDN line, an exchange line, an analogue extension, or a digital extension. In this way, the device takes power from the working telecommunications circuit 11 to activate the indicating means 4, and accordingly, the device 1 does not require a separate power supply to operate. The female members of the patch panel 7 are each connectable to a telephone socket 12, and in this way, if the extension number of a particular socket is to be changed, then the patch cord 9 needs to be moved to the relevant female member. It is at this point that difficulties may arise in locating the other end of the patch cord 9, and it is therefore at this point that the device 1 of the invention, may be used to locate the other end of the patch cord 9, simply by activating a switching means 5, on the device 1, at either end of the patch cord 9, thereby illuminating the indicating means 4 at both ends of the patch cord 9 for tracing purposes.
As can be seen from Figure 3 of the drawings, the circuit involved with the device 1 works on the principle that, if a switching means 5 on the device 1 at either end of the patch cord 9 is operated, both of the indicating means 4a and 4b are activated. In this way, both ends of the patch cord 9 may be traced, without interrupting the working circuit.
