ADSL Power Supply and Measuring Equipment {DEVICE OF POWER SUPPLY AND MEASURE FOR ADSL}

The present invention relates to an ADSL modem apparatus, and more particularly, to an apparatus capable of supplying power to an ADSL modem and measuring a line state of the ADSL.

In general, an asymmetric digital subscriber line (ADSL) can provide high-speed digital service simultaneously without interfering with analog telephone service on an existing twisted pair copper network. will be.

In other words, the above-described ADSL system is a technology that increases bandwidth to simultaneously transmit multimedia information such as voice, graphics, and video while using an existing telephone line. Therefore, the ADSL system does not incur network installation costs and provides multimedia information to subscribers. This technology is in the spotlight recently.

In particular, it is not necessary to install a new line to operate such an ADSL system, so it is possible to implement the service more economically and faster than using other systems. Additionally, the detailed configuration of the above-described ADSL system is disclosed in Korean Patent Laid-Open Publication No. 99-2306 (Duplicate Network Management Device of Asymmetric Digital Subscriber Line (ADSL) System) and Publication No. 2000-15680 (Improved Asymmetric Digital Subscription). Charity (ADSL) system).

On the other hand, when collecting various information outdoors using the above-described ADSL system or connecting various types of information by connecting a portable computer such as a laptop and an ADSL system, a separate power supply device is required, and in particular, on the ADSL line, Many separate devices are required to measure them.

That is, in the related art, since the measurement equipment is combined and then set in the PC, the PC is rebooted, and the ADSL line is measured, the preparation time and the measurement time are excessive, and the measurement equipment is particularly expensive. Therefore, there is a problem that is inconvenient to carry.

Therefore, an object of the present invention for solving the above problems is to provide a device that can supply power to the ADSL and measure the line state of the ADSL when collecting information by connecting the outdoor or portable computer and the ADSL system have.

Another object of the present invention is to provide a power supply device and a measuring device for the ADSL as a low cost equipment.

Another object of the present invention is to provide an ADSL power supply and a measuring device that can easily check the instability of the line in the case of the opening and failure of the ADSL.

Another object of the present invention is to provide a device capable of supplying power and measuring line conditions regardless of the type of modem.

The present invention according to the first aspect for achieving the above object is a power supply cord for supplying power to all kinds of modems regardless of the type of ADSL modem, and test code for measuring the line status of the ADSL modem Equipped; 5V DC terminal and 12V DC terminal for connecting the jack of the power supply cord, a switch for selecting the power supplied to the modem, and an EXT terminal for supplying power to the modem when a modem having a special power jack is used. The power supply device is configured to supply power to the ADSL modem and measure a line state of the ADSL.

Hereinafter, a detailed description of a preferred embodiment of the present invention will be described with reference to the accompanying drawings. In the following description of the present invention, if it is determined that the detailed description of the related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. In addition, terms to be described later are defined in consideration of functions in the present invention, which may vary according to the intention or custom of a user or a chip designer, and the definitions should be made based on the contents throughout the present specification.

First of all, the concept of the ADSL power supply and measuring device proposed in the present invention is a DC power supply, which can supply power to various ADSL modems that are currently being supplied, and the phase supply is provided by combining the power supply and modem of the present invention. It is to propose a device that can easily check the line status and section in an inappropriate environment.

According to an embodiment of the present invention, the configuration of the ADSL power supply and measurement apparatus proposed above is as shown in FIG. 1. Referring to FIG. 1, a device to be implemented in the present invention includes a power supply device 10 having a DC terminal 12 and 24, a selector switch 14, and an EXT terminal 16, 18, and 20 and an ADSL modem. It consists of a power supply cord 28 for supplying power to the test code 30 for measuring the line state of the ADSL.

The DC terminals 12 and 24 are installed at both sides of the front panel of the power supply 10, and the jacks 28 of the power supply cord 28 are inserted and are divided into 5V and 12V. At this time, the ADSL modem connected to the 5V DC terminal 12 is' Cisco 677 (brand name) ', and the modem connected to the 12V DC terminal 24 is' Acelink (product name) of Samsung' and 'Alcatel of Daewoo ( Brand name) "and" CT-300 (trade name) of temper. "

The selection switch 14 is a switch for selecting a power source according to the type of the ADSL modem, and the selection switch 14 may select 5V and 12V, respectively. The EXT terminals 16, 18, and 20 are modems using special power jacks, mainly ADSL modems produced in modern times, and are generally classified into 12V, 0V, and 5V. The LED 22 is a lamp that is turned on when the jack is inserted into the 12V DC terminal 24 or the EXT terminals 16, 18, and 20, and the charging terminal 26 supplies a constant voltage to the power supply device 10 described above. It is a terminal to charge.

On the other hand, Figure 4 is a circuit diagram showing the internal configuration of the power supply device 10 described above, the battery 32, 34 is charged with the power supplied from the charging terminal 26, the capacitor 36 is a power stabilization capacitor Always output 5V. Also, the stabilization circuits 38a and 38b always output a constant voltage. Preferably, the voltage of 6V or more is reduced to 5V and the voltage is stabilized and output.

Hereinafter, a method of using the power supply device 10 having the above configuration will be described in detail with reference to FIGS. 1 to 3.

First of all, according to the application equipment, the power supply code 28 and the test code 30 shown in Figs. 2 and 3 are preferably selected according to the type of the ADSL modem by using the selector switch 14. To combine. At this time, for example, the jack 28a of the power supply cord 28 is coupled to the modem and the jack 28b is coupled to the DC terminal 12 for 5V, and also the jack 30a of the test cord 30 ) To the modem terminal.

Next, the jacks 30a and 30b of the test cord 30 are connected to the ADSL line, and the line state is checked using a lamp of a modem. Then, it is possible to easily measure the abnormality of the ADSL line, and the work preparation time and the measurement time are significantly shortened.
