Description

IDC telecom block

The present invention relates to an IDC telecom block, and more specifically, it is possible to connect two extension lines (callout line) connected to the local station of the telephone line per incoming line (entry line) connected to the subscriber side. (Inlet line) It is related to IDC telecom block that can connect ADSL or VDSL when not only two telephone lines can be connected per line but also one telephone line per trunk line.

In general, IDC (Insulation Displacement Connection) refers to a method of connecting without removing the insulation line covering.

Conventionally, an IDC telecom block is installed in a place where a large number of telephone lines are accommodated and managed such as a telephone station, and when a subscriber line or a relay line is introduced into a telephone station, the line side and the domestic station side are connected. .

In other words, the IDC telecom block divides the circuit by connecting the trunk line (lead line) on the subscriber side with the extension line (leader line) on the domestic station side.

FIG. 1 is a perspective view illustrating an example of such a conventional IDC telecom block, and FIG. 2 is a state diagram illustrating a state in which a trunk line (lead line) and an extension line (leader line) are connected to FIG. 1, and as shown in FIG. A trunk line (lead line) 20 connected to the side is connected, and an extension line (leader line) 30 connected to the domestic station side is connected to the front side to distribute telephone lines, but the trunk line (lead line) 20 is one line The extension (leader line) 30 has a 1: 1 system corresponding to one line.

In the drawings, reference numerals 12 and 14 denote IDC connecting pins to which trunk lines (lead lines) and internal lines (leader lines) are connected, respectively.

Recently, the IDC telecom block 10 is laminated and combined to form a copper cable cluster, and a housing for providing high-speed communication service (ADSL, VDSL) by accommodating a cluster of the mobile cable and various communication devices is provided outdoors. It is installed in the apartment complex.

Such outdoor enclosures generally include a heat storage unit, a power distribution panel, an optical distribution panel, a rectification base, a battery storage box, a heat exchanger, a copper cable cluster, and an optical transmission device.

The copper cable cluster is connected to the device side and subscriber side of the telephone station in one IDC telecom block, and as shown in FIG. 3, a splitter (combiner) and a protector are connected to the IDC telecom block by forming a jack. It provides a connection (Inter-connection) method, a single connection code that combines the protector and splitter into a single code for ease of operation.

That is, the telephony service provides a splitter to provide a service by directly connecting from the subscriber's trunk line (leader line) to the telephone station's internal station (leader line) by the IDC access pin inside the IDC telecom block A. Is a signal (voice + data signal) is transmitted to the IDC telecom block (A) at the subscriber extension (leader), the splitter is divided into a voice signal and a data signal, and the data signal is separated from the transmitter IDC telecom block (B). It is then sent to the optical transmission equipment. In addition, the voice signal is transmitted from the splitter to the telephone network through an internal telephone line (outgoing line) connected to the IDC telecom block A.

Therefore, one IDC telecom block has no choice but to connect the subscriber's trunk line (incoming line) as many as the number of IDC connection pins. Therefore, many IDC telecom blocks need to be installed where a lot of telephone lines are required. In addition, the installation cost is not only high, but as a single line (leader line) is connected to the trunk line (leader line), a number of lines are connected and eventually the maintenance of the lines is not easy.

On the other hand, in order to provide a high-speed data service to the subscriber side, it is necessary to have a separate IDC telecom block connected to the optical transmission equipment and to connect the splitter and the protector with one code. In this case, a plurality of IDC telecom blocks are connected. The installation requires a lot of installation space and costs a lot of installation costs, and because a number of lines are connected due to the addition of a line for connecting a splitter and a protector, this also makes it difficult to manage or maintain the line. there was.

Therefore, the present invention was devised to solve the above-mentioned problems, and it is possible to connect two lines of extension (leader line) of the domestic station per call line (leader line) of the subscriber side, and eventually subscriber line (Incoming line) It is possible to connect two telephone lines per line as well as to provide IDC telecom block that can additionally connect ADSL or VDSL when one telephone line is connected per line (incoming line). There is this.

The IDC telecom block of the present invention for achieving the above object is installed in a place that accommodates and manages a large number of telephone lines, such as a telephone station, and when the subscriber line or relay line is introduced into the telephone station, the line side and line switches and telephones. In the IDC telecom block that serves to connect the domestic equipment side, the front side to which the extension line (outgoing line) connected to the domestic equipment side is connected in response to the IDC connection pin on the back side to which the trunk line (incoming line) connected to the subscriber side is connected. IDC connecting pin is characterized in that the 1: 2 configuration.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 4 is a perspective view of the IDC telecom block according to the present invention, Figure 5 is a perspective view of the use state of Figure 4, the IDC connecting pin 52 of the rear side to which the trunk line (lead line) 20 connected to the subscriber side as shown ), The IDC connecting pin 54 on the front side to which the extension (leader line) 30 connected to the telephone station equipment side is connected in a 1: 2 manner.

That is, two lines of the internal line (lead line) 30 are connected to one line of the trunk line (lead line) 20 to form a Y connection, and IDC connection pins 52 and 54 are formed at both sides of each port. Finally, four internal lines (leader lines) are connected to two trunk lines.

Therefore, two subscriber lines (outgoing lines) 30 are connected to one subscriber line (line) 20, so that one subscriber can connect two telephone lines to one line of the trunk line (lead line) 20. In the case of connecting a telephone line of one line to a trunk line (incoming line) 20, an ADSL or a VDSL can be additionally installed.

For reference, in the present invention, an IDC telecom block of 8 ports has been described as shown in the drawing. IDC connection pins are provided at both sides of each port, and thus, a total of 8 subscriber side trunk lines (entry lines) are provided. You will be able to connect 16-line telephone lines or ADSL and VDSL.

As described above, according to the IDC telecom block according to the present invention, the subscriber side trunk line (leader line) is configured to connect two extension lines (leader line) connected to the station side of the subscriber station. ) Since two telephone lines can be connected to one line, a larger number of telephone lines can be connected with one IDC telecom block, which reduces the installation space of the IDC telecom block and reduces the installation cost by reducing the number of parts. There is a useful effect.

In addition, in case of connecting one telephone line per subscriber line (incoming line), ADSL or VDSL can be additionally connected. IDC telecom block is installed in duplicate to connect ADSL or VDSL as in the prior art. Therefore, there is no need to bundle and connect the splitter and the protector with a single cord, which also has a useful effect of reducing the installation cost and reducing the installation space.
