Description

[0001] The present invention relates to an installation structure for a subscriber line,

The present invention relates to an installation structure of a telecommunication cable subscriber line for easily installing subscriber lines of a plurality of broadcasting communication providers and reliably preventing the subscriber lines from being restrained once installed.

Generally, there are two types of installation structure of subscriber charger for processing communication cable of broadcasting company.

As shown in Fig. 1, machined coaxial cables and machined optical cables of broadcast communication companies are hanged and processed in a wire line installed in a keon electric pole 1, and coaxial cables branched from the tap off (T) And the optical cables branched from the branch box 1a provided in the processed optical cable are individually connected to the surrounding users.

The optical cable of KT extends upward in the ground of the communication electric pole 2 to reach the terminal box 2a disposed in the communication pole 2 and the optical cables branched from the terminal box 2a are individually .

In Seoul, there are many multi-family houses where several generations live in one building. In such a multi-family residential area, it is common for each broadcasting company to connect the communication line to the user's building through the subscriber charters (8).

Residents in this multi-family residence are relatively frequent, and each broadcasters is highly competitive to secure their customers. In this context, when residents in multi-family housing are changed, new residents frequently receive broadcast communication services through other providers.

The new operator cuts and abandons the existing subscriber line 8 and performs installation work to connect the new subscriber line 8 to the building from their processed communication cable. As this practice has been going on for a long time, broadcasting services have been stopped in the multi-generations, which are the residential areas of the common people, but subscriber charities (8)

As a result, civilian complaints have been generated by the public, and the government has decided on an aerial maintenance plan at the 11th meeting of the People's Daily Living Measures Review Committee (Nov. 23, 2012) .

In the result report of the meeting of the head of the team leader of the aeronautical maintenance department of Seoul Metropolitan City held on October 1, 2013, the aeronautical maintenance guideline distributed is limited in the work of dismantling of the abandoned ship and the bundling of the incoming line. It is pointless to point out that there are some cases where the maintenance area is the same as before maintenance after several months.

2015.11.16 The Government of the Republic of Korea convened a meeting of ministerial affairs ministers under the presidency of the Office of the Coordinator for State affairs to discuss ways to improve public cable maintenance. The main revision is to introduce a common use system of subscriber lines between operators in order to prevent the overflow of public cable.

The photographs of FIGS. 2 and 3 show the structure in which the processed communication cable subscriber lines 8 are connected to the user building. According to these pictures, tap-offs (T) or dispensers (1a) are installed on the exterior wall of the building in an exposed state, and the subscriber lines are passed through the tap-off (T) or dispenser It is connected to the user through the veranda.

FIG. 4 is a plan view showing a state in which subscriber lines are maintained through maintenance work currently performed in a multi-family housing area, and FIG. 5 is a side sectional view. This maintenance method is based on the fact that the subscribing charitable lines (8) starting from Jeonju are raised on the roof of the multi-family house and exposed through the tap-off or terminal box exposed on the roof railing, So that they have a structure in which they enter the user household and are connected to each other.

In the meantime, the technical standard prescribed by the relevant laws and regulations is "If the CO line is more than five lines, it should be brought underground in accordance with FIG. 6, and the CO line 5a that is drawn in should be installed in the device box 4 installed at the boundary point with the subway line 8b. In the case of the That is, the installation structure of the subscriber line according to the current method of repairing the telecommunication cable is a violation of the technical standard prescribed by the relevant laws and regulations.

The problems caused by violation of these technical standards are as follows.

First, the processing communication cable subscriber charger 8, which is individually connected to the user in the exchanging facilities 1a and 2a installed in Jeonju, is exposed to the outside of the air and the building, thereby damaging the beauty of the city.

Second, the trunk line is drawn into the apparatus box 4 installed at the boundary point and is not connected to the underground line 8b, so that the user broadcasting communication facility becomes useless.

Third, whenever a user wishes to change a business entity, the subscriber charity line 8 connected to the user is newly installed in the exchange facility of the business operator installed in the previous week, thereby causing the subscriber charity line 8 to be refrained.

The reason why broadcasting service providers do not comply with the technical standards is as follows. First, when a coaxial cable trunk line or optical cable trunk line 8a classified by each operator enters into the device box 4 and connects with the public line 8b, 8b) and the type of communication line are different.

Fourthly, when the CO line is inserted into the device box 4 through the inlet pipe 6, the CO line inserted into the inlet pipe 6 becomes an obstacle, so that the CO line inserted later by the operator inserting the CO line It was difficult to work.

SUMMARY OF THE INVENTION The present invention has been conceived to solve the above-mentioned problems, and it is an object of the present invention to provide a method and a system for facilitating the operation of introducing a CO line into a device box through an in- The present invention has been made to provide a structure for installing a communication cable subscriber line to improve the indoor environment by restoring the beauty of the city, preventing the re-enforcement,

In this case, the CO line may be housed in a cabin installed on the front of the road after extending up to a certain height through a CO line inlet pipe and / or a processing inlet pipe connected to a communication manhole in the cabin.

In addition, the trunk line may include an extra fiber trunk line for future change.

On the other hand, if the subway line arranged inside the apparatus box is a coaxial cable, it can be connected to the optical fiber CO line via the optical converter.

In addition, if the intra-city pipeline does not have an intra-city line that can be connected to the optical fiber CO line, it is preferable that the intra-city line is connected to the CO line after inserting the optical fiber intra-

In addition, the optical fiber carrier lines extended from the exchange facility installed in one electric pole to the other electric pole may have a structure to be inserted into one connected optical cable.

The installation structure of the inventive processing communication cable subscriber line is as follows. First, all the business lines originating from the operator exchange facilities are collected by the electric pole installed at the upper part of the electric pole, and the optical fiber coaxial lines connected to the business lines are connected So that the communication cable can be prevented from spreading to the outside of the building and the public, so that the beauty of the city can be maintained.

Second, fiber-optic trunks connected to all service lines enter the device box. Therefore, when a user wants to replace a service provider providing a broadcast communication service, it is easy to replace the user's public line with the trunk line of another service provider in the device box . That is, when the user changes the broadcasting communication service provider, the problem of re-establishment caused by re-installing the subscriber line is fundamentally resolved.

It must be interpreted in terms of meaning and concept.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. The same reference numerals are used for the same components, and only the different portions are described for the sake of clarity.

The meaning of terms used in the present invention will be described.

A subscriber charter means an entire line composed between users' terminals in the exchange facility of a business operator.

The term "trunk line" means a circuit composed between the original exchange facility and the first terminal of the user broadcasting communication facility. However, in the present invention, the term "trunk line" refers to a line formed between a device box or a trunk line terminal box installed in a building in a pole housing installed on the top of a pole, and a carrier line refers to a line formed from a trunk exchange facility to a switching center.

A paved line means a line composed between a device box or a trunk terminal box to the user's generation.

The equipment box means a distribution box in which an amplifier and a distributor are installed to distribute the terrestrial broadcast, satellite broadcast and general cable broadcast lines to each household or floor.

A trunk terminal box means a distribution box for communication that interconnects the trunk line and the subway line.

Since the apparatus box is for a broadcasting line and the trunk line terminal box is for a communication line, the boundary between broadcasting and communication gradually disappears, so that the term " apparatus case "

Jeonju Cham is a distribution box installed at the upper part of the Jeonju and connected to the CO line extending to the upper part of Jeonju via the CO line and the business line connected to the exchange facility of the business operator.

First, the installation structure of the CO line extending from the device box to the electric pole installed in the upper part of the electric pole through the CO line inlet pipe will be described.

In the present invention, a provider optical fiber trunk line is included in one optical cable, so that the operation of each business trunk line can be facilitated through the trunk lid to the apparatus box through the trunk line input pipe. It is one of the important features of the present invention that all the CO trunks are integrated into an optical fiber and included in one optical cable. This makes it easy to insert the CO cable into the CO line and make it possible to jointly use the CO line.

7 and 8, when the CO line inlet pipe 6 connected to the lower portion of the electric pole 1 has a passage extending to the unit box 4 via the communication manhole 3, the CO line 8a Is extended from the device box 4 to the upper portion of the electric pole 1 via the CO line inlet pipe 6 and the communication manhole 3 so as to be housed in the electric pole box 10 installed on the upper portion of the electric pole 1 do.

7 and 9, when there is an obstacle such as a road between the building in which the apparatus box 4 is installed and the electric pole 1 and the CO line inlet pipe 6 is not connected to the lower portion of the electric pole 1 The duct 8a is connected to the device housing 4 via the communication manhole 3 and the CO line inlet pipe 6 through the process inlet pipe 7 fixed to the outer wall of the building, Is extended to the upper portion of the charge inlet line 6, the communication manhole 3 and the processing inlet line 7 in the casing 4 and then extended to the electric pole 1 where the carrier lines 8c are collected, And is housed in the former housing 10.

It is desirable that the pole housing 10 be installed at a height below the height of the processed communication cable so that the passengers can not easily reach the ground from the ground. This electric pole box 10 is connected to a coaxial line 8a extending from the device box 4 to the upper portion of the electric pole 1 through the coin entry pipe 6 and to the exchange facility 1a, The line 8c is connected and the connection between the line 8a and the line 8c is protected by an external impact.

The electric pole box 10 disposed on the upper part of the electric pole 1 may be arranged independently by dividing the coins 8a starting from one device box 4 or may be arranged separately from other adjacent device boxes 4 And may be disposed separately from the trunk lines 8a.

After repairing the subway lines 8b installed in the inner pipe lines extending from the device box 4 to each user's household, the optical fiber CO line 8a drawn into the device box 4 is connected to the subway line 8b 8a and 8b are as follows.

In the building (4) of the building, there is an installation box for the installation of a broadcasting station and a trunk terminal box for communication. In a typical multi-family house, there are both a coin acceptance facility and a terminal box for communication. However, an old house or building may have only a terminal box for communication.

As shown in FIGS. 10 and 11, the installation structure of the CO line 8a and the subway line 8b is such that after the subway line 8b is inspected and repaired so as to correspond to the optical fiber CO line 8a drawn into the apparatus case 4 , And connects the introduced optical fiber trunk line 8a to the subway line 8b.

The practical cases are as follows. However, since the branch of the optical fiber trunk line 8a belongs to a general matter, a detailed description will be omitted.

First, when the subway line 8b is a coaxial cable, the coaxial cable 8a is connected to the coaxial cable suspension line 8b via an optical converter, or the coaxial cable suspension line 8b is replaced with an optical fiber suspension line 8b The optical connector can be connected to the ends of the trunk line 8a and the subway line 8b and connected to each other through the adapter.

Second, when the subway line 8b is an optical fiber, the optical connector is connected to the end of the subway line 8a and the subway line 8b and is connected to each other through the adapter.

Thirdly, if the building is provided with only the telephone line in the apparatus box 4 and the piping in the premises and the public wire 8b which can be connected to the optical fiber trunk line 8a is not provided, the optical fiber duct 8b is additionally inserted into the pipe And the optical fiber trunk line 8a is interconnected with the optical fiber trunk line 8b.

The optical fiber or the optical cable is thin, and it is possible to connect the device box 4 and each user's household through the communication trunk line inlet pipe 6. Also, the optical connector and the adapter used for interconnecting the optical fibers are small, so that it is possible to connect the optical fiber trunk line 8a and the optical fiber suspension line 8b inside the narrow device box 4.

Next, the installation structure of the carrier is explained.

In the present invention, the optical fiber trunk lines 8a led into the pole holder 10 installed on the pole can be connected to the operator exchange facilities 1a and 2a installed on other poles as well as the pole pole through the carrier line 8c. Let's look at a practical example that implements it.

The electric pole box 10 to which the carrier line 8c and the trunk line 8a are connected may be provided in the electric pole electric pole 1 or in the electric pole 2. In the residential area, there are many cases where KEPCO Jeonju (1) and Jeonju (2) are located between roads.

The switching facilities 1a and 2a of the business operator have a tap-off provided on the coaxial cable suspended from the wire bundle suspended on the electric wire 1 and a branch box provided on the processed optical cable and a terminal box provided on the upper portion of the communication pole 2.

Business lines 8c connected to the exchange facilities 1a and 2a of such a provider are connected to the fiber-optic trunk lines 8a by being drawn into the pole housing 10, and a specific example thereof will be described below.

The coaxial cable operator's branch which branches off at the tab-off hanging from the hanger line of the KEPCO electric pole 1 and enters the electric pole 10 is changed to the optical fiber carrier line 8c via the optical converter and is connected to the optical fiber CO line 8a . The optical fiber carrier line 8c connected to the optical distribution box suspended from the hanger line of the KEPCO electric pole 1 is directly inserted into the electric pole 10.

On the other hand, as shown in Fig. 12, the optical fiber business line 8d provided in the communication electric pole 2 is raised in the lower portion of the electric pole 2, passed through the terminal box 2a, Lt; / RTI >

The optical fiber trunk lines 8a drawn into one pole holder 10 are connected to the exchange facility 1a of the operator installed on the electric pole 1 through the optical fiber carrier lines 8d and 8e inserted inside the link optical cable 11, But also to the exchange facility 2a of the business operator installed in the other electric pole 2.

The connecting optical cable 11 is connected to the trunk line 8a to which the carrier line 8d connected to the company switching facility 2a installed on one electric pole 2 is led into the pole tray 10 of the other electric pole 1 Refers to a structure in which the optical fiber line portions extending between the electric pole 2 and the electric pole 1 are inserted into a bundle or optical cable.

This connecting optical cable 11 helps to secure the aesthetics of the city by reducing the number of communication lines spreading on the road.

In the present invention, it is an important technical feature that all business lines 8c, 8d, and 8e can be connected to the optical fiber CO line 8a. The problem is that the business line 8c branching from the machined coaxial cable is connectable to the optical fiber trunk line 8a.

In the simplest technical configuration, the input side of the optical converter for E / O transmission is connected to the branch bar branched at the tap-off connected to the working coaxial cable, and the optical fiber carrier line 8c is connected to the output side of the optical converter To come out.

In the second technical construction, the input side of the optical converter for E / O transmission is connected to the coaxial cable branched from the tap-off connected to the working coaxial cable, and the optical fiber carrier line 8c or the optical fiber coaxial cable 8c is connected to the output side of the optical converter. (8a) are connected to each other.

The third technical construction is that the E / O optical converter for transmission to the branch circuit adds an electrical signal branch PCB which is disposed in the lower housing of the tap-off and branches the electric signal to be introduced into the upper plate, as described in the preamble of the present invention To an optical converter PCB that is switched to an optical signal.

In the fourth technical construction, the optical coaxial cable connected from the electric pole 10 to the optical network unit (ONU) is replaced by the optical cable, and the optical fiber carrier 8c branched from the optical cable is connected to the electric pole 10). This also has the effect of preventing redundant investment that occurs when a broadcasting service provider unifies the entire communication network with an optical fiber.

The pole housing 10 of the communication pole 2 may be provided separately from the terminal housing 2a and the terminal housing 2a may also serve as the pole housing 10 of the communication pole 2 . At this time, although not shown, the optical fiber business line 8d, which is placed on the lower portion of the communication pole 2, is directly introduced into the pole housing 10 of the communication pole 2.

FIG. 13 is a systematic diagram showing the relationship between the operator exchange facilities 1a, 2a, the carrier line, the electric pole box 10, the trunk line 8a, the apparatus box 4 and the hallway 8b in the present invention. 13, business lines 8c, 8d and 8e connected to the processing communication cable company switching facilities 1a and 2a in the present invention are gathered by the electric pole box 10 installed on the upper part of the electric pole, And the CO line 8a is connected to the subway line 8b and the subway line 8b is connected to the user's household.

The connection between the subway line 8b and the optical fiber trunk lines 8a is performed after repairing the subway lines 8b from the device cabinet 4 to the respective users so as to be connectable with the optical fiber trunk lines 8a .

The installation structure of the inventive processed communication cable subscriber line is as follows. First, the business lines 8c, 8d, 8e installed in the electric pole 1 are collected in the electric pole housing 10 to be connected to the trunk lines 8a, 8a are led into the apparatus box 4 and connected to the subway line 8b so that the subway line 8b recovers the communication line connected to the user's household, It has the effect of restoring beauty.

Secondly, the trunk lines 8a connected to the trunk lines 8c, 8d and 8e of all the trunkers are connected to the trunk line 8b of the user by being drawn into the trunk box 4. Therefore, And the worker completes the work of replacing the public line 8b of the user with the trunk line 8a of another business entity and connecting them. In other words, the problem of re-enforcing the provider's business due to the replacement of the operator by the user is fundamentally resolved.
