Description

전주형 오앤유 시스템에서의 스플리터 내장형 단자반{Connection board incorporated with splitter in optical network unit}Connection board incorporated with splitter in optical network unit

본 발명은 FTTC(Fiber To The Curb) 형태의 망에서 가입자측 ONU(Optical Network Unit) 통신시스템에 사용될 단자반에 관한 것으로서, 가입자측 ONU 통신시스템의 설계효율을 향상시키는 xDSL/POTS 스플리터(Splitter)를 내장한 단자반에 관한 것이다.The present invention relates to a terminal board to be used for a subscriber-side optical network unit (ONU) communication system in an FTTC (Fiber To The Curb) type network, and includes an xDSL / POTS splitter for improving design efficiency of a subscriber-side ONU communication system. It relates to a terminal board having a built-in.

도 1은 전주형 ONU를 포함한 일반적인 광가입자망을 설명하기 위한 도면이다.1 is a view for explaining a general optical subscriber network including the pole-type ONU.

도 1에서, 광케이블을 통하여 중앙국사(100)와 접속된 ONU(120)는 수신된 광신호를 전기적 신호로 변환하여 각 가입자(136)에게 전송하며, 가입자(136)측에서 선로(134)를 통하여 전송된 전기신호는 역으로 ONU(120)에서 전기적 신호를 광신호로 변환하여 중앙국사(100)로 전송한다.In FIG. 1, the ONU 120 connected to the central office 100 through an optical cable converts the received optical signal into an electrical signal and transmits the signal to each subscriber 136, and transmits the line 134 on the subscriber 136 side. On the contrary, the electrical signal transmitted through the ONU 120 converts the electrical signal into an optical signal and transmits it to the central office 100.

여기서, ONU(120)는 수신된 광신호를 전기신호로 변환하거나 가입자(136) 측으로부터 전송된 전기신호를 광신호로 변환하여 광케이블로 전송하기 위한 전/광, 광/전 변환부(122), 물리 계층 처리, ATM 계층 처리, 서비스 다중화/역다중화 기능 등을 처리하는 정합부(126)와, 전화신호와 xDSL신호를 별도로 각각 처리하는 전화서비스 보드(128)와 xDSL서비스 보드(130), 전화서비스 보드(128)와 xDSL서비스 보드(130)를 각 가입자들의 전화선과 접속시키는 단자반(132)으로 구성된다.Here, the ONU 120 converts the received optical signal into an electrical signal or converts the electrical signal transmitted from the subscriber 136 into an optical signal and transmits the optical signal to the optical cable. Matching unit 126 for processing physical layer processing, ATM layer processing, service multiplexing / demultiplexing function, telephone service board 128 and xDSL service board 130 for separately processing telephone signals and xDSL signals, The terminal board 132 connects the telephone service board 128 and the xDSL service board 130 to the telephone lines of the respective subscribers.

도 2는 종래의 ONU에서의 단자반과 전화 및 xDSL 서비스 보드와의 접속관계의 일예를 설명하기 위한 블록도로서, 스플리터가 전화서비스 보드내에 설치된 경우를 도시한다.Fig. 2 is a block diagram for explaining an example of a connection relationship between a terminal board, a telephone, and an xDSL service board in a conventional ONU, and shows a case where a splitter is installed in a telephone service board.

도 2에서, 각 가입자측으로부터 인입된 선로들은 단자반(200)을 통하여 전화서비스 보드(202)와 연결되어 있으며, 가입자측으로부터 전송된 분리되지 않은 신호(210)는 단자반(200)을 통하여 전화서비스 보드(202)내의 장착된 스플리터(204)에 전송되어 xDSL신호와 전화신호로 분리된다.In FIG. 2, the incoming lines from each subscriber side are connected to the telephone service board 202 through the terminal board 200, and the unseparated signal 210 transmitted from the subscriber side is connected through the terminal board 200. It is transmitted to the splitter 204 mounted in the telephone service board 202 and separated into an xDSL signal and a telephone signal.

이때, 전화서비스보드(202) 내의 스플리터(204)에서 분리된 전화신호(212)는 전화서비스 보드(202)에서 처리되지만, xDSL신호(214)는 백플레인(206)을 통하여다시 xDSL서비스 보드(208)로 전송되어 신호처리된 다음 광신호로 변환되어 광케이블을 통하여 중앙국사에 전송된다. 또한, 가입자가 xDSL 서비스를 제공하는 통신회사와는 다른 통신회사의 전화서비스에 가입되어 있는 경우, 스플리터(204)에서 분리된 해당 가입자의 전화신호(216)는 백플레인(206)을 거쳐 다른 통신회사에서 서비스하는 미도시된 ONU로 전송된다.At this time, the telephone signal 212 separated from the splitter 204 in the telephone service board 202 is processed by the telephone service board 202, but the xDSL signal 214 is again transmitted through the backplane 206. ) Is processed and signal is processed and then converted into optical signal and transmitted to central office through optical cable. In addition, when the subscriber is subscribed to a telephone service of a communication company different from the communication company providing the xDSL service, the telephone signal 216 of the subscriber separated from the splitter 204 is transmitted through the backplane 206 to another communication company. Is transmitted to the ONU, not shown.

이러한 ONU 시스템에서의 종래의 단자반은 단순히 접속 단자들이 배열된 구조로서, 가입자측의 댁내와 연결된 외부 선로를 통신 시스템내의 보드들과 연결시켜주는 기능만을 하였다.The conventional terminal board in the ONU system simply has a structure in which connection terminals are arranged, and has only a function of connecting an external line connected to a subscriber's premises with boards in a communication system.

이에 따라, 전화서비스 보드(202) 또는 xDSL서비스 보드(208)에 스플리터(204)를 내장시키는 통신시스템은 xDSL과 전화서비스 보드 중 어느 보드가 스플리터를 수용하던지 간에 서비스보드에서 분리된 신호들 중 한 종류의 신호는 해당 신호들을 처리하는 서비스보드로 신호가 접속되도록 백플레인을 설계를 해야 하였다.Accordingly, a communication system in which the splitter 204 is embedded in the telephone service board 202 or the xDSL service board 208 may use one of signals separated from the service board whether the xDSL or the telephone service board receives the splitter. Kinds of signals had to be designed so that the signals were routed to the service board that processes them.

따라서, 백플레인의 설계가 매우 복잡해지는 문제점이 있었으며, 스플리터가 설치된 서비스 보드는 크기가 커져서 소형화 추세에 있는 소규모 가입자 통신장비에는 바람직하지 않았다. 또한, 스플리터가 백플레인(206)에 수용되도록 설계한 경우에는 백플레인의 크기가 확장되어 수십 가입자의 선로를 수용할 수 있는 소규모 ONU 시스템의 전체 크기가 커지는 문제점이 있었다.Therefore, there is a problem in that the design of the backplane is very complicated, and the service board on which the splitter is installed is not suitable for the small sized subscriber communication equipment which is being miniaturized due to the increase in size. In addition, when the splitter is designed to be accommodated in the backplane 206, there is a problem in that the size of the backplane is expanded to increase the overall size of the small ONU system that can accommodate the lines of tens of subscribers.

본 발명은 상술한 문제점을 해결하기 위해 창출한 것으로서, 전주형 ONU 시스템에서 단자반내의 장착된 스플리터를 통하여 분리된 전화 및 xDSL 신호들이 해당 서비스 보드에 직접 연결될 수 있도록 하여 통신시스템의 설계 효율을 높이고 서비스 보드의 크기를 보다 작게 할 수 있는 스플리터 내장형 단자반을 제공하는 데 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. In the main-type ONU system, the telephone and xDSL signals separated through the splitter mounted in the terminal board can be directly connected to the corresponding service board to increase the design efficiency of the communication system. An object of the present invention is to provide a terminal board with a splitter that can make a service board smaller.

이하, 첨부 도면을 참조하여 본 발명의 실시예를 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3은 본 발명에 따른 스플리터가 내장된 단자반으로 세부 패턴은 생략한 도면이다.3 is a terminal board with a splitter according to the present invention, in which detailed patterns are omitted.

도 4는 ONU 시스템에서 도 3에 도시된 단자반과 전화 및 xDSL 서비스 보드와의 접속관계를 설명하기 위한 블록도이다.FIG. 4 is a block diagram illustrating a connection relationship between a terminal board and a telephone and an xDSL service board shown in FIG. 3 in an ONU system.

가입자측으로부터 전주형 ONU로 전송되는 신호의 처리방향으로 살펴보면, 도 3에서, 다수의 가입자측의 선로와 접속하기 위한 제1커넥터(300)와 전화서비스 보드에서 처리되는 전화신호와 접속하기 위한 제2커넥터(302), xDSL서비스 보드에서 처리되는 xDSL신호와 접속하기 위한 제3커넥터(304)를 구비하며, 가입자측의 선로를 통하여 제1커넥터(300)에 유입된 신호들은 각 스플리터(306)내에 미도시된 필터에 의하여 고주파 신호와 저주파신호로 분리되며, 고주파신호는 xDSL신호로서 제3커넥터(304)로 출력되고 저주파신호는 전화신호로서 제2커넥터(302)로 출력된다.Referring to the processing direction of the signal transmitted from the subscriber side to the pole-type ONU, in Fig. 3, the first connector 300 for connecting with the plurality of subscriber lines and the telephone signal for processing in the telephone service board The second connector 302 and a third connector 304 for connecting with the xDSL signal processed by the xDSL service board, the signals flowed into the first connector 300 through the line on the subscriber side, each splitter 306 A high frequency signal and a low frequency signal are separated by a filter (not shown), and the high frequency signal is output to the third connector 304 as an xDSL signal and the low frequency signal is output to the second connector 302 as a telephone signal.

가입자측의 선로와 각 스플리터(306) 사이에 접속되는 피뢰기(308)는 가입자측 선로상에서 낙뢰 등으로 인해 단자반에 인가되는 써지 전압에 의한 보드의 손상을 방지한다.The arrester 308 connected between the subscriber line and each splitter 306 prevents damage to the board due to surge voltage applied to the terminal board due to lightning or the like on the subscriber line.

도 4에서, 스플리터(336)를 내장한 단자반(330)에 제1커넥터(300)를 통하여 가입자측의 신호(314)가 유입되면 스플리터(336)에 의해 분리된 전화신호(316)와 xDSL신호(318)가 각각 해당 신호를 처리하는 전화서비스 보드(310)와 xDSL서비스 보드(312)로 직접 접속되어 백플레인(322)의 설계가 간단해진다. 가입자가 xDSL 서비스를 제공하는 통신회사와는 다른 통신회사에서 제공하는 전화서비스에 가입되어 있는 경우 다른 통신회사가 지원하는 ONU에 접속하기 위한 전화신호(320)는 단자반(330)에서 외부 선로와 연결되어 미도시된 해당 ONU에 접속된다.In FIG. 4, when the signal 314 on the subscriber side flows into the terminal board 330 having the splitter 336 embedded therein, the telephone signal 316 and the xDSL separated by the splitter 336 are introduced. The signals 318 are directly connected to the telephone service board 310 and the xDSL service board 312, respectively, which process the signals, thereby simplifying the design of the backplane 322. If the subscriber is subscribed to a telephone service provided by a communication company different from the communication company providing the xDSL service, the telephone signal 320 for accessing the ONU supported by the other communication company is connected to the external line at the terminal board 330. Connected to the corresponding ONU, not shown.

도 4에서는 가입자측으로부터 중앙국사에 전송되는 신호의 흐름만 도시하였으나, 전화 및 xDSL 신호가 양방향으로 송수신되므로 스플리터(336) 또한 양방향으로 동작한다.In FIG. 4, only the flow of signals transmitted from the subscriber side to the central office is shown. However, since the telephone and the xDSL signals are transmitted and received in both directions, the splitter 336 also operates in both directions.

본 발명에 의한 xDSL/POTS 스플리터를 내장한 단자반을 적용하면 종래의 ONU시스템에서와 같이 스플리터 장착을 위해 서비스 보드가 크게 확장될 필요가 없으며, 단자반내에서 분리한 전화신호와 xDSL신호를 직접 해당 전화서비스보드와 xDSL서비스보드에 접속시킬 수 있으므로 단순한 백플레인의 설계로 통신시스템 설계의 효율을 높일 수 있다.Application of a terminal board with a built-in xDSL / POTS splitter according to the present invention does not require the service board to be greatly expanded to install a splitter as in the conventional ONU system, and directly corresponds to a telephone signal and an xDSL signal separated in the terminal board. It can be connected to telephone service board and xDSL service board, so the design of simple backplane can increase the efficiency of communication system design.
