본 발명은 공중 또는 전용회선용 통계적 다중화장치에 관한 것으로,특히 전송회송용 및 공중회선용 저속데이타 송수신기가 전송한 데이터를 동시에 통계적으로 다중화하는 공중회선과 전용회선을 통한 저속데이타의 통계적 다중화장치에 관한 것이다.The present invention relates to a statistical multiplexing device for a public or leased line, and more particularly to a statistical multiplexing device for a low-speed data through a public line and a leased line for statistically multiplexing data transmitted by a transmission data transmission and a low speed data transmission and reception line for an aerial line. It is about.

종래 도 1,2의 예와 같이 전용회선을 통하여 저속데이타(300BPS이하)의 송수신기가 호스트 컴퓨터(108)에 데이터를 전송할 때 도 1의 전용회선용 통계적 다중장치는 전용회선용 저속데이타 송수신기(101)가 송신한 전용회선용 데이터를 전용회선용 저속데이타 통계적 다중화장치(103)에서 다중화하여 1차 통계적 다중화장치(105)로 전송하고,상기 1차 통계적 다중화장치(105)는 2차,3차... n차통계적 다중화장치(107)를 통하여 호스트 컴퓨터(108)로 데이터를 전달한다.그리고 도 2의 예와같이 공중회선용 데이터에 대해 공중회선용 저속데이타(300bps)송수신기(201)로부터 호스트 컴퓨터(208)로 전송하기 위해서는 공중회선용 저속데이터를 공중회선용 저속데이타 송수신기(201)에서 송신한 데이터를 공중회선용 저속데이타 통계적 다중화장치(203)에서 다중화하여 1차 통계적 다중화장치(205)에 전송하고,상기 1차 통계적 다중화장치(205)는 2차,3차..n차 통계적 다중화장치(207)를 통하여 다중화하여 호스트 컴퓨터(208)로 데이터를 전달한다.즉 상기 전용회선과 같은 경로와 방법을 통하여 이루워진다.그러나 종래는 도 1,2의 예와같이 전용회선용 및 공중회선용 저속데이타 송수신기(101,201)가 호스트컴퓨터(108,208)에 데이터를 전송하기 위해서는 전용회선용 통계적 다중화장치(103)혹은 공중회선용 통계적 다중화장치(203)와 수개의 1차 통계적 다중화 장치를 통해야 전송이 가능하므로 1개의 전용회선용 혹은 공중회선용 저속데이타를 호스트 컴퓨터(108,208)에 송신하기 위해서는 3대 이상의 장치가 필요하며,또한 장치들이 여러곳에 분산되어 있어 데이터의 전송지연 및 분실, 깨짐 현상이 발생되는 문제점이 있다.Conventionally, when the transceiver of the low speed data (300 BPS or less) transmits data to the host computer 108 through the dedicated line as shown in the examples of FIGS. 1 and 2, the statistical multiple device for the dedicated line is a low speed data transceiver 101 for the dedicated line. Dedicated line data transmitted by) is multiplexed by the low speed data multiplexer 103 for the dedicated line and transmitted to the primary statistical multiplexer 105, and the primary statistical multiplexer 105 is a secondary or tertiary order. ... data is transmitted to the host computer 108 through the nth statistical multiplexing device 107. And from the low-speed data (300bps) transmitter for the air line as shown in the example of FIG. In order to transmit to the host computer 208, the data transmitted from the low-speed data transceiver 201 for the air line is multiplexed by the low-speed data statistical multiplexer 203 for the air line, and the primary communication is performed. The first multiplexer 205 transmits the data to the host computer 208 by multiplexing the data through the second and third order ..n-th statistical multiplexers 207. That is, it is achieved through the same path and method as the dedicated line. However, in the related art, as shown in the examples of FIGS. 1 and 2, the low-speed data transceivers 101 and 201 for the dedicated line and the air line transmit data to the host computers 108 and 208. In order to transmit the data through the dedicated multiplexing device 103 or the public line multiplexing device 203 and several primary statistical multiplexing devices, the low-speed data for one dedicated line or air line can be transmitted to the host computer (108,208). 3 or more devices are required to transmit the data, and there is a problem in that data is delayed, lost, and broken due to distributed devices.

따라서 본 발명의 목적은 공중회선 및 전용회선을 통해 수신되는 데이터(300bps이하)를 통계적 다중화하는 전용회선용 및 공중회선용 통계적 다중화장치, 그리고 전술한 두장치로부터 수신된 데이터를 다시 통계적 다중화하는 장치를 단일 장치에 수용하여 호스트컴퓨터에서 통계적으로 다중화한 데이터로 전송할 수 있도록 하는 장치를 제공함에 있다.Accordingly, an object of the present invention is a statistical multiplexing device for leased line and public line statistically multiplexing the data (300bps or less) received through the public line and the leased line, and the apparatus for statistical multiplexing the data received from the above two devices again The present invention provides a device that accommodates a single device and transmits the data as statistical multiplexed from a host computer.
