Description

공중회선과 전용회선을 통한 저속데이타의 통계적 다중화장치Statistical Multiplexing Device of Low Speed Data through Public Line and Dedicated Line

본발명은 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 leased line and a public 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 호스터 컴퓨터(108)에 데이터를 전송할 때 도 1의 전용회선용 통계적 다중장치는 전용회선용 저속데이터를 전용회선용저속데이타송수신기(101)가 송신한 데이터를 전용회선용저속데이타통계적다중화장치(103)에서 다중화하여 1차 통계적 다중화장치(105)에 전송하고,상기 1차 통계적 다중화장치(105)는 2차,3차 n차통계적 다중화장치(107)를 통하여 호스트 컴퓨터(108)에 데이터를 전달한다.그리고 도 2의 예와같이 공중회선을 통하여 공중회선용 저속데이타(300bps)송수신기(201)가 호스트컴퓨터(209)에 데이터를 전송하는 것도 공중회선용 저속데이터를 공중회선용저속데이타송수신기(201)가 송신한 데이터를 공중회선용저속데이타통계적다중화장치(203)에서 다중화하여 1차 통계적 다중화장치(205)에 전송하고,상기 1차 통계적 다중화장치(205)는 2차,3차 n차통계적 다중화장치(207)를 통하여 호스트 컴퓨터(209)에 데이터를 전달한다.즉 상기 전용회선과 같은 경로와 방법을 통하여 이루워진다.그러나 종래는 도 1,2의 예와같이 전용회선용 및 공중회선용 접속데이타 송수신기(101,201)가 호스트컴퓨터(108,209)에 데이터를 전송하기 위해서는 전용회선용 통계적 다중화장치(103)혹은 공중회선용 통계적 다중화 장치(203)와 수개의 1차 통계적 다중화 장치를 통해야 전송이 가능하므로 1개의 전용회선용 혹은 공중회선용 저속데이타를 호스트 컴퓨터(108,209)에 송신하기 위해서는 3대이상의 장치가 필요하며, 또한 장치들이 여러곳에 분산되어 있어 데이터의 전송지연 및 분실, 깨짐현상이 발생되는 문제점이 있다.When the transceiver of the low speed data (300 BPS or less) transmits the data to the host computer 108 through the dedicated line as in the examples of FIGS. 1 and 2, the statistical multiple device for the dedicated line of FIG. 1 is dedicated to the low speed data for the dedicated line. The data transmitted by the low speed data transmitter 101 for the line is multiplexed by the low speed data multiplexer 103 for the dedicated line, and transmitted to the primary statistical multiplexer 105, wherein the primary statistical multiplexer 105 is 2; The data is transmitted to the host computer 108 through the third and third order statistical multiplexing devices 107. The low speed data transmitter (300bps) for the public line through the public line as shown in FIG. The transmission of the data to the computer 209 is also performed by multiplexing the data transmitted by the low speed data transmitter 201 for the air line by the low speed data multiplexing device 203 for the air line and performing primary statistical analysis. The primary statistical multiplexer 205 transfers data to the host computer 209 through the secondary and tertiary n-th order multiplexers 207. That is, the dedicated line However, in the related art, the dedicated data for the dedicated line and the public line connection data transceivers 101 and 201 transmit data to the host computer 108 and 209, as shown in the examples of FIGS. 1 and 2, respectively. Since the transmission is possible only through the multiplexing device 103 or the statistical multiplexing device 203 for the public line and several primary statistical multiplexing devices, in order to transmit one dedicated line or low-speed data for the public line to the host computer 108 or 209, Three or more devices are required, and there is a problem in that the devices are distributed in several places, causing delays in data transmission, loss, and breakage.

따라서 본발명의 목적은 공중회선 및 전용회선을 통해 수신되는 데이터(300bps이하)를 통계적 다중화하는 전용회선용 통계적 다중화장치, 공중회선용 통계적 다중화장치, 그리고 전술한 두장치로부터 수신된 데이터를 다시 통계적 다중화하는 장치를 단일 장치에 수용하여 호스트컴퓨터에 통계적으로 다중화한 데이터로 전송할 수 있는 장치를 제공함에 있다.Therefore, the object of the present invention is to statistically multiplex the data received through the public line and the leased line (less than 300bps) for the dedicated line statistical multiplexing device, the public line statistical multiplexing device, and the data received from the two devices. The present invention provides a device capable of accommodating multiplexing devices into a single device and transmitting statistically multiplexed data to a host computer.
