A ACCESS GATEWAY SYSTEM HAVING DUAL SUB-HIGHWAY STRUCTURE

摘要

The present invention relates to an access gateway system of the overlapping sub-highway SHW matching portion and overlapping sub-highway structure of the structure of the access gateway system, SHW matching of the overlapping sub-highway structure according to the present invention comprises: a second transmission data transmitted from the subscriber block of multiplexing to transmit the signal to the switch block via one of the SHW cable during one clock period of the multiplexer; The SHW through cable separating the superimposed data signals transmitted from the switch block to the two data signal by including a de-multiplexer for transmitting to the access block is characterized in that for transmitting two bits of data in one clock cycle. Further, here, the multiplexer, the clock is high (HIGH) days when the two of the transmitted data signals over the first transmission data signal is SHW cable and to be transmitted to the switch block, and the other when the clock is low (LOW) claim characterized in that the second transmission data signal to be transmitted to the switch block through the same cable SHW.
