<p><P>PROBLEM TO BE SOLVED: To improve a throughput by suppressing a conversion loss at an ADSL transmission time. <P>SOLUTION: An ADSL encapsulating system includes the encapsulating unit 110A of ATU-R which extracts a packet from the encapsulated packet by encapsulating the packet by inserting a frame bit for a synchronization and an error detecting FCS into the packet for transmitting from the ATU-R to a DSLAM, to the ADSL encapsulating system for ADSL transmitting between ATU-R110 and a DSLAM 111 via a telephone line, and establishing the synchronization to the encapsulated packet transmitted from the DSLAM to the ATU-R and error detecting; and an encapsulating unit 111A of the DSLAM which extracts the packet from the encapsulated packet by encapsulating the packet by inserting a frame bit for the synchronization and an FCS for error detecting to the packet which transmits from the DSLAM to the ATU-R, and establishing the synchronization to the encapsulated packet transmitted from the ATU-R to the DSLAM and error detecting. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
