ABSTRACT:
A low/medium speed subscriber multicasting device for an asynchronous mode cell, the device may be constructed with an integrated routing table on which integrated information including the multicasting routing tables necessary for each low/medium speed subscriber's link, is mapped; and a multicasting call processing unit for receiving information from a control process in a higher layer block, for mapping out the virtual path/virtual channel and port number corresponding to the multicasting copy number of a link in the integrated routing table when receiving a multicasting cell, for accessing the routing table using the multicasting copy number and link information for the multicasting cell to read virtual paths/virtual channels for each link, and for transmitting the multicasting cell to the corresponding low/medium speed subscriber's link.
