An inverse multiplexer breaks a data stream into multiple links that are transmitted at a lower speed. The inverse multiplexing device relates each of the low-speed streams to the others, so they all carry the same data together. Another inverse multiplexer re-aggregates the streams where higher-speed transport becomes necessary. This is the opposite of a multiplexer, which creates one high-speed link from multiple low-speed streams.
RAD’s inverse multiplexers span the gap between E1/T1 and E3/T3, enabling provision of a mid-field of bandwidth without using more expensive – and often wasteful – E3/T3 lines. A common application is transmission of a single high-speed data channel over up to four standard 2-wire SHDSL links or E1/T1 lines, while solutions are also available for leased lines, wireless networks, access to SDH/SONET, and more. A built-in Ethernet bridge/router connects 10/100BaseT LANs to the devices, and adaptive bandwidth supports extended transmission ranges over SHDSL lines.
RAD’s inverse multiplexers transfer Ethernet packets transparently, enabling service providers to use their next-generation equipment in a TDM environment.
