Abstract
A line card is proposed in which one or more DMT processing modules 1 communicate with a data link layer platform, such as an ATM, POSPHY or Ethernet processor. The data relating to a single symbol is transmitted between the data link layer platform and a given one of DMT processing modules in a plurality of data portions spaced apart in time. The data portions relating to different channels of a given DMT processing module (or to different DMT processing modules) are interleaved in time. Since the data portions of a given symbol are spaced apart in time, the data relating to a single symbol is transmitted over a longer time period than in conventional devices which reduces the effective burstiness of the traffic, and thus reduces the memory requirements of the data link layer platform.
