Abstract
A broadband line interface circuit has a transmission module and a reception module. The transmission module has a parallel-to-serial converter 11 that receives data from a multiplexer 14 that multiplexes data from one or more input data tributaries. The transmission module also has a randomizer 15, a transmission clock generator 12, and a parity generator 13. The receiver module has a serial-to-parallel converter 33 that receives data under control of a reception clock generator 34. The serial-to-parallel converter sends parallel data to a demultiplexer 36 and to a parity verification block 32. A derandomizer 37 is connected with the demultiplexer 36, which demultiplexes the data onto one or more output data tributaries.
