Multi-port time switch element

摘要

A multi-port time switch element for cross-connecting an n-channel multiplexed data includes m input ports for receiving m n-channel multiplexed data, a memory part for alternately writing and reading the n-channel multiplexed data, m selectors for writing and reading the n-channel multiplexed data so that each of the m selectors receives mxn data read from the memory part and selects one of the mxn data n times in an arbitrary sequence to output an n-channel multiplexed data, and m output ports for outputting the m n-channel multiplexed data read from the m selectors.
