Abstract
For rearranging the time slots of an incoming frame according to a specified order and generating an outgoing frame. A time base generates timing pulses at intervals N times greater than the intervals at which the incoming and outgoing frames are generated, where N is an integer equal to or greater than 2. There is provided a dual-port random access memory capable of writing the time slots of a given incoming frame into memory cells and simultaneously reading the time slots of a rearranged version of a frame preceding the given incoming frame. A write address code is supplied to the random access memory in response to each of the timing pulses to write N successive incoming frames and a read address code is generated in accordance with a switching control signal and supplied to the random access memory in response to each of the timing pulses to read N successive outgoing frames.
