Abstract

Abstract Time division multiplex signals arranged in transmission time frames of multibit time slot signals are entered into a first set of plural shift registers arranged to present at predetermined signal transfer points the predetermined signal bits of corresponding bit positions in each time slot of a frame. The predetermined signal bits comprise a miniframe in which each time slot includes only a part of the bits from a time slot in a complete transmission frame. At the end of a transmission time frame, the miniframe signals are transferred to a second set of plural shift registers. The sets of registers are configured for transposing time division signals in either direction between the transmission frame format and the miniframe format depending upon the manner of operation of the transfer between the sets of registers. The shift registers are implemented in magnetic single wall domain technology. Arrangements for either bit-series or bit-parallel interface with other signal paths are considered.
