Abstract

PURPOSE:To prevent the deterioration of transmission performance, by exchanging the information of the time slot in the same frame of incoming highway with that in the same frame of outgoing highway, and avoiding the shift in phase even with multiple-frames. CONSTITUTION:The control memory CMa designating the address of communication memory PM performing the write-in and readout of digital signal takes for the capacity for 2 frames' share, and the address information of the memory PM is written in the address corresponding to the time slot equivalent to the first frame of memory CMa and that equivalent to the second frame respectively in the converse order, allowing to give a given frame delay to the time slot. Thus, the information of the time slot in the same frame of the incoming highway HWi is replaced with that in the outgoing high way HWo, and the phase shift is avoided even with the multiframes, allowing to prevent the deterioration of transmission performance.
