Abstract
Allowing the implementation of a strictly nonblocking cross-point space switch central stage for the switching of SDH frames or other formats. The port terminating each incoming link has a time slot interchange (TSI) unit. Each TSI unit comprises incoming and outgoing sets of TSI's. The TSI's properly arrange each byte of each row of the STM-1 frame or other formats to be in the proper position for transmission on the STM-1 links. Within the STM-1 frame structure, each row of a frame is switched in an identical manner but the column designations within a row are switched differently. In response to rearranged frames from incoming TSI's, a cross-point switch is responsive to each column of each of the rows to switch each of the bytes of that column to the appropriate outgoing TSI for rearrangement and transmission on a STM-1 link.
