ABSTRACT:
A cross-connect is provided which uses “mask” and “rotate” parameters, rather than “source” and “destination” parameters. In a first step (1300), a word representing a full time slot of data is read from a desired source time slot. In a following step (1302), the aforementioned word is masked to enable only the desired bits which are to be output. Thereafter, in a step (1304), the masked word is rotated to ensure that the target bits are in the correct bit positions for a target time slot, to which the masked and rotated word is written in a step (1306). This cross-connection method supports efficient use of cross-connection control memory, and of buffer RAM memory.
