Patent ID: 8780897

Claim:
A cross-connect system for performing cross-connection for first signal frames and cross-connection for second signal frames, the cross-connect system comprising: a cross-connection unit including a space switch and a time switch and configured to perform cross-connection for signal frames using both of the space switch and the time switch, wherein the first signal frames have a first clock frequency and are a type of signal frames for which cross-connection is performed using the time switch and the space switch, and the second signal frames are a type of signal frames for which cross-connection is performed using only the space switch; a mapping unit configured to map the second signal frames into third signal frames that have a second clock frequency different from the first clock frequency and for which cross-connection is performed using the time switch and the space switch; and a selection unit configured to select one of a combination of the first signal frames and clock signals with the first clock frequency and a combination of the third signal frames and clock signals with the second clock frequency and to supply the selected combination to the cross-connection unit, wherein the cross-connection unit is configured to perform cross-connection for one of the first signal frames and the third signal frames selected by the selection unit by using both of the space switch and the time switch; and a demapping unit configured to demap the third signal frames output from the cross-connection unit into the second signal frames and output the second signal frames.
