Cross-connect system and cross-connect method

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 first mapping unit configured to transfer the first signal frames onto common clock signals and map the first signal frames into third signal frames on which cross-connection is performed in the same manner as the first signal frames;
• a second mapping unit configured to transfer the second signal frames onto the common clock signals and map the second signal frames into the third signal frames;
• a selection unit configured to select either the third signal frames output from the first mapping unit or the third signal frames output from the second mapping unit;
• a cross-connection unit configured to receive the third signal frames selected by the selection unit and the common clock signals and perform cross-connection for the received third signal frames;
• a first demapping unit configured to demap the third signal frames output from the cross-connection unit into the first signal frames and output the first signal frames;
• and
• a second 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,
• wherein the cross-connection for the first signal frames is performed with a space switch and a time switch,
• wherein the cross-connection for the second signal frames is performed with the space switch.

A cross-connect method for performing cross-connection for first signal frames and cross-connection for second signal frames, the cross-connect method comprising:

• mapping the second signal frames into third signal frames on which cross-connection is performed in the same manner as the first signal frames;
• selecting either the first signal frames and clock signals of the first signal frames or the third signal frames and clock signals of the third signal frames;
• receiving either the first signal frames and the clock signals of the first signal frames or the third signal frames and the clock signals of the third signal frames selected at the selecting and performing cross-connection for either the first signal frames or the third signal frames;
• and
• demapping the third signal frames that have been cross-connected into the second signal frames and outputting the second signal frames,
• wherein the cross-connection for the first signal frames is performed with a space switch and a time switch,
• wherein the cross-connection for the second signal frames is performed with the space switch.
