<P>PROBLEM TO BE SOLVED: To cross-connect a plurality of signal frames at one cross connect part in a cross connect system. <P>SOLUTION: The cross connect system cross-connects a first signal frame for cross-connecting with a space switch and a time switch, and a second signal frame for cross-connecting with the space switch. The cross connect system has: a mapping part for mapping a third signal frame for cross-connecting the second signal frame with the space switch and the time switch; a selection part for selecting any of the first signal frame and its clock and the third signal frame and its clock; a cross connect part for, supplied with the first frame and its clock or the third frame and its clock selected at the selection part, cross-connecting the first signal or third signal frame; and a demapping part for demapping the third signal frame outputted from the cross connect part to the second signal frame, and outputting it. <P>COPYRIGHT: (C)2012,JPO&INPIT |
