1. the method for operation many planes cell switching node, this cell switching node has the first exchange plane, the second exchange plane and a plurality of switching port interface unit;

  • The method comprises;

    By the fault in one of these a plurality of switching port interface units detection the first exchange plane;

    Send a fault detect cell to this second exchange plane from the switching port interface unit that detects;

    In response to receiving this fault detect cell, each from this second exchange plane to these a plurality of switching port interface units sends a plane transformation cell;

    In response to receiving this plane transformation cell, each of these a plurality of switching port interface units is carried out following steps;

    Send cell in order to stop the export business stream from this second exchange plane;

    Start the plane transformation timer;

    Forbid that cell enters into the first exchange plane and the second exchange plane;

    Described plane transformation timer one expiration is just so that cell enters into the second exchange plane;

    The non-professional cell that receives the first predefined type from described the first exchange plane is serial, judges that all professional cells that are assigned to it are cleared out from this first exchange plane;

    Send cell in order to restart the export business stream from this second exchange plane;

    AndTo be redirected to this second exchange plane from this first exchange plane by the Business Stream that enters that these a plurality of switching port interface units send.
