CROSS-POINT ELEMENT STRUCTURE FOR ATM SWITCH

摘要

PURPOSE: A cross-point element structure for an ATM(Asynchronous Transfer Node) switch is provided to implement a switch having a self-routing function, remove necessity of an additional function for copying a cell, and prevent a time slot from being wasted when the cell is copied. CONSTITUTION: Output-group address inputs(AGN(15:0)) represent the output port grouping address information inputted from an external output address allocation part. Output-group address outputs(AGN(15:0)) are transferred to next switch element via a switch element. A path set status input(SIN) represents a path set status of an upper switch element in the same column. A path set status output(SOUT) informs a path set status output to a lower switch element in the same column. Input-cell address inputs(RGN(15:0)) is received by switch elements. Modification address outputs(MGN(15:0)) transfers the path set status of a switch element to a right switch element. A connection designator(GIN) transmits timing information in order to illustrate a final status.
