Patent ID: 7009975

Claim:
Telecommunication switching arrangement ( 1 ) for switching digital data contained in data packets ( 23 ) provided with a packet header ( 21 ), which contains a first ( 25 ) and a second index ( 26 ) representative of a first and a second priority characteristic of the data packet ( 23 ), the arrangement ( 1 ) comprising a crosspoint switch ( 3 ) for switching packets ( 23 ) from a plurality of input lines ( 5 , 7 ) of the switch ( 1 ) to an output line ( 11 ) of the switch ( 1 ), and a sequencer in the crosspoint switch ( 3 ) for determining a sequence in which the data packets ( 23 ) are to be switched to the output line ( 11 ), and a storage ( 5 ) for temporarily storing the data packets ( 23 ), characterized in that the sequencer is operative to determine the sequence in which the data packets ( 23 ) are to be switched to the output line ( 11 ) based on a result of a mathematical operation on the first index ( 25 ) and the second index ( 26 ).
