The invention relates to an ATM telecommunication switch for switching telecommunication connections, said telecommunication switch comprising incoming lines (304, 305), outgoing lines (330, 331), and a switching field (301) for switching any connection from an incoming line to a desired outgoing line, said switching field comprising inputs (306-309) for supplying connections to said switching field, and outputs (310-313) for supplying connections out of said switching field. The telecommunication switch of the invention is characterized in that it comprises a pre-selector (302) provided between said incoming lines (304, 305) and said inputs (306-309) for connecting a desired incoming line of said telecommunication switch to a desired input (306-309) of the switching field (301). |
