Abstract: It is an object of the present invention to provide switching equipment for communications networks, which switching equipment supports high-speed signalling between switch cards and line cards. Hence, the invention relates to a switching device for communications networks comprising a plurality of line cards and at least one switch card. The line cards comprise connection means arranged on or close to one edge of each line card, and the at least one switch card comprises matching connection means arranged on one flat side of said switch card. In this way, when said switch card is arranged substantially perpendicular to said line cards with said flat side of the switch card facing and at least partially overlapping said edges of the line cards, interconnection is achieved between the connection means of the line cards and the matching connection means of the at least one switch card.
