1. A digital switch intended for use in a node in a circuit switched telecommunication network with a distributed switching function, the switch comprising: a switch memory, a time slot counter, which is connected to the switch memory and arranged to point out an address therein for cyclical writing in the switch memory of data arriving into the switch, a control memory for controlling an order of data read out from the switch memory, and an adapting device, wherein the switch memory is connected via the adapting device to a transmission medium, which is common to a number of nodes in the network, the time slot counter is connected via the adapting device for receiving frame synchronization from the common transmission medium, the control memory is arranged for selecting time slots from the common transmission medium and for generating a read address to the switch memory, and each of the control memory and the switch memory includes a number of memory cells and an address space that defines a number of addressable cells, the number of the memory cells being less than the number of addressable cells.
