The invention relates to a cross-connect switch for time division multiplexing in a digital communication network, which is disposed to establish connections between a tributary system (TSys) with a first number (m) of tributary system time slots and an aggregate system (ASys) with a second, significantly higher number (n) of aggregate time slots. This includes data storage blocks (DM>UP<, DM>DOWN<) with data cells (DC 0 to DC m-1), which are each definitely associated with a tributary system time slot, to buffer the data words of at least one tributary system frame, and there is access to these data words by means of addresses (A) according to a connection sequence that is a function of call intent, a control memory (CM) with control cells (CC) for storing the addresses (A) of the data cells that are required during the current aggregate frame for the exchange of data words between the data memory (DM) and the aggregate system (ASys). According to the invention, in addition to a data cell (DC x), each tributary system time slot (T-TS x) is also definitely associated with a control cell (CC x), and in the event of a call intent for the tributary system time slot (T-TS x) with an aggregate time slot (A-TS y), a data set is entered into this control cell (CC x), which data set contains the number (A-TS No. = y) of the aggregate time slot (A-TS y) in a first data field (AF x), and contains the address (A>NXT< = z) for the data set of the subsequent connection in a second data field (MF x).
