Abstract
An ATM telecommunications switch includes a plurality of parallel data switching planes and a parallel control plane, each plane having an equal number of input ports and output ports and a central switching unit to switch each input port to any output port. Data from a single timeslot on the central switching unit is connected to a plurality of output ports in a point to multipoint operation. A multipoint memory stores information regarding the data addresses and a forward transfer store provides additional storage for multipoint cells.
