ABSTRACT:
A switching system for handling a plurality of cells, each cell including a header section and a data section, and for exchanging a communication message contained in the data section of the cell between a plurality of incoming highways and a plurality of outgoing highways according to the data contained in the header section of the cell. The switching system includes a unit for multiplexing the incoming highways in time division, a first memory having addressable storage locations for storing cells received from the multiplexing unit, a unit for demultiplexing and distributing data output from the first memory among a plurality of outgoing highways, a second memory for storing an empty address of an empty storage location of the first memory, a unit for controlling the write and read operations of the first memory in accordance with an empty address stored in the second memory used as write and read addresses, and a unit for detecting an error in at least one of the write address and read address.
