DISPOSITIVO PER IL TRATTAMENTO DELLE FUNZIONI ATM

The device for processing ATM functions is able to exchange ATM cells with a physical layer interface and with an interface to the switching network subjecting the cells in ATM format to the header translation by means of suitable accesses to an external transcode memory and a translation memory so as to convert them in proprietary format. The converted cells are than sent to the interface to the switching network. Analogously, the cells are converted from the proprietary format in cells of the ATM format by means of appropriate accesses to a switching memory. The converted cells are than sent to the physical layer interface. The device communicates through interface logics with a block for the control of traffic parameters and with a control microprocessor.
