com CUBIT Device CellBus Bus Switch TXC-05801 DATA SHEET FEATURES DESCRIPTION • UTOPIA or ALI-25 physical-layer cell interface CUBIT is a single-chip solution for implementing low-cost ATM multiplexing and switching systems, • Inlet-side address translation and routing header based on the CellBus bus architecture.
Such systems insertion, using external SRAM are constructed from a number of CUBIT devices, all • Programmable OAM cell routing interconnected by a 37-line common bus, the CellBus • CellBus bus access request, grant reception and bus.
When operating at a 38 MHz clock rate, a CellBus bus transmission bus system can handle 1 Gbit/s of net ATM cell band• CellBus bus cell reception and address recogniwidth.
CUBIT supports unicast and multicast transfers, tion and has all necessary functions for implementing a • Outlet cell queuing: various modes switch: inlet queuing, cell address translation, cell routing, and outlet cell queuing.
• Ability to insert GFC field in real time • Ability to insert FECN indication, under programmable conditions • Support for ABR-type traffic with minimal cell loss • Ability to send and receive cells for control purposes over same CellBus bus • Cell insertion and extraction via microprocessor port APPLICATIONS • Master bus arbiter included in each CUBIT • Internal GTL transceivers for CellBus bus connecDataSheet4U.
