.. CUBIT-Pro Device Cell Bus TM Bus Switch TXC-05802 DATA SHEET Features DESCRIPTION CUBIT-Pro TM is a single-chip solution for implementing - UTOPIA and 16-Bit (ATM or PHY) Layer cell incost effective ATM access systems. It is based on the terfaces Cell Bus TM Bus Architecture (Cell Bus). Such systems are - Inlet-side address translation and routing header constructed from a number of CUBIT-Pro devices, all insertion, using external SRAM of up to 256 k B interconnected by a 37-line mon bus, the Cell Bus - Programmable OAM-cell and RM-cell routing bus. When operating at a 38 MHz clock rate, a Cell Bus - Cell Bus bus access request, grant reception and bus system can handle 1 Gbit/s of net ATM cell bandbus transmission width. CUBIT-Pro supports unicast and multicast trans- Cell Bus bus cell reception and address recognifers, and has all necessary functions for implementing a tion switch: cell address translation, cell routing, and outlet - Outlet cell queuing: various modes cell queuing. - Ability to insert GFC field in real time - Ability to insert FECN indication, under programmable conditions - Ability to send and receive cells for control purposes over same Cell Bus bus - Cell insertion and extraction via microprocessor port - Master bus arbiter and frame pulse generator in APPLICATIONS cluded in each CUBIT-Pro, with enabling pin - x DSL Access Multiplexer - Internal GTL transceivers for Cell Bus bus connec. tion - Remote Access Equipment - Cable Modem Access Multiplexer - Interface port to translation table in SRAM - ATM LAN hub - Microprocessor control port, selectable for Intel - ATM multiplexer/concentrator or Motorola interface - Small-stand-alone ATM switch - +5 V and +3.3 V power supplies - Add-Drop Ring Switch - 208-pin plastic quad flat package - Edge switching equipment Data Shee Translation RAM Address Cell Inlet Data Other Data...
