.. ASPEN Port Expander TXC-05811 DATA SHEET Features - Interoperable with ASPEN (TXC-05810B) UTOPIA Level 2 interface - Provides port expansion for up to 64 UTOPIA Level 2 ports - Utilizes ASPEN ATM Access EDGE firmware for design and field upgrades - Supports unicast and spatial multicast traffic to all 64 ports - Backpressure mechanism to prevent cell loss - ASPEN-PX management integrated with ASPEN via the host mailbox interface - Single +3.3 V power supply - 256-lead Plastic Ball Grid Array (PBGA) package, 17 mm x 17 mm  ASPEN-PX Device DESCRIPTION The ASPEN-PX (TXC-05811), ASPEN Port Expander provides state of the art UTOPIA port expansion capability, increasing ASPEN’s PHY support from 16 to 64 ports with unicast and multicast traffic delivery to enhance system flexibility. Its seamless interface with ASPEN (TXC-05810B) enables customers to increase the system port density of their Cell Bus-based UTOPIA Level 2 platforms, and leverage existing ASPEN hardware and software designs, reducing time-tomarket. All traffic management for the 64 ports is handled directly by ASPEN. Coupled with the ASPEN-PX, ASPEN creates a new value proposition for the industry, particularly in the broadband access market, by extending the Cell Bus architecture to form a distributed processing and switching environment that can directly implement multi-service network functionality for ATM cell-based traffic effectively and efficiently. . - ATM Access Multiplexers - DSLAM Applications - Multi-Service Access Multiplexers - ATM LAN Switch - Vo IP/Vo ATM Voice Gateways - Frame Relay Switch AUCLK To ASPEN UTOPIA Ports (data and control) ADCLK 32k x 32 SRAM To 64 Subscriber UTOPIA Ports ASPEN-PX UTOPIA 2 Port ASPEN Port Expander TXC-05811 UTOPIA 2 Ports Copyright  2003 Tran Switch Corporation Tran Switch, TXC, ASPEN Cell Bus, PHAST are registered trademarks . of Tran Switch Corporation Document Number: PRELIMINARY TXC-05811-MB, Ed. 6...
