Device
DESCRIPTION
The AsTriX
鈩?/div>
(TXC-05840)
CellBus
Expansion Switch is
a single chip switching solution for ATM systems. In order
to meet the accelerating need for bandwidth in access
systems, the AsTriX is designed to allow higher
CellBus
throughput by aggregating multiple
CellBus
shelves
through a switch, and is capable of rates up to 800 Mbit/s
per port. The AsTriX ports support UTOPIA Level 2
interfaces. The switch is non-blocking, incorporating a
backpressure mechanism for eliminating congestion
towards any one port.
The switch may be used to scale a
CellBus
architecture to
deliver up to 9.6 Gbit/s system bandwidth, by connecting
up to 8
CellBus
segments (each capable of 1.2 Gbit/s
switching). A single port (or multiple ports) may be used to
implement an OC-12 uplink in a mux application.
Together with TranSwitch鈥檚 CUBIT, ASPEN and Sertopia
family devices, the AsTriX switch device can be used to
create a cost effective point-to-point serial backplane based
access system.
