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’s 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.

Physical layout constraints limit the number of ports that can be connected to a single line card and the number of line cards that can be put in a single shelf. However, by providing the ability to switch between multiple CellBus shelves it is feasible to effectively extend the number of ports in the system to include all of the ports on all of the shelves, thereby increasing the port density of the system, as shown in the diagram above. This is a more cost effective solution than using an edge switch with OC-12 interfaces.
