Mountain View, California-headquartered Allied Telesyn International has filled out the high-end of its Ethernet switching range (CI No 2,634) with the new Simple Network Management Protocol-compliant 24-port AT-424TR. The product is said to use twin RISC-based processors in a combined hardware and software switching architecture and to use a non-blocking store and forward architecture with buffered switching. Support for the IEEE’s 802.1d Spanning Tree Protocol is also claimed, as are port grouping capabilities, enabling up to eight 10Mbps segments to be combined to form 80Mbps paths between switches. No news yet on pricing or availability. The company has also announced a new family of Ethernet adaptor boards for PCI-based personal computers. The boards ship with an Simple Network Management Protocol agent included and come in four configurations for different cabling types: 10Base-T; 10Base-5 A UI; 10Base-2 BNC and 10Base-T; and 10Base TL/ST and 10Base-T. Again, no word on availability or on pricing.
