Intelligent Ethernet segment switch expands Allied Telesyn's 3600 line of hubs; AT-3724TR provides 8,000 MAC address capability.

SUNNYVALE, Calif.--(BUSINESS WIRE)--July 25, 1995--Allied Telesyn International Corp. announced Tuesday the availability of the AT-3724TR, a standalone Ethernet switch that provides a central point of connectivity for Allied-Telesyn's 3600 series of stackable hubs.

Equipped with 24 switched 10BASE-T ports and capable of storing more than 8,000 media-access control (MAC) addresses, it is designed for segment switching for small- to medium-sized networks. In combination with the 3600 stacks and an upcoming segmented backplane, the AT-3724TR is one of the most cost-effective switched workgroup solutions in the marketplace. The switch is backwards compatible with the entire 3600 series of hubs.

The AT-3724TR utilizes twin RISC-based processors to increase performance by isolating and assigning switching tasks and management tasks to separate processors. It also includes a store and forward architecture to improve LAN and data integrity, and supports the IEEE 802.1 Spanning Tree protocol to eliminate endless network loops.

"The 3724 gives users a direct migration path to switched environments using their current 3600 series hubs," said Anders Swahn, senior vice president, marketing, Allied Telesyn. "Using the 3724 in conjunction with the 3600 hubs in a switched environment allows the network manager to view up to eight segmented hubs as a single icon on the SNMP console, clearing up much of the clutter that micro-segmentation has created on net management."

Features

The AT-3724TR provides backbone connectivity for the 3600 series hubs. Each of the 24 ports acts as an independent Ethernet segment providing 10 Mbps of bandwidth per segment. A port-trunking feature allows up to eight ports to be grouped together to increase bandwidth to 80 Mbps between 3724 switches; the switch supports multiple trunk groups. Other features include:

* MAC Addresses - provides flexible application connections ranging from single workstations to multi-station segments based on its ability to support more than 8,000 MAC addresses.

* Store and Forward - ensures network and data integrity by identifying and preventing packet transmission errors from being propagated throughout the network; also buffers packets until network resources are available.

* Filtering - utilizes user-defined filtering to allow the LAN manager to define the criteria by which packets will be screened by either bridge address table filters or port filters; filtering gathers statistics on a per-port basis, by MAC address or for the entire switch.

* IEEE 802.1d Spanning Tree Algorithm - identifies redundant paths between spanning tree bridges to eliminate endless loops and designates one path as the primary path and assigns another as the secondary path to be activated in event of primary path failure.

* Network Management - includes built-in SNMP management and Telnet capability; will be supported by the entire line of AT-VIEW management tools; also supports MIB II, 802.Id, 802.3m, and any SNMP-based network management system.

Availability and Pricing

The AT-3724TR is immediately available in both 110V and 220V versions for domestic and international markets. It is FFC A-, TUV-, CSA-, and UL-compliant. The suggested retail price for the AT-3724TR is U.S. $10,445.

Company Background

Incorporated in 1987, Allied Telesyn International Corp. (ATI) is a leading supplier of Ethernet products for local area networks (LANs). The industry's largest supplier of Ethernet media products such as transceivers and micro repeaters, ATI entered the market for interface cards and hubs in 1992. The company provides a component based "building block" approach to designing and implementing LANs. Revenues for ATI and its affiliates exceeded $180 million in 1994.

The company has development and manufacturing facilities in the U.S. and the Pacific Rim, including IC design capability that allows it to offer highly cost-effective and reliable products in the fast growing LAN market. ATI has affiliates in Japan, Hong Kong, and Singapore, as well as subsidiaries in the United Kingdom, Canada, France, Germany, Italy and the Netherlands.
