The TSX-1620 is a high-speed stand-alone Token Ring switch with the ability to transparently switch packets among its various attached ring networks at full line rate (4 or 16 Mbps) and with minimal latency. The TSX-1620 provides source routing functions while using store and forward switching technology. The TSX- 1620 also provides virtual networking capability, allowing you to configure logical rings that include multiple physical rings attached to the front panel ports (e.g., physical rings inserted in ports 1, 2, 5, and 8 could all be assigned to a single virtual ring network, and would communicate as if they actually were on the same physical ring). Using this capability, 4 and 16 Mbps devices can be placed on separate physical rings (each port automatically determines the speed of the ring to which it is connected), allowing the 16 Mbps devices to operate at full speed, and the switch can treat both rings as a single logical ring network. Broadcast discovery packets can be confined to a virtual subset of the attached rings, thereby reducing overall traffic on the switch.

The TSX-1620 is an 8 port switch which is expandable to 16 ports, with STP/UTP and 4 or 16 Mbps on each port via front panel RJ-45 connectors. The device is IEEE 802.5 compliant with support for IEEE 802.1d spanning tree, and supports SNMP, including MIB II.

Using the TSX-1620 User’s Guide

Your SPECTRUM Portable Management Application (SPMA) for the TSX-1620 consists of a number of different applications, each of which provides a portion of the overall management functionality. Each of these applications can be accessed from the icon menu (if you are using a management platform) and from the Stand-alone Launcher or the command line (if you are running in stand-alone

TSX-1620 specifications

The Cabletron Systems TSX-1620 is a pioneering piece of network hardware that played a significant role in the evolution of networking technologies during the 1990s. This well-engineered device is primarily recognized as a multi-port Ethernet switch that was designed to provide high-speed, reliable connectivity for local area networks (LANs). As organizations increasingly demanded robust performance and enhanced network capabilities, the TSX-1620 emerged as a powerful solution to address these needs.

One of the key features of the TSX-1620 is its support for both 10Base-T and 100Base-T standards, catering to both standard Ethernet and Fast Ethernet connections. This versatility allowed businesses to easily transition from older Ethernet systems to newer, faster specifications without replacing their entire infrastructure. The switch could intelligently manage traffic between devices, minimizing collisions and ensuring that data packets were transmitted efficiently.

The architecture of the TSX-1620 includes support for various advanced technologies that enhance network performance. Its store-and-forward switching capability improves data integrity by checking packets for errors before forwarding them to their destination. This process reduces the risk of corrupted data affecting network performance, making it especially valuable for mission-critical applications.

Another notable feature is its robust security tools. The TSX-1620 incorporates VLAN (Virtual Local Area Network) support, enabling network administrators to segment traffic and improve security across different departments or user groups. This not only mitigates the risk associated with unauthorized access but also optimizes network traffic by confining broadcasts to designated VLANs.

Scalability is a prominent characteristic of the TSX-1620. With ports available for expansion, organizations could easily increase their network capacity as their needs grew. This feature promoted long-term investment in network infrastructure, allowing businesses to adapt quickly to changing demands without incurring substantial costs.

Reliability is paramount in networking equipment, and the TSX-1620 does not disappoint. Engineered with high-quality components, this switch was built to operate efficiently in a variety of environments while maintaining stable performance. Its design ensures a cooling mechanism that minimizes overheating, thereby prolonging its operational lifespan.

In summary, the Cabletron Systems TSX-1620 represents a significant advancement in network switch technology during its era. Its combination of speed, versatility, security features, and robust architecture made it a valuable asset for organizations seeking to enhance their networking capabilities and prepare for the future.
