The datasheet for the Token Ring Smart Deskstream switch from Madge Networks.

1. Rapid advances in desktop applications are dramatically increasing
the levels of traffic flowing within the LAN workgroup. Token Ring users
must ensure their network infrastructure evolves to meet all future
challenges in a flexible yet cost-effective way by leveraging the existing
investment in Token Ring.
The adoption of switching technology has allowed Token Ring backbones to deliver increased
performance, resilience and scalability to the core of the network. As a natural evolution, Token
Ring switching can be used to provide these benefits throughout the network.
By leveraging the power of installed Token Ring NICs, switched desktop connections can offer
16Mbps (full-duplex) of bandwidth to each PC, and the capability of a high-speed uplink to the
network backbone. This is a dramatic increase in the bandwidth available to users on
conventional, shared-media Token Ring. In addition, dedicated connections eliminate the
likelihood of disruption that rogue PCs can cause on shared rings, improving both manageability
and reliability and therefore reducing support costs.
Madge Networks Smart DeskStream™
Token Ring Switch has been designed to provide the
benefits of full Token Ring switching for direct PC connections, at a price that makes switching
to the desktop the only viable option.

By implementing the latest-generation switching technology, the Smart DeskStream
guarantees support for all current and future application requirements. Being a direct
replacement for existing hubs, the Smart DeskStream will use currently installed Token Ring
adapters, cabling and racking, avoiding the need for further investment. Designed to be HSTR
and multi-service ready, the Smart DeskStream is an ideal platform for supporting the emerging
standards in Token Ring networking, while Year 2000-compliance provides network managers
with full peace of mind.

Madge’s Smart DeskStream employs high speed, low latency cut-through switching to deliver
wire-speed bandwidth to every desk, optimizing network-application performance. The highly
scaleable stacking architecture offers simple, gradual expansion as additional network connections
are required. This means Smart DeskStream can provide a port density of up to 192 ports in a
single device, improving ease of management and reducing rack space requirements.
The Smart DeskStream TR Fiber Module allows easy connection in Fiber-oriented networks,
whilst HSTR modules increase the available bandwidth for workgroup connections to network
backbone resources.

With auto-speed and media sensing ports and support for both Source Route and Transparent
forwarding techniques, the Smart DeskStream allows PCs to be instantly upgraded from shared
to switched connections without needing re-configuration. Alternatively, the Smart DeskStream
master port supports the connection of the existing shared hub, introducing an additional 23 ports
for high-speed desktop connections.
Combining advanced ease of use functionality with exceptional performance,
the Smart DeskStream Token Ring Switch signifies the arrival of true, desktop
switching for Token Ring users.
