IBM 55H6760 ISA Auto Wake Token Ring Adapter

Product Description

The IBM 55H6760 ISA Auto Wake Token Ring Adapter represents a crucial component for integrating legacy IBM personal computers and workstations into Token Ring local area networks. This adapter leverages the Industry Standard Architecture (ISA) bus, a common interface in older PC architectures, ensuring compatibility with a wide range of systems from that era. Its primary function is to provide the necessary hardware and firmware to enable communication over a Token Ring network topology, a popular networking standard before the widespread adoption of Ethernet. This adapter is engineered to handle the specific protocols and signaling methods inherent to Token Ring networks. It likely includes dedicated circuitry for managing the token passing mechanism, frame transmission and reception, and error detection specific to the Token Ring standard. The 'Auto Wake' feature suggests an ability to wake up a connected system from a low-power state, a capability that could be utilized for network-initiated operations or remote management tasks, enhancing the utility and efficiency of the connected device within the network environment. As a specialized piece of networking hardware, the 55H6760 would have been essential for organizations that standardized on IBM hardware and Token Ring networking. Its inclusion in a technical catalog highlights the need to support and maintain existing infrastructure, even as newer technologies emerge. The adapter's design would have focused on reliability and performance within the constraints of the ISA bus and Token Ring protocols, making it a vital link for data exchange and resource sharing in its intended operational context.
