IBM 85H9038 Turboways 25 ATM RJ-45 PCI Card

Product Description

The IBM 85H9038 is an Asynchronous Transfer Mode (ATM) network interface card designed for PCI bus systems. As part of the IBM Turboways 25 product line, it provides 25 Mbps connectivity, enabling high-speed data transfer capabilities for compatible IBM servers and workstations. The card features an RJ-45 connector, indicating its integration with standard Ethernet cabling infrastructure for network connectivity. This card allows systems to participate in ATM networks, a technology that was prevalent for high-performance networking and telecommunications before the widespread adoption of Gigabit Ethernet and other modern standards. ATM networks use fixed-size cells for data transmission, offering advantages in terms of predictable latency and quality of service (QoS), which were crucial for voice, video, and data convergence applications. The IBM 85H9038 serves as a bridge between the ATM network protocol and the host system's PCI bus. It was typically used in enterprise environments or telecommunications infrastructure where ATM was the chosen networking technology for its performance and reliability characteristics. This card represents a specific hardware solution for enabling ATM connectivity in IBM systems of that era.
