IBM 41H9100 25Mbps ATM Adapter for 2210 Nways

Product Description

The IBM 41H9100 is a specialized network adapter card that facilitates Asynchronous Transfer Mode (ATM) connectivity at a speed of 25 Megabits per second (Mbps). This adapter is specifically designed to integrate with the IBM 2210 Nways platform, which was a series of networking hardware used for building wide area networks (WANs) and connecting to carrier services. ATM technology segments data into fixed-size cells, allowing for efficient multiplexing of different types of traffic, including voice, video, and data, over a single network infrastructure. The 25 Mbps speed offered by the 41H9100 adapter was considered high-speed for WAN connections during the era when ATM was prevalent. It enabled organizations to establish robust links to their branch offices or connect to Internet Service Providers (ISPs) that offered ATM-based services. The adapter would handle the complex process of encapsulating data into ATM cells, transmitting them over the network, and reassembling them at the receiving end. As ATM technology has largely been replaced by more modern and cost-effective solutions like MPLS and Ethernet-based WAN services, the IBM 41H9100 represents a component of legacy networking infrastructure. However, for organizations still operating systems that rely on ATM connectivity or requiring access to historical data residing on such networks, this adapter remains a critical piece of hardware. Its function was to bridge the gap between the IBM 2210 Nways system and the broader ATM network, ensuring reliable data transport for business-critical applications.
