Product Description
The IBM 85H7229 is a specialized network adapter designed for older IBM computer systems that require connectivity over wide area networks using specific legacy protocols. It features a 32-bit PCI interface, indicating its compatibility with PCI slots found in many server and workstation-class machines from the era it was designed for. The primary function of this adapter is to facilitate communication using Wide Area Connection (WAC) and Synchronous Data Link Control (SDLC) protocols. SDLC is a bit-oriented data link layer protocol often used in point-to-point or multipoint communication, commonly associated with IBM's Systems Network Architecture (SNA). WAC likely refers to a broader category of wide area connectivity solutions that IBM implemented. This adapter would have been crucial for connecting IBM mainframes, AS/400 systems, or other enterprise hardware to remote networks or other IBM systems over leased lines or dedicated WAN links. Given its reliance on WAC and SDLC, the IBM 85H7229 is intended for niche applications and legacy environments where these specific protocols are still in use. It is not a standard Ethernet adapter and requires specialized knowledge and driver support for operation. Its purpose is to bridge older IBM systems into wider networks, often for critical business functions that have not yet been migrated to modern networking standards.
