IBM 87H3464 X.25 Interface PCI Coprocessor. PCI form factor adapter card designed to add X.25 wide-area network (WAN) connectivity to IBM systems and compatible platforms. Implements X.25 packet switching protocol offload, reducing CPU overhead for remote data communications. Typically deployed in legacy IBM enterprise servers and workstations requiring dedicated WAN interface capabilities for frame relay, packet switching, or point-to-point serial communications. Compatible with standard PCI slots; assembly of mounting bracket or chassis integration may be required depending on installation environment. Suitable for maintaining or expanding existing X.25 network infrastructure in financial services, telecommunications, or enterprise computing environments where legacy WAN protocols remain in operational use.
