IBM 21P5289 Multitech PCI 2-Line WAN with V.92 Internal Modem As400

Product Description

The IBM 21P5289 is a specialized communication adapter designed to provide two-line Wide Area Network (WAN) connectivity for IBM AS/400 (now IBM i) systems. This card integrates internal V.92 modems, enabling the AS/400 system to establish dial-up connections over standard analog telephone lines. The V.92 standard represents a significant improvement over previous modem technologies, offering faster download speeds, quicker connect times, and features like modem-on-hold and improved error correction. This adapter connects to the AS/400 system via a PCI (Peripheral Component Interconnect) bus slot, which is a common interface for expansion cards in many computer architectures, including server systems. The dual-line capability allows for simultaneous communication on two separate phone lines, which can be used for increased bandwidth, redundancy, or handling multiple concurrent connections, such as a data call and a fax transmission, or two separate dial-in users. The primary use cases for the IBM 21P5289 include remote data access, dial-in/dial-out capabilities for terminal emulation, fax services, and connecting to remote sites or services that rely on analog modem communication. Its specific design for AS/400 systems ensures compatibility and integration with the IBM i operating environment, making it a crucial component for businesses that require reliable analog communication channels for their legacy or specialized applications running on the AS/400 platform.
