IBM 93F1574 V.32 9600B Internal Modem

Product Description

The IBM 93F1574 is an internal modem that operates at a data transfer rate of 9600 bits per second (bps), adhering to the V.32 communication standard. This standard, developed by the ITU-T, was a significant advancement in modem technology, offering reliable full-duplex communication over standard analog telephone lines at speeds up to 9600 bps. The 'internal' designation implies that this modem was designed to be installed directly into an expansion slot (such as ISA or PCI) within an IBM computer system. This modem would have been used for various data communication tasks, including remote access to mainframes or servers, establishing point-to-point connections between computers, or connecting to early online services and bulletin board systems (BBS). In its time, 9600 bps was considered a relatively high speed for modems, providing a substantial improvement over earlier 2400 bps or 1200 bps devices. As a product from IBM, the 93F1574 was likely engineered for compatibility and reliability within the IBM hardware ecosystem. Its presence indicates a need for direct data communication capabilities within the computer itself, rather than relying on external modem devices. This component represents a piece of IBM's history in providing integrated communication solutions for its computing platforms.
