Product Description
The Rockwell V1456VQH-R5 is an internal modem card designed to be installed directly into the ISA (Industry Standard Architecture) slot of a personal computer. This form factor allowed for a clean integration without external boxes or separate power supplies, making it a popular choice for desktop systems during the era of ISA bus dominance. The modem provides essential data and fax communication capabilities, enabling users to connect to bulletin board systems (BBS), early internet services, and send/receive faxes. With a maximum data transfer rate of 14.4 kilobits per second (Kbps), the V1456VQH-R5 offered a respectable performance level for its time. It supported various V.32bis and V.42bis standards, which included error correction and data compression techniques to ensure reliable communication and maximize throughput over analog telephone lines. The integrated fax functionality allowed for sending and receiving documents at speeds up to 9600 bps, adding significant utility for users who needed to exchange documents electronically. Installation typically involved plugging the card into an available ISA slot and connecting a standard RJ-11 telephone line. Software drivers were required for the operating system (such as MS-DOS or early versions of Windows) to recognize and utilize the modem's functions. The Rockwell V1456VQH-R5 was a common component in many pre-built computer systems, providing users with a straightforward and integrated solution for telecommunications.
