USRobotics 1.012.0296-E 96385 56K 8 Bit Isa Modem 00096385 Rev. B00

Product Description

The USRobotics 1.012.0296-E, also identified by its model number 96385 and revision B00, is an internal modem designed specifically for legacy computer systems equipped with an 8-bit ISA (Industry Standard Architecture) expansion slot. This makes it suitable for older PCs and industrial systems where PCI or other modern interfaces are not available. The modem provides essential dial-up connectivity, allowing these systems to connect to telephone networks for data transmission and internet access. This ISA modem card supports the V.90 standard, which was the final ITU-T standard for 56K modems, offering the highest possible downstream data rates over analog phone lines. While downstream speeds could reach up to 56 Kbps, upstream speeds were typically limited to 33.6 Kbps. The card incorporates robust error correction protocols, including V.42bis and MNP 5, to ensure reliable data transfer by minimizing errors and maximizing effective throughput through data compression. These features were critical for maintaining stable connections over potentially noisy phone lines. Installation involves physically inserting the card into an available 8-bit ISA slot on the motherboard and connecting it to a standard RJ-11 telephone line. The 8-bit interface signifies its compatibility with older motherboard designs, often found in systems from the late 1980s through the mid-1990s. The USRobotics 1.012.0296-E serves as a vital component for maintaining or upgrading communication capabilities on vintage hardware, enabling access to networks and data resources that might otherwise be inaccessible.
