Applications
The 3Com 3CP2976-OEM-50 is a late-1990s/early-2000s internal dial-up modem designed for desktop PCs running Windows 95, 98, ME, 2000, or XP. Cards like this were the standard method for residential and small-office dial-up internet access during the pre-broadband era, connecting to the public switched telephone network (PSTN) over standard analog phone lines at up to 56 Kbps under the V.90 standard. The voice capability allowed the card to handle answering-machine functions, caller ID, and speakerphone applications through bundled software. The RJ-11 line and phone pass-through ports let a telephone handset share the same wall jack. Today these cards are primarily sought for legacy Windows systems, retro computing setups, industrial equipment with dial-up remote access requirements, or applications still dependent on analog POTS lines such as fax machines and alarm systems. The 3CP2976-OEM-50 OEM designation indicates it was supplied through system integrators or OEM PC builders rather than retail channels.
This 3Com 3CP2976-OEM-50 56Kbps Voice PCI Modem Card has been pulled from a working environment where it was previously in use. The card itself is in good used condition — the PCB and components are intact with no visible damage. The metal bracket shows surface rust and corrosion, as visible in the photos. The card includes dual RJ-11 ports and two 3.5mm audio jacks. Please review all photos for a complete look at the card's condition, and contact us if you have any questions.
