The Actiontec MDC AC97 Modem v2132D is an internal modem that connects to a computer via a PCI or PCIe slot and provides dial-up Internet connectivity using the AC'97 audio standard for audio and modem functions. The modem is typically used in environments where broadband connections (e.g., DSL or cable) are unavailable or in legacy systems that still require dial-up networking.

The Windows driver for this modem allows your operating system to communicate with the hardware, enabling you to use it for dial-up internet connections or other communication purposes.
