Product Description
The Rockwell PN311 is an internal modem card designed for the 8-bit ISA (Industry Standard Architecture) bus, making it compatible with a wide range of older personal computers. The 'V.34i' designation indicates that this modem supports the ITU-T V.34 standard, which allows for data transmission speeds of up to 28.8 kilobits per second (Kbps), a significant advancement over earlier modem technologies. The 'i' suffix might denote an integrated or specific implementation of the V.34 standard. A key feature of the PN311 is the inclusion of jumpers. These physical switches on the circuit board allow users or system integrators to manually configure hardware settings such as the modem's I/O address and IRQ (Interrupt Request) line. This manual configuration was common for ISA devices and was necessary to ensure the modem could communicate effectively with the computer's CPU without conflicting with other installed hardware. This modem card would have been used for various communication tasks, including dial-up internet access, remote network access, and sending or receiving fax documents. Its 8-bit ISA interface ensured broad compatibility with the PC and PC/AT compatible systems prevalent during the era when V.34 modems were cutting-edge technology. The PN311 provided a vital link for data exchange in a time before widespread broadband adoption.
