USRobotics USR5670 56kb/s PCI Fax Modem

Product Description

The USRobotics USR5670 is a legacy data and fax modem that connects to a computer's PCI slot, offering a pathway to analog communication networks. With a maximum download speed of 56 kilobits per second, it was a common solution for home and small office users needing to send and receive faxes or access dial-up internet services before the widespread adoption of broadband. The PCI interface ensures a direct connection to the motherboard, providing stable performance for its intended use. This modem supports the V.92 and V.90 modem standards, which were the highest speeds achievable over standard analog telephone lines. It features an RJ-11 connector for plugging into a standard phone line. The primary function is fax transmission and reception, but it also allows for dial-up data connections, making it versatile for environments where digital connectivity is not available or as a backup communication method. Installation of the USR5670 typically involves inserting the card into an available PCI slot on the computer's motherboard and installing the appropriate drivers. While largely superseded by modern networking technologies, these modems can still be useful for specific legacy applications, archival purposes, or in remote locations that only have analog phone service. It represents a reliable, albeit slower, method of communication for its era.
