Dell PCI Data Fax Modem

The Dell RD01-D850 is a PCI data fax modem designed for desktop computers. It provides a 56K V.92 connection for dial-up internet access and fax transmission. The card uses a Conexant chipset and is supplied as a new OEM component without retail packaging.

Suited for legacy dial-up needs

This modem suits users maintaining older Dell desktops that require a hardware PCI modem for dial-up connectivity or fax services. It is not for systems lacking a free PCI slot or for anyone needing broadband, Ethernet or wireless networking capabilities.

56K V.92 throughput ceiling

The V.92 standard delivers up to 56 kilobits per second downstream under ideal line conditions. Real-world speeds are typically lower due to line noise and distance from the exchange. The modem cannot exceed this bandwidth ceiling and offers no headroom for modern internet applications.
