Product Description
The Compaq 157071-B21 is a legacy internal modem designed to add data and fax communication capabilities to desktop computers. Utilizing the PCI bus for integration, this card provides a reliable method for establishing connections over traditional analog telephone lines. With a maximum data transfer rate of 56Kb/s, it was a standard for dial-up internet access during its era. Beyond internet connectivity, the modem also supports fax functionality, allowing users to send and receive faxes directly from their computers. This dual functionality made it a versatile peripheral for small businesses and home users. The card features an RJ-11 connector for plugging in a standard telephone cord, enabling communication with other modems or fax machines. Its installation typically requires an available PCI slot on the computer's motherboard and the installation of appropriate drivers.
