Product Description

The AT&T MPX4800 modem operates at a data transfer rate of 4800 Baud, positioning it as a mid-range modem during its operational lifespan. AT&T, a major telecommunications company, produced various modems to facilitate data exchange over analog phone lines. This particular model likely served business and professional users who needed reliable dial-up connectivity for tasks such as remote access, data file transfers, or communication with other offices. The mention of software version 866-M179-0151 suggests that this modem might have required specific drivers or control software to function optimally. This was common for more advanced modems of the era, where firmware updates or specialized software could enhance performance or add features. The MPX4800 would have connected to a computer, typically via a serial port, and to a standard telephone line. At 4800 Baud, the MPX4800 offered a substantial improvement over earlier 1200 or 2400 Baud modems, allowing for quicker transmission of data. It represents a key step in the evolution of modems, bridging the gap towards higher speeds that would eventually lead to broadband internet access. This device was a critical tool for enabling remote work and data sharing in its time.
