AT&T 2156-AS2 Acculink 3160 External Modem

Product Description

The AT&T 2156-AS2, identified as the Acculink 3160, is an external modem built for reliable data communication over analog telephone networks. As part of AT&T's Acculink product family, it was engineered to provide stable and efficient connections for businesses and individuals requiring remote access or data exchange capabilities. The external form factor allowed for easy placement and connection without occupying internal computer resources. This modem would have been connected to a computer's serial port (RS-232) and a standard telephone line. It facilitated communication by modulating digital signals from the computer into analog signals suitable for transmission over phone lines, and demodulating incoming analog signals back into digital data. The specific data speed is not detailed in the title, but models in this series typically ranged from 14.4 Kbps to 56 Kbps, depending on the exact version. The Acculink 3160 represents a generation of modems that were essential for accessing online services, sending faxes, and enabling early forms of remote work. Its design prioritized reliability and ease of use, making it a dependable choice for users needing to bridge the gap between their computers and the wider telecommunications network.
