Description

The AT&T 40AAUS external modem, also known by its part number 406793471, is a communication device operating at a data rate of 2400 bits per second (bps). This speed, while modest by today's standards, was common and sufficient for many data communication tasks during its prime. As an external unit, it connects to a computer's serial port and to the telephone network via an RJ-11 connector. It requires an external power supply, typically an AC adapter, to operate. The modem would feature status LEDs to indicate power, send/receive activity, and connection status. This modem was a workhorse for basic data transfer, remote access, and early online services. Its reliability and compatibility with standard communication protocols made it a popular choice for users needing to connect computers over analog phone lines.
