Paradyne 2151-DA2 Acculink 3160 External Modem

Product Description

The Paradyne 2151-DA2 Acculink is an external modem that provides data transmission capabilities over standard analog telephone lines. This device operates at speeds up to 2400 bits per second (bps) using the V.22bis standard, making it suitable for applications that required more bandwidth than earlier 1200 or 300 bps modems but predated the widespread adoption of higher-speed technologies. It connects to a computer via an RS-232 serial port and to the phone network via an RJ-11 connector. This modem is designed for asynchronous communication, a common method for serial data transfer where each character is framed with start and stop bits. It supports a range of legacy protocols, including V.22bis, V.22, V.21, and the Bell 212A and Bell 103 standards, ensuring compatibility with a variety of older communication systems and services. The Acculink series was known for providing reliable performance for its time, facilitating remote access and data exchange. The 2151-DA2 is an unmanaged device, meaning it operates with a fixed set of functionalities and does not require complex configuration. It typically features status indicator LEDs for monitoring connection and data activity. As an external unit, it is easy to install and integrate into existing computer setups. This modem is a representative example of the technology used for dial-up data communications in the late 1980s and early 1990s.
