An acoustic coupler is a device that allows a computer to transmit data over a standard telephone line by converting digital signals into audible tones and sending them through a telephone handset's speaker and microphone. The coupler physically holds the handset in rubber cups to minimise background noise and ensure sound transmission. Anderson Jacobson was primarily a manufacturer of acoustic coupler modems, but also manufactured printing terminals designed to replace teletypes. Anderson Jacobson began early in 1967 as a manufacturer of one of the first acoustic data couplers. By 1973, the company had acoustic coupler products that transmitted at 150, 300, 450 and 1200 baud. Our Anderson Jacobson A211 Acoustic Coupler has a serial number of 30783 and was kindly donated by William H L Williams.
