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. The acoustic coupler predated modems. An early example is the Anderson Jacobsen ADC 212 Acoustic Data Coupler. Our model is mounted in a wooden case. It has a serial number of 222 and was designed for use in the UK Our coupler was kindly donated by Jeremy Wilcox. Date : 1965Manufacturer : Anderson Jacob This exhibit has a reference ID of CH6459.
