Manufactured Date
Context Function
A desktop office machine that combines the voice communication function of a telephone with the data reception capabilities of a computer terminal.
Context Technical
The Displayphone was marketed as an advanced intelligent terminal aimed at the business market. It was designed to simplify the office space by combining the computer terminal and telephone and minimizing the amount of desk top occupied. It combined the voice communication function of a telephone with the data reception capabilities of a computer terminal & allowed both functions to be used simultaneously. Users could dial unit to unit or to a host computer. Envoy, an email-like application, could be accessed with this equipment. The connections of this device indicate that the telephone & computer elements were completely independent & were merely housed in the same unit. It was connected to the switched telephone network by two standard lines & included a telephone handset, a small video screen, a hide-away keyboard & a built-in modem (Ref. 2).
Context Canada
A Canadian designed & manufactured product. The Canadian company Bell Northern Research developed the concept of the Displayphone for Bell Canada; Northern Telecom subsequently designed and developed the Displayphone product. In 1981 Bell Canada conducted a market trial centred largely in Toronto, Ottawa & Montreal; Northern Telecom provided internal trial for users in the U.S.A. & Canada (Ref. 2). This example appears to have been used at one time by the Government of Canada in its Communications Canada dept. (see markings).
