Development of the NORTHERN ELECTRIC C2 CENTURION Payphone
| The Northern Electric (later Northern Telecom) Centurion was a single-slot electromechanical payphone manufactured approximately from the mid-1970s through the mid-1980s. It represented Canada’s principal transition from earlier three-slot electro-mechanical paystations to a modernized single-slot platform. An example photographed in September 2006 in Sidney, Ohio, was installed at the then Holiday Inn (now Days Inn). Centurions featured interchangeable molded plastic front covers. The most common colour was brown, which was the standard Bell Canada issue, though black, green, and blue variants were also produced. Early production units were equipped with rotary dials, while later versions adopted Touch-Tone (DTMF) keypads as tone signalling became standard. The single front coin slot accepted 5¢, 10¢, and 25¢ denominations. A front-mounted coin return button was provided. Earlier units display the “Northern Electric” logo on the coin hopper door. Following the corporate renaming in 1976, later examples bear the “Northern Telecom” branding. Versions manufactured for the United States were configured for compatibility with the Bell System dual-frequency ACTS (Automatic Coin Toll Service) signalling system. Canadian versions originally operated using single-frequency signalling but were later modified in some regions to dual-tone systems. Canadian Centurions accepted both Canadian and U.S. coinage. It is not confirmed whether U.S.-configured versions accepted Canadian coins. Centurions were manufactured for the United States market, but in significantly smaller numbers than Western Electric payphones used within the Bell System. They were supplied primarily to independent telephone companies, including United Telephone (later Sprint, Embarq, and CenturyLink) and other non-Bell regional carriers. Within Bell System territories, Western Electric equipment remained dominant, limiting Northern Telecom’s penetration. There is no evidence that the Centurion was directly copied by other manufacturers. However, its single-slot, modular plastic-front design reflected broader 1970s industry trends toward simplified, maintainable, and ACTS-compatible payphones, representing convergent evolution rather than imitation. Centurions were widely deployed across Canada by Bell Canada, TELUS/AGT, MTS, Téléphone Milot, and various independent carriers. In the United States, they were used by CenturyLink (formerly United Telephone, Sprint, and Embarq) and a number of other independent telephone companies. |
