Microwave relay system between Saint John and Halifax

A microwave relay system employing time-division multiplex (TDM) has been constructed to provide toll telephone circuits for the Canadian New Brunswick Telephone Company and the Maritime Telegraph and Telephone Company. This system links Saint John in New Brunswick and Halifax in Nova Scotia via five intermediate unattended repeaters and yields 46 four-wire circuits of toll quality that provide out-of-province connections to Montreal, Toronto, Boston, and New York. This system has been in partial use since December 1952, and the complete system has been in continuous service since December 1954. A description of the radio relay link is given primarily from the systemplanning aspects. Performance figures are outlined.
