Abridgment of long telephone lines in Canada

This paper describes the development of the long distance telephone service in Canada, historically, from its inception and the installation of the nucleus of 360 mi., up to and through the present status and lines listed in Table I, to the proposed development represented by Table II, the result of a careful study of calls per day to be expected by 1932. This effort is to provide for traffic requirements in a manner most suitable from a transmission point of view, and to accomplish it with a minimum amount of switching. Much of the engineering work for this is already actively under way and certain work of construction actually commenced. A survey of existing routes and the matter of transmission maintenance discussed.
