Transmission features of transcontinental telephony

J. E. Heller: It might be of interest to point out some applications in the West of the developments described by Mr. Jacobs. The longest circuits in the West include those from San Francisco to Seattle, Denver and Salt Lake City. The Seattle circuits are about 950 mi. in length and are made up of carrier channels to Portland, open wire from Portland to Tacoma and cable from Tacoma to Seattle. A large portion of the toll-circuit relief during 1927 in the Pacific System will be cared for by means of about 10 telephone carrier systems. In the next few weeks an additional circuit consisting of 104 wires will be established between Salt Lake City and San Francisco. This circuit, from a service standpoint, will be practically equivalent to the 165 circuits between San Francisco and Chicago.
