520 _a"Telephone troubles : Their location and remedy by Edward Mahon Wev" is a practical technical manual written in the early 20th century. Aimed at telephone installers and repairmen, it focuses on locating and fixing faults in subscriber sets and switchboards, explaining the behavior of ringers, transmitters, receivers, induction coils, condensers, hooks, cords, grounds, and wiring. The book proceeds from single direct-line sets to two-party and four-party instruments, then to private-branch-exchange switchboards, showing how to diagnose symptoms like silent or weak bells, steady bridges, dead receivers, poor transmission, and cross-talk. It teaches systematic tests with a head receiver and test lamp, short-circuiting condensers, isolating cords and coil windings, checking polarity and reversals, assessing grounds and earth currents, and adjusting ringers and relays. The switchboard section covers stuck or non-operating drops, battery-feed and trunk poling, cord-circuit opens and shorts, relay and holding-coil checks, and causes of inadvertent ringing. It closes with clear inspection routines for subscriber stations and new installations, emphasizing neat wiring, solid connections, correct protection, and reliable operation.
