MONITORING SET, TELEPHONE AN/GTA-13 (XE-2) SERVICE TEST MODEL
Abstract
The Monitoring Set, Telephone, AN/GTA-13, monitors any voice-frequency land line by means of a two-wire connection to a standard switchboard. As many as fifteen lines may be monitored simultaneously. Provision is made for automatic tape recorder control, and a seven-digit dialed number can be recorded and displayed. Electrical circuits are transistorized. A battery or ac power source may be used. A study made on the tentative breadboard design indicated a reliability which more than meets specifications. Details of basic system requirements, the reliability study, circuit design and development, and mechanical design features are discussed. Typical electrical performance data also are included.
