Telephone engineering

Proceedings of the American Institute of Electrical Engineers, 1906

Engineering may broadly be divided into two classes, civil and military. Military engineering is that which pertains to the conduct of war and is sufficiently understood to require no description. Civil engineering, as I am now using the term, comprehends all forms of engineering which are conducted without special reference to the operations of war. Falling within this definition of ...


Transmission characteristics of bell system subscriber loop plant

Transactions of the American Institute of Electrical Engineers, Part I: Communication and Electronics, 1963

This paper discusses some principal results of a recent Bell System subscriber loop survey. Statistically sound estimates of various physical and transmission characteristics of the loop plant are presented. This information is useful in appraising the current transmission properties of the plant in the light of existing requirements. It provides a novel basis for evaluating new developments and services affecting ...


Power system design for fiber to the home systems

IEEE LCS, 1990

The overall topology of the AT&T fiber to the home (FTTH) system is reviewed with particular emphasis on power. The focus is on the issues that arise in powering the customer end of the fiber, i.e., the distant terminal. It is shown that flexible power arrangements are required for distant terminals in the fiber system in the local plant. Architectures ...

A study of multi-office automatic switchboard telephone systems

Proceedings of the American Institute of Electrical Engineers, 1908

This paper treats of three principal topics: 1. The enormous economic waste which the wire, cable, and conduit equipment of a telephone system involves. 2. A recapitulation and discussion of reasons which make this waste necessary or expedient in manually operated systems. 3. How this waste can and should be greatly reduced in systems employing automatic switchboards.

  • Telephone engineering

    Engineering may broadly be divided into two classes, civil and military. Military engineering is that which pertains to the conduct of war and is sufficiently understood to require no description. Civil engineering, as I am now using the term, comprehends all forms of engineering which are conducted without special reference to the operations of war. Falling within this definition of civil engineering we have electrical engineering, mechanical engineering, telegraph engineering, telephone engineering, and some others. As taught in colleges, however, and as generally understood, civil engineering is restricted and deals more especially with that branch of the art which pertains to the construction of bridges, water works, railroads, harbor improvements, and other public works of like character.

    The overall topology of the AT&T fiber to the home (FTTH) system is reviewed with particular emphasis on power. The focus is on the issues that arise in powering the customer end of the fiber, i.e., the distant terminal. It is shown that flexible power arrangements are required for distant terminals in the fiber system in the local plant. Architectures must be able to accommodate local exchange carrier preferences for AC or DC pedestal operation. The system must readily accommodate new as well as existing applications in growth areas and also rehabilitation applications.<<ETX>>

  • The great blue box phone frauds

    The use of an electronic device called the blue box to exploit a loophole in the nation's long-distance telephone network is recounted. To avoid long- distance charges, blue box users first dialed long-distance directory assistance, 800 numbers, or numbers that carried only a small toll charge. After the user dialed his number and was connected to a long-distance trunk, the blue box emitted a 2600 Hz tone, clearing the equipment at the tandem trunk's receiving end and signaling the switching equipment that the call had been completed and the trunk was waiting for a new call. The local central office, however, had not received its call termination signal, so the local central office did not disconnect the caller from the long-distance network. The permanent solution to the blue box problem proved to be common channel interoffice signaling (CCIS), a method rejected in the 1950s as too costly and difficult to implement.<<ETX>>

  • ICs for PCM telecommunications

    IC CODECs for telephone central office, PABX and channel bank applications, will be discussed. Topics include viability of various design approaches, system applications, testing, specification problems and reliability. Secondary discussions will cover active filters and electronic line circuits: 2 to 4 wire conversion and related functions.

  • A modern automatic telephone apparatus

    The writer presented a paper before the annual convention of the Institute in 1908, dealing with automatic telephone equipment from an economic viewpoint.∗ The present paper will therefore be principally devoted to a description of the apparatus used and its method of operation in modern plants. Although there are several different types of automatic telephone equipment upon the market or being developed, practically all of the working plants use apparatus of the “Strowger” type with or without the addition of Keith line switches. Since this paper must be confined to one system, only the one which is extensively used will be discussed. The description will begin with a short reference to the subscriber's station equipment.

  • Traffic studies in automatic-switchboard telephone systems

    The paper describes a telephone traffic recording machine by means of which not only the number of calls for a given period, but also the average duration of each call, is mechanically registered on a moving tape. The observations recorded here were taken on an automatic telephone system. The graphical record shows the exact duration of each connection, the number of connections made during a given interval, and the number of simultaneous connections in service at each instant. By means of these records it is possible to study the relative efficiency of small and large trunk groups, the average holding time of calls, and these observations permit the switches and trunks to be so arranged that the calls will be evenly distributed among the trunks in each group.

  • New transmission test set for exchange-type trunks

    The increased use of carrier systems and 1-way dial circuits has increased the complexity of transmission testing. The introduction of direct-distance dialing has made the transmission maintenance requirements far more stringent. The instrument described here, designated as the Model TTS 6, was developed to cope with the increased complexity, to provide a high degree of accuracy, and to permit the use of labor-saving “1-man” test procedures.
