TL;DR: Pertinent processor architecture features used to achieve ESS reliablity objectives are discussed and a detailed discussion of the maintenance design of the 3A Processor is also included.
Abstract: The stored program control of Bell System Electronic Switching Systems (ESS) has been under development since 1953. During this period, the No. 1 ESS, the No. 2 ESS, and the No. 3 ESS have been developed and used extensively by Bell System operating companies to provide commercial telephone service. These systems serve all types of telephone offices: The large-capacity No. 1 ESS serves metropolitan offices, the medium-capacity No. 2 ESS was designed for suburban offices, and the No. 3 ESS can be found in many small rural offices. The fault tolerant design of ESS processors provides the same highly dependable telephone service established by the previous electro-mechanical systems. Pertinent processor architecture features used to achieve ESS reliablity objectives are discussed. A detailed discussion of the maintenance design of the 3A Processor is also included.

TL;DR: In this paper, a telephone central office switching system with economical application to small community dial office sizes is described, where communication paths are spatially switched over a modular network fabric comprised of electromechanically actuated metallic crosspoints.
Abstract: A telephone central office switching system with economical application to small community dial office sizes is disclosed. Communication paths are spatially switched over a modular network fabric comprised of electromechanically actuated metallic crosspoints. A distributed control concept is employed wherein the logic power and flexibility of electronic stored program control is spread over many points in the system. Serial asynchronous messages between any two control elements are routed via a central information exchange unit whose number of communication ports is easily changed on a pluggable basis. Modularity is emphasized throughout the switching system for facile growth and additions of feature-oriented service packages.

1 Apr 1977TL;DR: In this paper, the authors present a control circuitry for a radio telephone having a transmitter, a receiver, a cradle and a handset, which includes a first computer having a stored program control therein, a first memory, a telephone number display and a pushbutton pad.
Abstract: A control circuitry for a radio telephone having a transmitter, a receiver, a cradle and a handset. The handset includes a first computer having a stored program control therein, a first memory, a telephone number display and a pushbutton pad. The cradle includes a second computer having a stored program control therein, a second memory, a plurality of control switches and radio telephone status indicators. A dialed number is entered into the handset memory from the pushbutton pad, under control of the handset computer. Then during a telephone call, the entered number is transferred from the handset computer to the cradle computer and transmitted by the cradle computer. Frequently called numbers can be stored in the handset memory or the cradle memory and later, can be readily recalled and transmitted. The last dialed number can be automatically retransmitted in a subsequent call.

TL;DR: The authors wish to provide a unification of this issue's papers by providing a clear context for them.
Abstract: The authors wish to provide a unification of this issue's papers by providing a clear context for them. Common channel signaling can be defined as the system that enables stored program control exchanges, network databases, and other nodes of a network to exchange messages related to call setup, supervision, and take down (call and connection control information); information needed for distributed application processing (interprocess query and response or user-to-user data); and network management information. >

TL;DR: In this article, a method and means for providing a remote data station with access to the program memory of a stored program common control telecommunications switching system is presented, where the access is restricted to stations whose telephone numbers are stored in the memory of the switching exchange.
Abstract: A method and means for providing a remote data station with access to the program memory of a stored program common control telecommunications switching system. The control complex has an input/output port and a modem for interfacing that port with its switching network. The control has the capability of setting up connections in the network between the modem and a selected trunk. Incoming connections to the modem are given only limited access to the stored program control, that access for the purpose of analyzing incoming data to detect a predetermined code. In the event the predetermined code is detected, the incoming connection is taken down, and an outgoing connection established to a distant station by dialing the number of an authorized station which is stored in the program memory. Full access to the program memory is then allowed, such that full access is provided only to stations whose telephone numbers are stored in the memory of the switching exchange.
