Public Switched Telephone Network (PSTN)

The PSTN Set of Rules (PSTN SR) contains two volumes.

Volume I – SR on Public Automatic Telephone communication.
Volume II – SR on the future norms on the PSTN channels.

This SR should be used by research and development organizations in development of the switches and nodes of the telephone network, by the network planning organizations during the development of the project and automatization plans, by the Ministry of Communication departments for the development of the telephone networks by the different organizations to interface their private networks with the PSTN.

Some Aspects of Russian Telecommunications

Sokolov N.

IEEE Communications Magazine, vol. 44, No. 1, 2006

Two articles under the same title "Telecommunications in Russia" were published in IEEE Communications Magazine in 1992 and 2000 respectively. From the beginning of this century Russian telecommunications has undergone significant changes. Some of them related to mobile networks and Internet are briefly described in this article.

Telecommunications in Russia

Sokolov N., Goldstein B. IEEE Communications Magazine, August 2000, Vol. 38, No. 8

Eight years ago the article under the title “Telecommunications in Russia” was published in “IEEE Communications Magazine” [1]. In 1995 the feature topic "Telecom technology, systems, and services in Russia and the new republics" had continued the presentation of telecommunication development in Russia. The time passes. National telecommunications underwent significant changes. Some of them are described in this article.

Introduction of Modern Telecommucations Equipment in Russia and New Republics

Goldstein B., Sloutsky L.

IEEE Communications Magazine Vol.33, No.7, July 1995

The former Soviet Union is still a united country in terms of telecommunications (and telephony in particular). Though different countries have gained their independence, the telephone network is still united and built according to the same technical standards and regulations.

In this article we describe the process of introducing new equipment for the telecommunications networks of the former USSR, taking into account our personal experience. First, it is important that we are dealing mainly with local switching, so the examples discussed are mainly from this particular field.

What is Telecommunications in Russia? From the Russian Guest Editors

Boris S. Goldstein, Andrew E. Koucheryavy

IEEE Journal on Selected Areas in Communications, vol. 12, no. 7, 1994

The answer is different in Khabarovsk, Moscow, St. Petersburg and Novosibirsk. The network of the country is rather large, with more than 40 million subscribers on the territory of the former U.S.S.R. in 1991, and united all over the territory. At the same time, the switching equipment is mainly electromechanical using national signaling systems. More than 30% of the existing digital switches are concentrated in Moscow and St. Petersburg, and it is virtually impossible to find them in the small towns on the banks of Volga.

Our aim is to inform the reader about the regulations and circumstances unifying the network, as well as about its peculiarities in their mixture and mutual influence. It is impossible to clarify all issues in a limited set of papers on all aspects of Russian telecommunications, so we have concentrated our attention on the public network as a fundamental part of the Russian telecommunications system.

Switching Equipment Adaptation for Russian Public Telephone Network

Boris S. Goldstein

IEEE Journal on Selected Areas in Communications, vol. 12, no. 7, 1994

This paper describes the adaptation and certification process for switching equipment to be used in the Russian public switched telephone network (PSTN). The first part of the paper illustrates the basic certification procedure and its essential steps. Each step, whether it is described in a natural language or formally in a specification language SDL, is an integral part of the certification process. The described approach improves standardization in the way that specialists at different manufacturers as well as Russian telecommunications engineers use the same methods, the same specification language, and the same test environments. Even the documents for different switching equipment have standardized features. In the second part of this paper, the specification methodology based on formal methods has been shown to work in the adaptation and certification process. It does reduce the number of software errors in the resulting version of adopted switching equipment, and it does improve quality and productivity significantly.

Distinctive Сharacteristics of Call Handling Procedures and Signaling Logic in a Russian Public Telephone Network

Goldstein B., Sloutsky L.

IEEE Journal on Selected Areas of Communications, vol. 12, no. 7, 1994

This article describes main peculiarities of former Soviet Union public switched telephone network (PSTN), signalling systems, call hadling procedures, charging principles, etc. General information about PSTN is also included. The primary goal of the paper is to show some specific PSTN features and give the classification of the existing interfaces rather than to describe existing exchanges in detail.

Teletraffic Models in Advanced Switching Systems Software Engineering

B.S. Goldstein

13th International Teletraffic Congress, Copenhagen, 1991
Discussion circles

The report introduces the teletraffic models for the 5-layers methodology for telecommunication software engineering (R, A, S, P, C). The methodology is oriented on the CCITT language SDL-88.The class of telecommunication software teletraffic model corresponding to software development phases (layers A and S) is discussed: mixed preemptive and non-preemptive priority model with the applications to the analysis and optimization of real time switching software systems. Two modifications of such complex priority system are analyzed. Optimization algorithm for telephone program priority fixing is introduced.
