Telephone networks use circuit switching. The telephone network had its beginnings in the late 1800s. The entire network, which is referred to as the plain old telephone system (POTS), was originally an analog system using analog signals to transmit voice.
You will find certain words or phrases criticized here listed in dictionaries. Note carefully labels like dial. (dialectical), nonstandard, and obsolete before
assuming that the dictionary is endorsing them. The primary job of a dictionary is to track how people actually use language. Dictionaries differ among
themselves on how much guidance to usage they provide; but the goal of a usage guide like this is substantially different: to protect you against patterns
which are regarded by substantial numbers of well-educated people as nonstandard....

A circuit-switched network consists of a set of switches connected by physical links. A connection between two stations is a dedicated path made of one or more links. However, each connection uses only one dedicated channel on each link. Each link is normally divided into n channels by using FDM or TDM.
In this work, we provide an empirical analysis of differences in word use between genders in telephone conversations, which complements the considerable body of work in sociolinguistics concerned with gender linguistic differences. Experiments are performed on a large speech corpus of roughly 12000 conversations. We employ machine learning techniques to automatically categorize the gender of each speaker given only the transcript of his/her speech, achieving 92% accuracy. An analysis of the most characteristic words for each gender is also presented.
We use an EM algorithm to learn user models in a spoken dialog system. Our method requires automatically transcribed (with ASR) dialog corpora, plus a model of transcription errors, but does not otherwise need any manual transcription effort. We tested our method on a voice-controlled telephone directory application, and show that our learned models better replicate the true distribution of user actions than those trained by simpler methods and are very similar to user models estimated from manually transcribed dialogs. ...
Chapter 9 - Using telephoneand cable networks for data transmission. This chapter shows how the issues discussed in the previous chapters can be used in actual networks. In this chapter, we first discuss the telephone network as designed to carry voice. We then show how it can be used to carry data. Second, we discuss the cable network as a television network. We then show how it can also be used to carry data.

Most pipelines are operated twenty-four hours a day from a control station, using telephone, satellite, or microwave communications systems. Computers are widely used to monitor conditions along the line every ten to sixty seconds, sounding an alarm if they detect any abnormality or sudden change in pressure. In the event of an alarm, valves can be closed and nearby pipeline crews dispatched within minutes.

Another important strategy is to make 60-sec-ond telephone assignments. The TOEFL Academ¬ic Speaking Test (TAST), which is a preliminary version of the Speaking Section on the Next Gen¬eration TOEFL, is currently administered by tele¬phone. To prepare our students for this new expe¬rience, some of us are experimenting with phone-in speaking practice by using telephone answering machines to record our students when they call.
