The paper reviews chapter one of "Telecommunications Essentials" and looks at how Goleniewski discusses the fundamentals of telecommunications technology. The paper outlines how she discusses how data is transmitted, the differences between analog and digital signals and multiplexing, and finally, the topic of regulatory agencies and how these agencies have had a definitive impact on the telecommunications industry. This paper asserts that Goleniewski provides a good guide to the basics of telecommunications technology, and she offers a substantial amount of information, but she leaves the reader to draw conclusions about the implications of this information.
From the Paper:"Chapter one begins with a discussion of the requirements for successful communication. Goleniewski makes it clear that understandability is a prerequisite for communication, as is the capability to detect errors (Goleniewski). Next, she goes on to describe various types of communications pathways. She discusses circuits, which she defines as "the physical path that runs between two or more points" (Goleniewski). The ends of the circuit are called ports. Channels are conversation paths, and refer to the "frequency band, time slot, or wavelength allocated to a single conversation" (Goleniewski). Lines and trunks are similar to channels, but lines are connections aimed at supporting one user's needs, while trunks are connections that service a group of individuals (Goleniewski). However, most of today's communication pathways are not physical but are virtual. "Unlike a physical circuit, which terminates on specific physical ports, a virtual circuit is a series of logical connections between sending and receiving devices," and which simulates an actual physical connection (Goleniewski). Virtual circuits can be permanently available (PVCs) or set up on demand (SVCs) (Goleniewski). She explains that networks can be connected in three main ways: switched network connections, which use a series of network switches to establish a connection, leased-line network connections, which mean that the same devices are always connected, and dedicated network connections that work in a way similar to leased-line network connections (Goleniewski)."
