Chapter 3: Basic Network Technologies
Overview
The purpose of this chapter is to describe the various and popular network transport technologies (transmission media) and network configurations that are available today. We will also address the wireline carriers local loop.
This chapter will further provide the reader with more detailed information about basic engineering concepts. These concepts will assist you with understanding how common network engineering concepts can be applied across different sectors of the telecommunications business. What the following chapter will illustrate is how closely related these networks are and how they are capable of supporting each other.
One of the goals of the network provider (voice or data) is to reduce cost through the allocation of network resources. In other words, the provider wants to operate a network that has been engineered to function economically and that meets the needs of the customer.
The fundamental rules governing traffic engineering are as follows:
- Reduce the number of links (trunks) that are needed to connect all users of the network.
- Reduce the length of the links (lines and trunks) that is needed to connect users to the network.
- Maximize the usage of network facility resources in a given period of time by increasing the number of different connections (trunks) to enable users to communicate with each other or with other resources.
Understanding how a network is designed will enable the reader to understand the reasoning behind a network s design. For example, two wireless service providers provide service to two different markets. The markets, however, have exactly...
