Unit 1 Exercise 1 Local Exchange
9/28/15

The Local Exchange acts as the convergence point for the information sent to the consumers and the point at which services from the global telecommunication are distributed to the consumers. The central office at the local exchange contains the switching equipment to direct your telephone, data, video, etc. to where it needs to go. To understand that you must understand how to interface with the local exchange meaning you must know the different networks that compromise it.
The first network is the access network which is the network that connects the individual user or business with the telecommunications system. It’s a critical part of the network because it’s the part of the network that reaches the end user and “connects them”. This is made up of a series of fiber-optic and copper cabling and passive and active equipment that connects you to the local exchange.
The second network is the metro network, sometimes called the MAN it is where the information is collected from the local exchange of the service provider as well as other service provider and then sent to the regional and long-hauled network. This is usually the last point before the information is sent to the core network.
The purpose of a Network is to share data. To make this possible, you have to be able to connect to other computers. Companies that succeeded at doing this have a great profit with exponential growth possibilities and revenue. For example, Cisco has made billions by allowing different groups of network to share data across what we call the internet.
There is a physical connection running between two computers that wants to connect. This is made possible because phone lines that run from houses to switches to other houses that phone companies let dial each other, or another way would be network
