...Exercise One Nt1310 Week 1 In: Computers and Technology Exercise One Nt1310 Week 1 NT1310:Week 1 Telecommunications By: Kenneth Martin You are an IT Network Specialist and are required to develop the design of the company’s telephone system for its new building which will begin construction in a few months. In order to get a background which will help when developing the new system, your supervisor asked you to research the current Plain Old Telephone Service (POTS) currently used by the company. You must research the system components and report back to your supervisor , the Telecommunications Manager, within a week. 1. Describe a local land line phone system based on the following Landline Telephone Components: a. Local Loop a local loop is the wired connection from a telephone company's central office in a locality to its customers' telephones at homes and businesses. This connection is usually on a pair of copper wires called twisted pair. The system was originally designed for voice transmission only using analog transmission technology on a single voice channel. Today, your computer's modem makes the conversion between analog signals and digital signals. With Integrated Services Digital Network (ISDN) or Digital Subscriber Line (DSL), the local loop can carry digital signals directly and at a much higher bandwidth than they do for voice only. b. Central Office In telephone communication in the United States, a central office (CO) is an office in a locality...

...NT1310 Unit 7 Assignment 1: Crosstalk a disturbance caused by the electric or magnetic fields of one telecommunication signal affecting a signal in an adjacent circuit Waveguides an electromagnetic feed line used in microwave communications, broadcasting, and radar installations FTTH is the installation and use of optical fiber from a central point directly to individual buildings such as residences, apartment buildings and businesses Simplex a communications mode in which only one signal is transmitted, and it always goes in the same direction Half-Duplex data can be transmitted in both directions on a signal carrier, but not at the same time. Full-Duplex data can be transmitted in both directions on a signal carrier, at the same time. 1. Photodiode a semiconductor diode that, when exposed to light, generates a potential difference or changes its electrical resistance Amplitude Modulation the transmission of data by varying the amplitude of the individual pulses in a regularly timed sequence of electrical or electromagnetic pulses. Analog Transmission a base carrier's alternating current frequency is modified in some way, such as by amplifying the strength of the signal or varying the frequency, in order to add information to the signal Digital Transmission the physical transfer of data over a point-to-point or point-to-multipoint communication channel. Sample Rate the number of samples of a sound that are taken per second to represent the event digitally...

But Best Practice dictates to move some of theese Flexible Single Master of Operation (FSMO) roles to seperate servers. If you only have one domain controller (not recommended), there is nothing to do since all roles must be on this server, but if you have multiple servers you should move some of theese roles on to more servers. It is also important to be aware of what servers are Global Catalog servers, especially if you have more than one domain and even if only one domain, they will be prefered by applications like Exchange server. It is recommended to place the forest roles on one Domain Controller (DC) and the domain roles on another server. If not all Domain Controllers are Global Catalog servers, it is also important to place the infrastructure master on a server that is NOT a Global Catalog server. Recommended Best Practice setup of FSMO roles. Domain Controller #1 Place the two forest roles on this server. * Schema Master...
