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
a. Local Loop
A local loop is the wired connection from a telephone company’s central office in a locality ...view middle of the document...
f. Fixed Line
Fixed Line is a line that is not a mobile phone line, can be hard-wired or cordless. It usually derive electrical power form the utility mains electricity, unlike mobile wireless or portable wireless, which tend to be battery-powered.
2. Define and describe the following Telecommunications Network Components:
a. Cellular Telephones:
Wireless service providers offer voice plans, also known as talk plans, in conjunction with text services. Voice plans, with or without text, offer varying allotments of time for which can be used during any given month.
Data plan is a stand-alone service, and it’s available in varying allotments, measured by megabytes and gigabytes. In other words, as an estimate, it can access approximately 400 websites per month on the data plan. The minimum amount of data provided by wireless service providers varies, but all four offer data plans that include an unlimited amount of data.
b. Telephone Network Topology:
i. Demarcation Point
It’s the physical point at which the public network of a telecommunication company ends and the private network of a customer begins, this is usually where the cable physically enters a building.
It’s used to combine, split, switch, boost, or direct packets of information along a computer or telecommunications network. It interconnects devices so that data can be shared. The layout of topology of these connected devices describes the network’s design or structure.
iii. Access Networks
An access network is the part of a telecommunications network which connects subscribers to their service provider. It is contrasted with the core network, which connects local providers to each other.
iv. Regional/Metro Networks
The need for metropolitan and region-wide wireless Internet access is expected to rise sharply. In order to meet the needs of the emerging market the IEEE has begun forming new working groups to define the wireless standards of the future. The technical aspects of the 802.16, 802.20 and 802.22 was created in order to define new wireless standards which can provide the necessary technology to support fully wireless ISP’s as well as compete with current and next generation cellular technologies.
c. Cable TV
i. Broadcast TV
It’s a program that is transmitted over airwaves for public reception by anyone with a receiver tuned to the right signal channel.
ii. Community Antenna
A single source of television signals transmitted to multiple receivers. Used in buildings that have television cables. Can be integrated in the building’s communications system.
