Assignment Task This assignment has two parts. Part A consists of a mixture of short and essay-type questions and Part-B requires you to write a short business report based on a casestudy. You are required to complete both parts. Part A Question 1 Critically discuss the type of impairments that exist on a telecommunication transmission channel and its impact on data rate and bit rate capacity of the channel? (15%) Question 2 Critically compare the four different switching techniques in telecommunication networks, namely circuit-switching, message-switching, packet-switching and ATM switching.

(20%) Part B Consider an imaginary Internet Service Provider located in your country that caters to customers such as a call center, IT corporations, hospitals, financial institutions etc. The ISP is consulting with a telecommunication consultancy to optimize the use of the existing infrastructure for maximizing their returns as well as to plan the deployment of newer infrastructure and technologies to cater to the growing demands of their customers. You are expected to produce a technical report addressing the following questions with regards to the given case study. 1. There is an emerging demand from the customers to have converged voice/video/data networks and to securely access the internet services offered by the ISP. You are expected to offer a suitable solution to meet this demand. Implementing Voice and Video Over IP offer a great deal of advantages over traditional telephony services. But they still have their own set of limitations and challenges. Critically discuss the communication architecture and protocol (Session Initiation protocol and others) that enables delivery of voice and video over IP network. Particularly, comment on the limitations of such protocol and the impact it has on voice and video quality. Use appropriate illustrations and references to support your discussion. (25%)2. It is understood that security concerns arise as a consequence of offering voice, video and data over IP network. Critically review the various security issues that may arise in this scenario and describe the protocols and mechanisms that may help mitigate the above concerns.
