QUESTION 3

International standard ISO/IEC 11801 specifies general-purpose telecommunication cabling systems (structured cabling) that are suitable for a wide range of applications (analog and ISDN telephony, various data communication standards, building control systems, factory automation). It covers both balanced copper cabling and optical fibre cabling. The standard was designed for use within commercial premises that may consist of either a single building or of multiple buildings on a campus. It was optimized for premises that span up to 3 km, up to 1 km² office space, with between 50 and 50,000 persons, but can also be applied for installations outside this range. A corresponding standard for small-office/home-office (SOHO) environments is ISO/IEC 15018, which also covers 1.2 GHz links for cable and satellite TV applications. The standard defines several classes of twisted-pair copper interconnects, which differ in the maximum frequency for which a certain channel performance is required.

a) Name and Describe briefly the different classes?

b) The Same standard defines several classes of optical fiber interconnect. What are they?

QUESTION 4

SS7 or C7 signalling is the core signaling/control protocol used within fixed and mobile networks. The SS7 network is both a high speed and high availability network providing the backbone of all telephony networks worldwide.

a) Give a brief overview of the SS7 & C7 Standards

b) Discuss about the SS7 Circuit Based Services.

c) Discuss SS7 integration into intelligent networks and mobile-based services and using diagrams show how these services interact?

QUESTION 5

In telecommunications, 4G is the fourth generation of cellular wireless standards. It is a successor of the 3G and 2G families of standards. In 2009, the ITU-R organization specified the IMT-Advanced (International Mobile Telecommunications Advanced) requirements for 4G standards, setting peak speed requirements for 4G service at 100 Mbit/s for high mobility communication (such as from trains and cars) and 1 Gbit/s for low mobility communication (such as pedestrians and stationary users). The world's first publicly available LTE service was opened in the two Scandinavian capitals Stockholm (Ericsson and Nokia Siemens Networks systems) and Copenhagen (a Huawei system) on 14 December 2009.One of the key technologies for 4G and beyond is called Open Wireless Architecture (OWA), supporting multiple wireless air interfaces in an open architecture platform. What are the core requirements that ITU define for a cellular wireless network to fulfill the requirements of a 4G standard?

QUESTION 6

Give a brief on your understanding about the Mauritian Regulatory Framework.

QUESTION 7

Discuss briefly about the National Telecommunications policy that ICTA as a regulating body had put in place in July 2003.

QUESTION 8

The Electronic Transaction Act (ETA) 2000 was enforced and put in place because of the growing requirements for protecting organisational information assets and protect privacy mainly. This legislation came into being to address issues mentioned and contributes towards implementation of an information-secure society. The ETA also sets the necessary framework for some key elements for Mauritius to be a bit more secured. Explain and define the two core areas covered by the ETA?
