Web-based telephony bridges for the deaf

A Teldem provides text-based telephony services to the deaf. Despite an array of text-based communications mechanisms on the web, the Teldem is the only means of synchronous telecommunication available to a deaf person. We examine a human-assisted relay that provides a bridge between the deaf and the hearing, and then propose several additional bridges. These bridges take advantage of both standard and cutting edge technologies. We present each bridge's impact on the deaf with respect to synchrony, connectivity, independence, and the Digital Divide. It is hoped that by deploying trials for each bridge, we can eventually provide the deaf with equal access.Telkom, Siemens, THRIPDepartment of HE and Training approved lis

DSL-based triple-play services

This research examines the triple play service based on the ADSL technology. The voice over IP will be checked and combined with the internet data by two monitoring programs in order to examine the performance that this service offers and then will be compared with the usual method of internet connection.This research examines the triple play service based on the ADSL technology.

The impact of implementation of VOIP in call centres : A Western Australia perspective

By fostering the finalization of open standards and the convergence of voice, video and data, the internet protocol provides an ideal driver for the definition of the infrastructure of new multimedia and advanced communications applications (Adams & Bhalla, 2005). The key advantages of Voice over Internet Protocol (VoiP) for enterprises have been the promise of lower costs, infrastructure consolidation and increased flexibility. Carriers are also positioning VoiP as a cost-saving business solution. It is an application which seemed like a godsend to business and people alike who rely on telephony services (Blood, 2005). The aim of this study was to investigate what factors may influence the adoption of VoiP as a technology as a West Australia context. Specifically the research undertook a case study using an establish call centre in a government agency, City of Melville. The company is a provider of wide range of services including recreation centres, aquatic centres, libraries, creches, pre-school centres, community centres, food inspection services, citizenships, recycling, planning and building services, maintenance, streetscapes, landscaping disability services, immunisation clinics, cultural and educational centres, environmental preservation and management. This study analysed the steps through to adoption of VoiP and IP telephony from the original technology for the Melville City Council call centre. Also, the procedures towards acquisition and installation of the supporting framework that eases the implementation and day to day running are depicted. The main impacts on the company as a result of the implementation in terms of cost reduction and implications, staff satisfaction and benefits, ease of business operations has been reported in this study. Statistics of the business functions and operations based on VoiP solutions were critically analyzed. Results from the research suggested further research needs to be undertaken on factor affecting the adoption of VoiP in a Western Australia context

Network Neutrality: A Research Guide

The conclusion in a research handbook should emphasise the complexity of the problem than trying to claim a one-size-fits-all solution. I have categorised net neutrality into positive and negative (content discrimination) net neutrality indicating the latter as potentially harmful. Blocking content without informing customers appropriately is wrong: if it says ‘Internet service’, it should offer an open Internet (alongside walled gardens if that is expressly advertised as such). The issue of uncontrolled Internet flows versus engineered solutions is central to the question of a ‘free’ versus regulated Internet. A consumer- and citizen-orientated intervention depends on passing regulations to prevent unregulated nontransparent controls exerted over traffic via DPI equipment, whether imposed by ISPs for financial advantage or by governments eager to use this new technology to filter, censor and enforce copyright against their citizens. Unraveling the previous ISP limited liability regime risks removing the efficiency of that approach in permitting the free flow of information for economic and social advantage. These conclusions support a light-touch regulatory regime involving reporting requirements and co-regulation with, as far as is possible, market-based solutions. Solutions may be international as well as local, and international coordination of best practice and knowledge will enable national regulators to keep up with the technology ‘arms race’
