Abstract:

In this thesis I counter the received scholarly view that restrictive government policies delayed the uptake of telephony in Britain before its nationalisation in 1912. Rather, I demonstrate how telephone usage shaped British telephone growth and development between 1877, when telephones were first successfully demonstrated in Britain, and 1893, when the decision to nationalise the trunk lines had been taken and competition between private companies ended. My use-focused approach differs from previous supply-centred narratives in four important respects: instead of considering only exchange telephony, I also focus on private, point-to-point telephony, and innovative uses of telephone instruments devised by users. Secondly, whilst most focus on London, I also examine events in the provinces. Thus I show how developments in telephony around the country had national effects. Thirdly, I question how well telephony met the needs of individuals and groups when compared with efficient alternative communication methods such as telegraphy and the letter post. Finally, I also examine the actions and opinions of non-users of telephony, who often preferred to use more traditional methods of communication. Thus, by studying material from the BT Archives, and digitised Victorian periodical sources, I demonstrate how telephone users and non-users contributed to three Victorian discussions: the first concerned who ought to supply telephony, for example, companies or the state, and whether competition or monopoly was preferable. The second was who should be able to use telephony, whether it was a luxury or a necessity, and for whom; the third concerned the uses to which the embryonic technology ought to be put. The answers to these three questions of ownership, entitlement and purpose shaped the variety of telephone systems which emerged around the country by the end of the period covered by this thesis. I argue that users and non-users influenced the development of British telephony by deciding to adopt or reject the telephone, by the uses to which they put telephone instruments, or by deciding to impede the growth of telephone systems. Overall, I show that by 1893 it was the agency of users and non-users which led to the British government's decision to nationalise the trunk lines, and to the end of private competition in exchange telephony.

Abstract:

Thesis (Masters Diploma (Electrical Engineering) -- Cape Technikon, Cape Town,1991
Communication in all its various forms, has always played an important role in both the business and social environments. The conventional telephone, taken more often than not for granted, is responsible for keeping over five million people in South Africa alone, in daily contact. For the deaf and mute society, of which their are approximately 300 000 in South Africa, the telephone, on its own, has remained a useless gadget. Without the aid of a personal computer or terminal and a modem, communication for the deaf via the PSTN (Public Switched Telephone Network) has been impossible. Use of computers may be one way of overcoming this obvious problem, but expense now becomes the more important issue. To analyse the situation, two issues had to be taken into consideration. The first is, what makes the above solution so expensive, and the secondly, is thi!t expensive equipment necessary to complete the relatively simple task of interactive communication. The technology built into todays personal computers is continuously changing and in order to keep up with these changes, regular upgrades to the computer are necessary if one intends being able to recover ones investment at a later stage. The cost of a modem, with its sophisticated error-eorrection routines and auto-dial software, can also increase the initial outlay considerably. Bearing these costs in mind, it must now be investigated how one can achieve the objective of communicating with only the bear essential. By replacing the PC's monitor with a Liquid Crystal Display, the powerful processor with a relatively simple one, eliminating the disk storage entirely, reducing the on-board ROM!RAM memory, and finally, substituting a single-chip low speed modem for the free standing modem, the cost can be drastically reduced. By combining all these components together and developing a program to control them, the result is the 'Voiceless Telephone".

Full text

Abstract:

Impulse noise is an ever increasing impediment to successful digital data transmission in the telephone local cable plant. Two major factors have caused this to happen. Firstly, remedies have been found for nearly all the other causes of signal degradation, such as crosstalk and intersymbol interference, leaving impulse noise outstanding. Secondly, the user's demand for higher and higher data rates and the proliferation of repeaterless operation at extended loop ranges, have made the effects of impulse noise more prominent. This thesis covers the subject of impulse noise in the local plant. It begins with experimental data obtained from field studies of the local loop segments of digital transmission systems. The theoretical aspects of impulse noise are next addressed, including the various methodologies for modeling it. Burst errors in the recovered data stream, and their relationship with impulse noise, their principal cause, are described. The methodologies for modeling burst errors are then discussed. Finally, the techniques for minimizing the harmful effects of impulse noise are examined. Included in this is a novel scheme, referred to as "Pulse Sharpening", now being introduced.

Full text

Abstract:

This thesis explored one form of communication apprehension, namely telephone apprehension, defined as "anxiety or fear associated with the anticipated or actual use of the telephone". Using a self-report questionnaire, data from UK and Australian student and non-student samples indicated significant sex (male>female), non-significant age, but significant age by sex interactions (older men>older women, younger nsd). Culture and sample differences were significant (UK>Australian>USA; students>non-students). Correlations between apprehension and use were small. Factor analyses suggested that telephone apprehension comprised three independent factors. "Problematic Communication" focuses upon apprehension, whilst "Approach-Avoidance" involves overall like-dislike and use-avoidance. "Confidence" concerns self-perceived competence. This analysis implied that there was no necessary relation between telephone apprehension and use-avoidance. A validity study concluded that a revised self-report questionnaire incorporating distinctions between using, communicating, speaking and listening by telephone was an appropriately specified, valid and reliable measure of telephone apprehension. An investigation of the correlations of telephone apprehension with generalised anxiety, communication apprehension, social desirability and self-esteem showed that these were non-significant, and accounted for only 6.4% of the overall variance in telephone apprehension. It was concluded that differences in telephone apprehension do not result merely from differences in other, more generalised personality or communication variables. A critical review of the concept of telephone apprehension, and of communication apprehension in general, lead to the redefinition of telephone apprehension within an expectancy-value framework, as the summed product of the evaluative components of beliefs about the negative affective outcomes of telephone use, and their associated outcome expectancies. In addition to apprehension, other variables should be incorporated in predictive models of telephone use, such as non-affective outcome expectancies and evaluations, and self-efficacy expectancies. A combined expectancy-value and selfefficacy model was proposed which incorporated telephone apprehension as one of the predictor variables.

Thesis (MSc)--University of Stellenbosch, 2005.
ENGLISH ABSTRACT: Cellular network operators globally loose between 3% and 5% of their annual revenue to telecommunications fraud. Hence it is of great importance that fraud management systems are implemented to detect, alarm, and shut down fraud within minutes, minimising revenue loss. Modern proprietary fraud management systems employ (i) classification methods, most often artificial neural networks learning from classified call data records to classify new call data records as fraudulent or legitimate, (ii) statistical methods building subscriber behaviour profiles based on the subscriber’s usage in the cellular network and detecting sudden changes in behaviour, and (iii) rules and threshold values defined by fraud analysts, utilising their knowledge of valid fraud cases and the false alarm rate as guidance. The purpose of this thesis is to establish a context for and evaluate the performance of well-known data mining techniques that may be incorporated in the fraud detection process. Firstly, a theoretical background of various well-known data mining techniques is provided and a number of seminal articles on fraud detection, which influenced this thesis, are summarised. The cellular telecommunications industry is introduced, including a brief discussion of the types of fraud experienced by South African cellular network operators. Secondly, the data collection process and the characteristics of the collected data are discussed. Different data mining techniques are applied to the collected data, demonstrating how user behaviour profiles may be built and how fraud may be predicted. An appraisal of the performances and appropriateness of the different data mining techniques is given in the context of the fraud detection process. Finally, an indication of further work is provided in the conclusion to this thesis, in the form of a number of recommendations for possible adaptations of the fraud detection methods, and improvements thereof. A combination of data mining techniques that may be used to build a comprehensive fraud detection model is also suggested.
AFRIKAANSE OPSOMMING: Sellulêre netwerk operateurs verloor wêreldwyd tussen 3% en 5% van hul jaarlikse inkomste as gevolg van telekommunikasie bedrog. Dit is dus van die uiterse belang dat bedrog bestuurstelsels geïmplimenteer word om bedrog op te spoor, alarms te genereer, en bedrog binne minute te staak om verlies aan inkomste tot ’n minimum te beperk. Moderne gepatenteerde bedrog bestuurstelsels maak gebruik van (i) klassifikasie metodes, mees dikwels kunsmatige neurale netwerke wat leer vanaf geklassifiseerde oproep rekords en gebruik word om nuwe oproep rekords as bedrog-draend of nie bedrog-draend te klassifiseer, (ii) statistiese metodes wat gedragsprofiele van ’n intekenaar bou, gebaseer op die intekenaar se gedrag in die sellulêre netwerk, en skielike verandering in gedrag opspoor, en (iii) reëls en drempelwaardes wat deur bedrog analiste daar gestel word, deur gebruik te maak van hulle ondervinding met geldige gevalle van bedrog en die koers waarteen vals alarms gegenereer word. Die doel van hierdie tesis is om ’n konteks te bepaal vir en die werksverrigting te evalueer van bekende data ontginningstegnieke wat in bedrog opsporingstelsels gebruik kan word. Eerstens word ’n teoretiese agtergrond vir ’n aantal bekende data ontginningstegnieke voorsien en ’n aantal gedagteryke artikels wat oor bedrog opsporing handel en wat hierdie tesis beïnvloed het, opgesom. Die sellulêre telekommunikasie industrie word bekend gestel, insluitend ’n kort bespreking oor die tipes bedrog wat deur Suid-Afrikaanse sellulˆere telekommunikasie netwerk operateurs ondervind word. Tweedens word die data versamelingsproses en die eienskappe van die versamelde data bespreek. Verskillende data ontginningstegnieke word vervolgens toegepas op die versamelde data om te demonstreer hoe gedragsprofiele van gebruikers gebou kan word en hoe bedrog voorspel kan word. Die werksverrigting en gepastheid van die verskillende data ontginningstegnieke word bespreek in die konteks van die bedrog opsporingsproses. Laastens word ’n aanduiding van verdere werk in die gevolgtrekking tot hierdie tesis verskaf, en wel in die vorm van ’n aantal aanbevelings oor moontlike aanpassings en verbeterings van die bedrog opsporingsmetodes wat beskou en toegepas is. ’n Omvattende bedrog opsporingsmodel wat gebruik maak van ’n kombinasie van data ontginningstegnieke word ook voorgestel.

South, Colin R. "Signal processing in a loudspeaking telephone." Thesis, Aston University, 1985. http://publications.aston.ac.uk/8053/.

Full text

Abstract:

One of the major problems associated with communication via a loudspeaking telephone (LST) is that, using analogue processing, duplex transmission is limited to low-loss lines and produces a low acoustic output. An architectural for an instrument has been developed and tested, which uses digital signal processing to provide duplex transmission between a LST and a telopnone handset over most of the B.T. network. Digital adaptive-filters are used in the duplex LST to cancel coupling between the loudspeaker and microphone, and across the transmit to receive paths of the 2-to-4-wire converter. Normal movement of a person in the acoustic path causes a loss of stability by increasing the level of coupling from the loudspeaker to the microphone, since there is a lag associated the adaptive filters learning about a non-stationary path, Control of the loop stability and the level of sidetone heard by the hadset user is by a microprocessoe, which continually monitors the system and regulates the gain. The result is a system which offers the best compromise available based on a set of measured parameters. A theory has been developed which gives the loop stability requirements based on the error between the parameters of the filter and those of the unknown path. The programme to develope a low-cost adaptive filter in LST produced a low-cost adaptive filter in LST produced a unique architecture which has a number of features not available in any similar system. These include automatic compensation for the rate of adaptation over a 36 dB range of output level, , 4 rates of adaptation (with a maximum of 465 dB/s), plus the ability to cascade up to 4 filters without loss o performance. A complex story has been developed to determine the adptation which can be achieved using finite-precision arithmatic. This enabled the development of an architecture which distributed the normalisation required to achieve optimum rate of adaptation over the useful input range. Comparison of theory and measurement for the adaptive filter show very close agreement. A single experimental LST was built and tested on connections to hanset telephones over the BT network. The LST demonstrated that duplex transmission was feasible using signal processing and produced a more comfortable means of communication beween people than methods emplying deep voice-switching to regulate the local-loop gain. Although, with the current level of processing power, it is not a panacea and attention must be directed toward the physical acoustic isolation between loudspeaker and microphone.

Abstract:

Telefonen har under de senaste årtiondena blivit ett viktigt redskap i hälso- och sjukvårdens arbete med människor som söker hjälp och råd för medicinska problem. Telefonlinjer till Sveriges vårdcentraler inrättades allmänt på 1970-talet. En betydande del av sjuksköterskornas arbete på vårdcentral består av telefonrådgivning. Den vårdsökande prioriteras och hänvisas till rätt vårdnivå utifrån den bedömning som görs vid dessa samtal. Syftet med studien är att få kunskap om vad sjuksköterskorna upplever när den vårdsökande inte kan beredas tid trots ett medicinskt behov, då läkartiderna inte räcker till på grund av brist på allmänläkare. Tio sjuksköterskor som arbetar med telefonrådgivning på vårdcentral intervjuades. Studien utfördes med en kvalitativ metod med fenomenologisk ansats. I resultatet framkommer att informanterna har flera olika känslomässiga upplevelser. Informanterna upplever att de inte alltid kan uppfylla det vårdgarantin lovar, men att problemet är organisationsrelaterat och ligger utanför deras egen kontroll. Telefonarbetet kan kännas betungande och tanken på hur det går för den vårdsökande finns ibland kvar efter arbetsdagens slut. Erfarenhet och kunskap anses viktigt för att bättre kunna hantera situationen och göra rätt bedömning. Det kollegiala stödet framhålls som betydelsefullt. Det anses viktigt att noggrant dokumentera givna råd och vilka åtgärder som planerats.

During the past decades the telephone has become an important tool in the healthcare system when people seek help and advice for medical problems. Telephone lines to all healthcare centres in Sweden were established in the 1970´s. A large part of nurses´ work at a healthcare centre consists of giving telephone advice. The callers´ medical needs are assessed and the callers are referred to the proper level of care. The aim of this study is to find out what nurses experience when the caller cannot be given an appointment, despite a medical need for one, because there are insufficient medical appointments available due to a shortage of general practitioners. Ten nurses working with telephone advice at healthcare centre were interviewed. The study was done with a qualitative method using a phenomenological approach. Results indicate that the informants have several different emotional experiences. The informants experience that they cannot always live up to the care guarantee, but that the problem is organizational and beyond their control. Sometimes telephone work feels heavy, and thoughts of how things go for the caller can continue when the work-day is finished. Experience and knowledge are considered important in order to be able to handle the situation better and to make a correct assessment. Support from colleagues is pointed out as meaningful. It is considered important to carefully document the advice given during the telephone call and which measures are planned.

Abstract:

In the last fifteen years Accident and Emergency (A & E) departments have become the default environment for service users seeking help during a mental health crisis. Simultaneously, the Police have reported concerns about the expectations placed on their officers in dealing with the rising numbers of people experiencing a mental health crisis. In 2014 the Home Office launched The Crisis Care Concordat requiring statutory and non-statutory organisations to make a commitment to work together to ensure a seamless pathway for anyone who experiences a mental health crisis, regardless of their first contact with services. To facilitate this many new initiatives were developed, Street Triage being one. This allows the police immediate access to a mental health professional when they find themselves attending an incident or event that has a mental health component. Whilst there is an emerging body of research focusing on the organisational and financial benefits to such services, there is limited research regarding the experience of the service user utilising such services. The aim of this study was to explore and understand the experiences of service users, who when experiencing a mental health crisis were treated by the Street Triage Service. Qualitative research, using a narrative approach was used to address this aim. Data were collected through one to one narrative interviews with three service users. Interview transcripts were initially analysed as individual stories, and then as a collective, recognising the nuances of each narrative and also exploring the cross commonalities. While each narrative had its own unique themes some, shared commonalities were also identified. These included; (1) Learning from their own experiences, (2) Perceiving and interacting with blue light services and (3) Interacting with the Street Triage team. Individuals who have experienced a mental health crisis and used the Street Triage service offer a wealth of knowledge that not only contributes to the emerging body of research in this area, but also enables the development of such services in better meeting the needs of those who may require such services in the future.

Abstract:

The Telephone Voice Alert is divided into six parts: the ring detector, controller, voice memory, synthesizer, speaker, and power supply subsystems. These all interact together to produce a voice signal whenever a ring signal is detected. By beginning from the system function and analyzing the components as we break the system into subsystems, we find that the trade-off between system cost and system "effectiveness" minimizes to prove Configuration A (digital voice reproduction) a more effective means. Further testing and development is necessary, however, as the design must be "fine-tuned" in order to insure proper function.

Abstract:

This thesis is a proposal for a new approach to the investigation of the language of telephone conversations. It strives to integrate the framework of analysis advocated by conversation analysts (originally the first to examine these conversations) and that of pragmaticists, in an attempt to provide description and explanation of telephone behaviour. It is based on the examination of telephone talk in Ecuadorian Spanish and British English. Such an approach requires the examination of these conversations at four levels - the level of their underlying structure which is analyzed in terms of skeletons, paths and moves, the linguistic realization of moves in relation to features of context, the politeness orientations behind moves and their linguistic realizations, and finally, the socio-cultural motivations behind linguistic choices and politeness orientations. In addition, this thesis constitutes a study in cross-cultural communication in that it attempts to determine basic similarities and differences in the organization of telephone conversations in two languages and cultures, which can provide insights into broader differences in the linguistic and politeness systems of those two languages.

Abstract:

The telenursing service deals with offering the public guidance as what to do with their health and illness concern. More specifically this service includes triage, support, advice, education, referral, information and coordination. To conduct telephone advice is a complicated task to perform and put specific demands of the nurse’s communication skills. The purpose of this study was to critically review the impact of telephone counseling focused on context of implementation, perspective, design and clinical relevance by a sample of studies within the field. The critical review focused on inconsistencies in the material. Strengths and weaknesses of the studies were explored, with emphasis on detecting areas of skill gaps. Twelve of thirteen studies were made in the context of telenursing. The thirteenth was conducted in the context of the emergency call. The most prominent approach was the study of callers´. Two of the articles were made with an inductive design, five with a deductive and the remaining six articles with a mixed design. The clinical relevance is attached to the callers´ perspective. The most salient dimension of the analyzed studies were studies of callers´ satisfaction with telephone advice, compliance to advice given and experiences of approaching a telenurse. The results reveal that when given advice are understood, satisfaction with the advice is obtained as well as good compliance and the caller feel looked after. However, the callers´ experience to ventilate their concerns, being listened to, while having "control" over the call is less explored. Moreover, the callers´ experience of being subject to advice by telephone seems to be further explored.

Abstract:

This degree project was made in collaboration with Nordicstation. The project task was to develop a testing application for a self-developed telephone survey service, which uses third party software. This third party software showed to be unreliable at higher loads. The purpose of the application is to analyse the speech quality of clients connected to the service. This report gives an introduction to the speech quality algorithms Perceptual Evaluation of Speech Quality (PESQ) and Single Sided Speech Quality Measure (3SQM). It also gives descriptions of the methods used to develop the application. The final chapters in this report are about the testing of the telephone service. The primary result of the testing was that the telephone service is unable to acceptably handle 80+ clients and recommendations to Nordicstation is to set a maximum of parallel connected clients to 80 or find an alternative to the third party software currently in use.
Detta examensarbete har gjorts i samarbete med Nordicstation. Projektets uppgift var att utveckla ett test program för at testa en egenutvecklad telefonundersökning-tjänst, baserad på tredjeparts mjukvara. Denna tredjeparts mjukvara visade sig vara opålitlig vid högre belastning. Syftet med programmet är att analysera samtals kvalitéten på de klienter som är anslutna till tjänsten. Denna rapport ger en introduktion till ljudkvalitetsalgoritmer så som Perceptual Evaluation of Speech Quality (PESQ) och Single Sided Speech Quality Measure (3SQM). Rapporten går även igenom de metoder som använts för att utvecklat programmet. De sista kapitlen i denna rapport är om själva testningen av telefonitjänsten. Det primära resultatet av testningen var att telefontjänsten inte kan hantera 80+ klienter acceptabelt och rekommendationer till Nordicstation är att sätta ett tak på maximalt parallellt anslutna klienter till 80 eller hitta ett alternativ till den tredjeparts mjukvara som nu används.

Abstract:

This exploratory study examined outcomes of single telephone counselling calls, with a self-selected sample of 38 clients from a family counselling agency. The sample was interviewed by telephone at two days and six weeks after the call to assess crisis counselling outcomes in affect, identification of the problem and action taken, and client equilibrium. Repeated measures of the 'perceptual concordance' of counsellor and client were taken over a period of six weeks, assessing levels of concordance between client and counsellor about perceptions of counselling, and client equilibrium. The sufficiency of a single counselling session was also assessed. 'Perceptual concordance' was suggested by reduced client stress, high levels of agreement between client and counsellor in the identification of the problem and agreed action, and satisfaction with the counselling. Positive indicators of restored client equilibrium included a maintenance of lower stress levels, changes in behaviour, improvement in perceptions of the seriousness of the problem, satisfaction with life and with the counselling. Further research of equilibrium as a concept, and an indicator of crisis resolution is warranted. The sufficiency of a single session of counselling was supported by 56% of clients. The variety of services used by clients as an outcome of the counselling suggests that it could be beneficial for telephone counselling agencies to offer a follow-up call. Verifying the agreed action and assessing equilibrium could be useful indicators of effective telephone counselling.

Abstract:

Telephones are an integral part of everyday life in today's society. It is well known that hearing impaired people have difficulty understanding speech on the telephone. The ability to use the telephone is commonly reported as one of the many benefits of cochlear implantation. Assessment for a cochlear implant (CI) includes a variety of aspects related to communication and hearing ability. Included in the case history, mention is made whether the person can use the telephone. The purpose of the present study was firstly to identify if the inability to use the telephone could be used a predictor for suitability for a cochlear implant. It was also purposed to determine if telephone ability could be assessed by self-reported measures. The participants were 13 severe to profoundly hearing impaired people who had previously undergone candidacy assessment for a cochlear implant. Each participant was evaluated on their use and understanding of speech on the telephone. Participants were separated into two groups: those who were candidates for a cochlear implant and those who were not. Speech perception testing was evaluated using a recording of CUNY sentences on the telephone. Results indicated that cochlear implant candidates correctly perceived a significantly lower number of words on the telephone than non-candidates. Use of the telephone was evaluated using a 51-item questionnaire. Results indicated that there was no significant difference in self-reported use of the telephone between cochlear implant candidates and non-candidates. The differences in speech perception understanding on the telephone were most likely due to the overall better hearing levels of the non-candidates. The clinical implications of the present study are considered.
