These SLGs, which are believed to be a world first, have been set up so that customers are automatically rebated in the event of a service disruption. This means the customer will be rebated regardless of whether they were aware of the outage.[81]
2.65 In evidence to the Committee the ACA confirmed that it does not monitor broadband or ADSL faults, although it is considering doing so.[82] In its submission Agile suggested that the National Reliability Framework should be extended to ADSL broadband services.[83] Given the growing importance of data services to both consumers and the economy the Committee believes that monitoring of service standards must extend to data services.
2.66 The generic term cable is generally used to refer to a network of hybrid fibre coaxial cable through which pay TV services are provided to households. The networks consist of optical fibre on main routes, supplemented by coaxial cable closer to the customers premises. These networks can also be used to provide Internet access with download speeds of 256-2000 kbps and upload speeds of 128 kbps. Unlike the way ADSL operates with an individual connection for each customer, cable users share access to the same HFC loop, meaning cable speeds can be affected when a large number of users are accessing the network at the same time. There are 215,400 cable broadband services connected in Australia.[84]
2.67 The biggest drawback with cable broadband is the limited extent of access to the existing cable networks:[85]
When I contacted Telstra, they simply said "there is no cable in your area, so you can't be connected to either Foxtel cable TV or the Internet cable network".
We had to pay $2,700 to have a satellite dish installed to receive Foxtel "cable" TV.[86]
2.68 Even where the physical infrastructure exists, access is not always available:
Optus has a cable obtrusively erected on the power poles in front of our units. It is 1.5metres from the wall of the units and a conduit is in place where the cable can be installed. There is a communications room set aside for any equipment Optus may need to install and all units are already wired back to the communications room. Optus will not even talk to us other than to say, "we don't connect to home units".[87]
2.69 The number of broadband services being provided by HFC cable grew by 52.9% between June 2002 and June 2003.[88]
2.70 Integrated Services Digital Network (ISDN) is a reliable, well established technology for transmitting data. It is a digital alternative to an analogue public switched telephone service, which uses copper telephone lines to carry a 64 kbps data service. Telstra is currently marketing an ISDN Home product which uses two ISDN lines to provide a 128 kbps service. This speed is lower than that which is generally accepted as falling into the definition of broadband and the ACCC does not collect figures on ISDN in its Snap Shot of Broadband Deployment. But ISDN does have the advantage that it is significantly faster than dial-up access to the Internet. Higher speeds can be achieved by combining more ISDN lines but these services are generally only affordable by business users.
2.71 ISDN enjoys advantages over other technologies for some users. While cable and ADSL have significant limits on their availability, ISDN is available to 96 per cent of the Australian population. Because it is an older technology it is available to customers served by some pair gain systems which will not support ADSL and, with the use of repeaters, is available up to 20 kilometres from an exchange.[89] ISDN provides a symmetrical service which is more suitable than ADSL for customers who upload significant amounts of data to the Internet. Nevertheless some submitters to the Committee expressed concern that ISDN does not free up a phone line[90] and that it is relatively expensive.[91]
2.72 In its most recent publication on Internet activity the Australian Bureau of Statistics reported that the number of ISDN subscriptions had fallen from 16,000 at the end of March 2003 to 14,000 at the end of September 2003.[92]
2.73 The most widely available method of gaining access to broadband technology is by satellite. Satellite broadband is available throughout Australia. It represents the most suitable technology in areas where population densities are very low. Satellites are radio relay stations in orbit above the Earth that receive, amplify and redirect radiocommunications signals.
2.74 There are three ways of accessing broadband by satellite.
2.75 All of the satellites operated in Australian satellite slots are owned and managed by Optus, although transponders on those satellites are leased by other telecommunications companies. Some satellites operated from overseas can be used to provide services into Australia.
2.76 The principal drawback associated with satellite services is the cost. Satellite access involves higher upfront costs than other technologies and the ongoing cost of satellite access is usually higher than for other forms of broadband. Many submitters put the view to the Committee that satellite was not affordable:[94]
Of course for a lot of money I could get a two-way satellite link faster of course, but hardly falling into the category of affordable.[95]
A satellite system may soon become available from Optus, but has horrendous costs for very limited increase in speed - and NO promises from them either!!!.[96]
I rang Foxtel and asked to be connected to the satellite Internet network, but alas again, it requires another dish as it is a different satellite which controls the Internet network. We can't afford another dish.[97]
To have the same Internet speed as the rest of the civilised world also costs a premium. We cannot get normal broadband cable so it requires us to install a satellite to use in conjunction with a up connection. This service (according to Telstra's web site) costs $218.90 for installation, $70.95 a month plus up costs. The 2 way satellite service costs $399 installation, $699 hardware and at least $120 a month for the subscription. On the other hand, people just around the corner only have to pay for a cable broadband service which costs $259 for installation and then $54.95 a month with no dial up costs. This is an outrageous difference.[98]
2.77 Another issue for potential satellite users is latency. Unlike terrestrial services, data transmitted to a satellite has to be beamed up to the satellite and back to an earth station before being fed into the terrestrial telecommunications network. This causes a small but sometimes noticeable delay in the transmission:
While initially satellite looked to be a great solution to Australias vastly spread population, it was soon realised the technologys greatest enemy was price and the fact it was not suited to many applications sensitive to latency (delay). Such applications involving time sensitive data and multiplayer games could not be used across the satellite service. For these reasons satellite is not a popular choice.[99]
2.78 Wireless networks can provide high speed data transmission by using radio waves instead of fixed lines. There is a wide range of wireless technologies which can provide data services, the most common of which are the mobile phone technologies.
2.79 Existing second generation GMS and CDMA mobile phone systems provide low speed data rates of around 9.6 to 14.4 kbps. Higher speeds will be possible as these networks are upgraded. Existing narrowband 2G digital mobile phone networks can support data rates of up to 384 kbps although in practice speeds of 32-64 kbps are expected. 3G technologies offer the prospect of data transmission rates of up to 2 mbps for low mobility indoor applications. The most recent Australian Bureau of Statistics report on Internet activity identified only 3,000 mobile wireless Internet subscriptions.[100]
2.80 Wireless local area networks (WLAN) use low powered transmissions on class licensed spectrum[101] to transmit data over distances of 50 to 150 metres. They usually operate on the IEEE 802.11b or related standards which are capable of providing data rates of 1-2 mbps. WLANs can be used by consumers to establish their own local networks to connect devices in their own home or to other computer users nearby. They are also used by commercial operators to establish hotspots in public areas such as airports, hotels, cafes and convention centres. To connect to the Internet the wireless base station must have a connection using some other technology such as ADSL.
2.81 Wireless local loop (WLL) networks use radio access technology to link a customer to a local exchange or service provider. They can be used to provide broadband access to customers over a range of up to 40km and are particularly suited for use in large facilities or in regional areas.
2.82 To date wireless technologies have not played a significant role in providing access to data services in Australia. The second generation mobile phone networks provide only low data rates. Australias only 3G network was not launched until April 2003 and has only 50,000 subscribers.[102] Several companies have installed WLAN hotspots but this is a recent development and the technology is not in widespread use. Similarly, although some WLL networks have been installed there has been no widespread take-up of this technology.
2.83 The deliberations of the House of Representatives Standing Committee on Communications, Information Technology and the Arts inquiry into wireless broadband are outlined in Appendix 5. It is appropriate to reiterate its key conclusion that no wireless broadband technology is able to handle the data rates of the best wire-line technologiesthe solution to the last mile service involves a mixture of technologies, both wire-line and wireless.[103]
2.85 Bright Communications, in Western Australia, has trialled both fibre to the home and fibre to the kerb technologies and provides a variety of packages for home users offering speeds of up to 1mbps/256 kbps, and for business users a symmetrical service of up to 2 mbps. Telstra has also flagged its intention to work with property developers on a major trial of fibre-to-the-home technology in the near future.[104]
2.86 A variety of other technologies for delivering broadband are being developed or trialled. The most commonly discussed technologies use existing electricity supply networks to deliver digital data services. These technologies are described as powerline communications (PLC), powerline telecommunications (PLT) systems or broadband powerline (BPL) systems. The new broadband systems provide data rates of 4-20 mbps:[105]
PLC systems consist of terminal devices that are plugged into or attached to the electrical power supply network and allow data to be transmitted via the network to other terminal devices plugged into or attached to the network. The use of existing electrical power supply network wiring reduces costs and provides convenient access to broadband interconnection between devices.[106]
2.87 In a recent background paper the ACA noted that several European countries have adopted their own requirements for powerline communications systems and that there are a growing number of systems already being deployed in Europe and surrounding countries to provide last-mile broadband services.[107] The paper identified a range of issues arising out of the possible use of these technologies in Australia and the differences between the power supply network in Australia and those used overseas. These issues relate to:
2.88 In its summary the ACA said that:
Significantly, differences between the Australian powerline environment and overseas countries developing standards for broadband powerline communications systems might lead to "safe" limits in those countries being "unsafe" in the Australian context. This area would seem to need further investigation. In due course, developments in the UK might provide a valuable guide, because of the apparent similarities in the AC power supply networks of the two countries. However, there is a risk that overseas findings (and therefore standards' limits) might not be directly transferable into this country.[109]
2.89 The ACA stated that terminal devices for in-house applications have recently begun to be marketed in Australian and that an electrical supply authority has approached the ACA recently about the conduct of trials of equipment for last-mile applications.[110] However, it seems unlikely that this technology will become generally available to Australian consumers in the near future.
2.90 The price of broadband in Australia has frequently been criticised on the grounds that it is far more expensive than in comparable countries. The then National Office for the Information Economy, quoting Australian Bureau of Statistics figures, identified the high cost of access to the Internet as the main reason for households not having Internet access.[111] One reason given for the high cost of broadband in Australia was the very high cost of high capacity links:
A major cause for the high cost of broadband services is the cost of high capacity links. By comparison with other countries Australia has high tariffs for network capacity as shown by the graph in Appendix A. A number of small carriers have indicated that the first major drop in broadband prices (from more than $150.00 to approximately $100.00 per month) was due to Telstra dropping the cost of backhaul circuits.[112]
2.91 In early 2004 Telstra significantly cut its charges for ADSL. At the time of finalising this report the full effect of this change in prices was not clear. Telstra's competitors and the ACCC have raised concerns that wholesale prices have not fallen by a similar amount and that Telstra may be engaging in anti-competitive behaviour. These issues are the subject of ongoing discussions and their long term impact on pricing and competition in the broadband market is unclear.
2.92 Higher speed data services are available through a variety of technologies throughout Australia, but there is considerable variation in the broadband options and prices in different areas. In parts of some capital cities consumers have the choice of ADSL, cable, ISDN or satellite. In other parts of the same cities they are limited to more expensive ISDN or satellite because cable is not available and their fixed line connection will not support ADSL. In some rural and remote areas consumers are limited to satellite. Decisions about the roll-out of broadband in Australia have largely been made on the basis of commercial considerations and the resulting lack of uniform access to affordable broadband is a source of frustration to many consumers:
Senator Alston's comments that it is a commercial decision not to supply service to me and my family is not on in the year 2002.
Please go into bat for the little people like me who are discriminated against because we live in a home unit. Telstra should be giving service just as Optus should, not making commercial decisions not to serve the public who owns at least 50% of Telstra.
What type of commercial decisions will Telstra make if they become private?[113]
2.93 A common theme in the evidence to the Committee was that consumers in rural, regional and remote areas need to have the same level of access to the Internet as those in the capital cities:
We need to be able to have very similar, if not the same, level of Internet access available in the country as in the capital cities. This also needs to be at a similar cost if we are to be competitive with our city cousins.[114]
I firmly believe that, with regional situation such as Dungog, uncapped broadband (speed) capabilities could provide enormous economic stimulation to the area.[115]
More than anybody persons living in rural and remote areas need access to modern telecommunications services. Access to modern Broadband services could not only provide security and peace of mind to persons, but it could also be a major lifestyle improvement. However at this time the provision of these services at a comparable cost to persons living in the cities appears unlikely.[116]
We submit broadband should be regarded as a commodity similar to water and power therefore justifying some form of cross subsidisation to ensure competitive services are provided in the rural areas.[117]
2.94 The frustration of country residents is often shared by their city counterparts who might have no access to a terrestrial broadband service even though neighbouring suburbs have access to more than one technology. A Perth resident lamented the fact that residents in the suburb of City Beach have no access to broadband while those in the nearby suburb of Crawley have access to cable TV, cable broadband and ADSL.[118]
2.95 The frustration many consumers experience as a result of their inability to obtain access to affordable broadband appears to be aggravated by Telstra heavily advertising services which they are unable to access.[119]
2.96 The cost of broadband is also seen as an impediment to the more rapid take-up of broadband in Australia, as are the pricing structures. The lack of clarity in acceptable user plans[120] and the use of download caps are also seen as impediments to the take-up of broadband:
The current pricing structure where service is capped at 3gig by the two seemingly main providers where additional megabytes are charged at exorbitant rates by Telstra or being throttled to 28.8kbps modem speed by Optus could hardly be called a step forward and dont inspire the average Australian to connect to the Internet via broadband as they would in other developed countries with affordable connections such as the UK or the US.[121]
2.97 The evidence received by the Committee clearly shows that access to affordable broadband services is viewed as an essential service and that this service is not being delivered to all of the people of Australia. The Governments National Broadband Strategy will help to address this issue by making broadband more available and affordable for some consumers. However the Committee does not believe that it represents a comprehensive solution to the problems identified by this inquiry because:
2.98 The Government's various access programs are discussed in more detail in Chapter 4 of this report which also discusses the 'doughnut' of poorer service areas created by Government programs aimed exclusively at the most disadvantaged geographic areas.
2.99 In the Committees view, the Governments piecemeal approach to data services is unlikely to meet the needs of the community and may act as an impediment to Australias economic development. Access to fast, affordable, reliable data services should be accorded the same importance as access to voice services.
2.100 Pair gain systems are a significant impediment to the delivery of the full range of modern telecommunication services to many consumers.
2.101 Pair gain systems enable multiple standard telephone services to be carried over a smaller number of transmission links. They are employed throughout the Telstra network wherever there are insufficient copper pairs to meet the current demand for services. Telstra currently uses 16 pair gain systems which range from small units which allow two telephone services to be operated over a single pair of copper wires to large systems which allow up to 480 standard telephone services to be provided by connecting them to an exchange over single optical fibre cable. The advantage of a pair gain system is that it offers a cost effective alternative to laying additional copper cable where the existing infrastructure is inadequate.
2.102 Most pair gain systems are not able to provide the full range and standard of services which can be delivered over a normal copper pair. Restrictions on the standards of service imposed by various pair gain systems include:
2.103 One type of pair gain system - 16/96 - is used to provide up to 96 telephone systems by switching calls through only 16 copper pairs. The Tasmanian CEPU made the point that with this system, if eight of the 96 customers on such a system were to phone another eight customers connected to the system that would exhaust the available capacity leaving up to 80 customers without access to a telephone service.[122] In its submission the CEPU Tasmanian Communications Branches identified 12 areas where pair gain systems were affected by congestion but where there was no known relief in either funding or other action to ameliorate the situation.
2.104 Similar congestion problems were reported in relation to the number of transmission lines available at Digital Radio Concentrator Systems (DRCS) exchanges.[123] It should be noted that DRCS is a solar powered communications system designed by Telstra for voice and very low speed data applications in remote areas but, as an ageing technology, is currently being replaced under Telstras Remote Areas Telecommunications Enhancement program (RATE) with High Capacity Digital Radio Concentrator Systems (HCRC).
2.105 In some cases customers obtain a second telephone connection to provide a separate line for a fax or Internet connection, or to reduce reliance on a single line in case of emergency. Some customers in this situation are perturbed to subsequently discover that their second line has been connected through a pair gain system which leaves them with the same inadequate or vulnerable service which they were hoping to avoid by having a second line connected. In effect they are paying the full price for two lines but receiving two inadequate services using the same line:
My new service took twice as long to install as they said and was connected to a RAM 8 system at that stage I had no idea what that was but I soon found out. As both my lines run off the same RAM 8 if there is ever a problem with this unit both my lines are out of action.
It appears that because my service is so far from the exchange this RAM 8 needs a battery back up somewhere between the unit and the exchange they seem to record where they put the RAM 8s but the service personnel state that there are hundreds in my area and no record of the battery locations has ever been kept. Thus if there is a problem they could look at hundreds of batteries not knowing which one is attached to which RAM 8. My phone service has since this RAM 8 was installed continually cut in and out and unless I actually go to use the phone I do not know if it is working or not.[124]
2.106 The Boulding case[125] is one of the more notorious examples of the pitfalls of pair gains. The Boulding family had requested a second line to their home to ensure that they had a reliable service in case of an emergency, although Telstras records show that Telstra understood that the second line was requested to provide an Internet connection. Telstra installed the second line by using a Telespect 2 Digital Pair Gain System which used a digital signal transmitted along the single copper pair serving the Boulding residence to provide both services to that home.
2.107 Although the actual cause of the fault on the day of Sam Bouldings fatal asthma attack has not been identified, an investigation into the telephone services provided to the Boulding family was critical of the use of a pair gain system on that line:
The technical characteristics of the Kergunyah customer access network (CAN) infrastructure, in combination with the digital pair gain system providing services to the Boulding family, were not conducive to long-term reliable service in this instance. These technical characteristics around the time of January 2002 were not consistent with those recommended by Telstra for the type of electronic equipment installed on this infrastructure.[126]
2.108 Pair gain systems also impact on dial-up access speeds on fixed line networks. In evidence to the Committee about the general impact of these systems, Telstra stated that:
The main issue is that the broad delivery of service is really not impacted upon. Some aspects of services, as we all know, are impacted on to some extent - for example, different generations of pair gain equipment can have an impact on dial-up data speeds, but that also is a very complex area and depends on the length of lines, type of pair gain equipment and so on. By and large, you can still operate dial-up data through pair gain systems, but you get some slightly different performance outcomes, depending on the particular type of system.[127]
2.109 Telstra provided the Committee with the following table showing the capability of various pair gain systems.

2.110 As the preceding table shows, some pair gain systems effectively limited dial-up speeds to 7.2 kbps while many others, including the common early Remote Integrated Multiplexers (RIMs) limited dial-up speeds to around 26.4 kbps.[128] It was explained to the Committee that these limitations often relate to the number of analogue to digital conversions which occur when older systems are being used:
the bigger issue that impacts on data speeds is this factor of analogue-to-digital conversions that you get when you go through some of the access network electronics. Each time you go through an analogue-to-digital conversion you limit the achievable dial-up speeds. So if you have two conversions you are generally down to around the 30- to 28-kilobit per second level.
Most of the pair gain systems that we have used for many years have those two analogue-to-digital conversions. The way we have approached that issue is that, with the advent of the Internet assistance program, we are advising customers to access that program. If they have issues around the data speed then they can be brought up to the achievable levels that they need by case-by-case attention. That is working quite well. We are actually achieving quite a lot of very positive outcomes for customers who go through the centre.[129]
2.111 Telstra also advised that the RAM 8 phase 3 pair gains system would soon enter service. This system will offer 50 kilobit per second dial-up speeds and will be an important tool in further targeting some of the existing concentrator systems.[130]
2.112 The issue of whether customers whose dial-up speed was limited by a pair gain system should be paying less for their service was raised with representatives of the Consumer Telecommunications Network:
I think they should be. That is absolutely the case because it is quite clear they are never going to get something faster. I must admit that I was a little bit disappointed with the recommendation in the Estens report that the guaranteed speed be 19.2 kilobytes per second, especially considering that the standard modem for dial-up even is a 56K modem. The reality is that we know most of those modems are not going to get 56K and we can accept that, but perhaps 33.6 might be a more realistic speed that we are looking at. At least at that point you can guarantee to get decent email with some attachments, which is a bare bones basic service that you should be able to expect from an Internet service in Australia.[131]
2.113 The use of pair gains systems in the Telstra network also significantly impacts on the availability of ADSL. Telstra told the Committee that about 900,000 telephone services are currently provided through a RIM. Of those services, approximately 70 per cent are connected through exchanges which are ADSL enabled.[132] A significant number of Telstra customers are therefore unable to access ADSL services even though their exchange is ADSL enabled:
Ozemail informed me that they regrettably cant provide a service as my new phone line was not put in by adding new copper pairs as I was informed, but by using a RIM system which is incompatible with ADSL. At no time was I informed by Telstra that this would be a problem in the future, if I wanted to upgrade to broadband.[133]
2.114 There sometimes seems to be some confusion, even from Telstra personnel, about the reason that ADSL is unavailable on a particular service. One customer recounted his experience in trying to obtain an ADSL connection:
On 5 June I rang the 1800 151 311 number as per the advertisement in the Courier Mail to obtain my "faster affordable Internet experience", only to be told that, despite my close proximity to the centre of a large regional centre like Toowoomba, I was unable to obtain an ADSL connection because we have "a pair gain phone line system", and, "You can't expect to just ring up and get that sort of service like you would a telephone
I made contact with the electorate office of my local member of parliament and dealt with a very helpful aide who made contact with the local Telstra Countrywide office. One of the Countrywide staff then rang me back to correct some of the miss-information that I had been given during my previous telephone contact with Telstra. It appears that we have standard telephone lines, but are unable to access ADSL because we have a line length of 4800 metres, and the service will only reliably work up to a line length of 4000 metres from the telephone exchange.[134]
2.115 The Committee took up this issue with Telstra:
The short answer to your question about the RIMs is that we are actually no longer deploying RIMs. We have stopped that. We do not buy them anymore. They are not manufactured anymore. We are now deploying CMUX technology, and the CMUX-AU is the version of the CMUX that is designed to take up from where the RIM was formerly utilised. It is a device that handles the same sort of capacity of PSTN and ISDN that RIMs were able to provide for, but it has also been designed to provide broadband capability to a percentage of the customers in that area. Those devices have been deployed from earlier this year - early in the first half of this year - but when we first got access to the technology from the vendor it only had PSTN capability. ISDN was proven in a pilot phase, and that is now available in the market. The broadband capability of the CMUX-AU is being piloted this month in one exchange area of Queensland. Subject to that being a straightforward exercise, which we are reasonably confident it should be, we will have the broadband capability available in the new subdivisions in which we deploy these devices[135]
2.116 After this statement became the cause of some press discussion based on apparently contradictory evidence given by the companys representatives at another Senate committee inquiry, Telstra advised the Committee that some RIMs were still being deployed in special circumstances.
2.117 Telstra also advised the Committee that it was trialling a miniMUX system which could be fitted to an existing RIM to provide a limited number of broadband connections. A miniMUX provides 24 ports for ADSL and up to two miniMUXs can be installed in a RIM. The installation of a miniMUX is, however, dependent upon there being both sufficient demand and space to install the equipment in the RIM cabinet. Telstra outlined the status of the trials for the Committee:
This relates to a pilot period of assessment of miniMUX capabilities and the processes that relate to Telstras provisioning and maintenance of wholesale and retail services through these miniMUX devices. We instituted a trial in four RIM areas in the Crace exchange area in Gungahlin and surrounding suburbs early this year. We later extended that trial to encompass another six exchanges, three of which were in the Townsville area and three of which were in the Castle Hill/Kellyville area in north-west suburban Sydney.
Part of the reason for the trialthere were a couple of reasons, reallyis that there were some technical aspects of the performance of miniMUX inside a closed cabinet out in the street environment in relation to heat loading and so on that had to be assessed. There are four different types of RIM cabinets. Each one is slightly different, so the mechanics and physical performance had to be checked. That has proceeded to our satisfaction in that technical sense.
The integration of our provisioning processes and our maintenance processes has been worked through and tested in the different areas, so there is no issue in respect of where a miniMUX might be. We have a performance guarantee period for new technology that we then implement so that our operational part of the company is well satisfied they can operate that equipment well. That period comes to an end this week, so we are expecting formally to complete the trial and begin the commercial deployment of miniMUXs where it is appropriate, from this point on.[136]
2.118 Telstra advised the Committee that other methods of addressing the problems posed by pair gain systems have been to use one CMUX to provide ADSL services in an area with RIMs or to use available copper in the same area.
2.119 The Regional Telecommunications Inquiry (RTI) recommended that Telstra should give a formal undertaking to the Government including providing timeframes in relation to any action required to implement a strategy for improving the quality of telephone service affected by the use of 6/16 and similar pair gain systems.[137] In response to this recommendation the Government said that Telstra would provide it with a formal undertaking on 'its strategy, including timeframes, to improve, as soon as possible, phone services affected by the use of 6/16 and similar pair gain systems'.[138] An undertaking on this issue was signed by Telstra and the Commonwealth on 18 December 2003.
2.120 Subsequent examination of the undertaking between Telstra and the Government and questioning of Telstra during estimates hearings has exposed the limitations of the undertaking. The undertaking between Telstra and the Government deals only with problems of congestion on 6/16 and similar pair gain systems. It does not address the issue of the inability of these systems to provide access to ADSL, or to the same level of service in relation to calling number display and faxstream services[139] as other customers enjoy. When Telstra was asked whether it was only removing these systems when services degrade to a point that it is not a quality service a Telstra representative replied that:
We remove them when there is a very clearly agreed set of criteria based around the congestion performance.[140]
2.121 The RTI also recommended that:
Recommendation 4.2
Telstra should be required to demonstrate that it has an effective strategy to address any dial-up data speed issues arising from poorly performing pair gain systems. Telstra should provide a formal undertaking to the Government in relation to any actions necessary to implement such as strategy.[141]
2.122 At the time that this report was being prepared the Government had not secured such an undertaking.
2.123 Telstra has indicated that it is phasing out the older systems and that the newer systems being used have greater capabilities. During the final hearing on this inquiry on 7 August 2003 Telstra advised the Committee that, for example, it is phasing out the 6x16 medium line concentrators and that last year 520 of those systems had been removed.[142] More recently Telstra has stated that it has removed 670 of these systems and that about 5,600 remain:[143]
The use of the network reliability framework now clearly identifies where there are problems in the network, and then the remedial plans will go accordingly. If during that process we have identified that a pair gain system, whether it is large or small, is the cause of a problem from a customer perspective, that is where those plans will be built. That is the way we will prioritise it.[144]
We do not have specific time frames against specific types of pair gain systems, except to say that all the older systems - and I would refute the term archaic; they are just older - are all decreasing in their installed base, every one of them. I will mention that the 1+1 FM system has basically gone in the last year.[145]
2.124 In the Committee's view the continued use of outdated pair gain systems which impede access to services is not acceptable. Customers should be entitled to know if the level of service on their line is affected by the presence of pair gain systems and these systems should be phased out as soon as possible.
2.125 As the current Universal Service Provider, Telstra is required to ensure that payphones are reasonably accessible to all people in Australia on an equitable basis, wherever they reside or carry on business.[146] Payphones are also provided by other private operators, however. Concerns were raised with the Committee about the availability of payphones and some aspects of their operation.
I live just 100ks from Melbourne, Half way between Ballarat and Daylesford, .
Recently Telstra opted to remove the nearest Public Phone which was 6ks from our home and we now have to travel to Creswick 17ks away to use a Public Phone to report any faults with our home phone. A fairly frequent occurrence in this area. So much for increasing services to Country people.[147]
2.126 And:
Council is also concerned about telephone access at major tourist attractions. In this Shire, there are major water sport/recreation facilities that are widely used by locals and tourists alike. Unfortunately, should there be an accident, there is no public telephone (or mobile phone) access at the lake, so making emergency communication difficult.[148]
2.127 Concerns were also raised about payphones not giving change.[149]
2.128 Following the conclusion of the Committee's hearing program, the Australian Communications Authority reported to the Minister for Communications, Information Technology and the Arts on its review of the provision of payphones in Australia. In relation to the adequacy of payphone services the ACA found that:
existing payphone services in Australia are reasonably adequate and overall customer satisfaction is rising. In particular, the number of public payphones remains fairly stable.[150]
2.129 However, the ACA raised concerns about the reliability of Telstra's payphones and its fault repair performance:
the overall reliability of Telstra's payphones and its fault repair performance is poor in remote Australia, especially but not only in remote indigenous communities. There are steps that Telstra can and should undertake to improve the reliability of its payphones. The ACA will undertake closer monitoring of USO performance by Telstra in these target areas.[151]
2.130 The ACA made a total of thirty three recommendations aimed at improving payphone services, particularly for indigenous Australians and people with a disability, improving processes for determining the location of payphones, and improving Telstra's fault repair performance with regard to payphones. As the ACA's report was released after the conclusion of the Committee's public hearing program, the Committee has not had an opportunity to examine its findings or to seek comments on them from interested parties. The Committee has not, therefore, reached any conclusions nor made any recommendations following on from ACA's recommendations. Its findings in relation to people with a disability are discussed in the following section.
2.131 People with disabilities often require special equipment to allow them to access the telecommunications network. The Telecommunications (Consumer Protection and Service Standards) Act 1999 requires that the supply of a standard telephone service by the universal service provider, currently Telstra, include the supply of other equipment to people with disabilities, such as access to mobile phones and telephone access at public venues, in order to comply with the provisions of the Disability Discrimination Act 1992.
2.132 Several witnesses suggested that the current regulatory regime does not adequately address the changes occurring in telecommunications in Australia, that existing telecommunications legislation should be reviewed to ensure that it reflects new developments in technology, and that the resulting services on offer to the general public remain accessible to people with disabilities:
As alternative telecommunications technologies are introduced, it is time to ensure that the quality and safety standards that Australians expect are not eroded. Telecommunications legislation needs to accurately reflect the broader obligations of telecommunications companies, especially in relation to the needs of people with a disability.[152]
But I do believe that it is time to go back and review the legislation, to look at the definition of a standard telephone and at how we define the obligation to provide access for people with disabilities and to make sure that these kinds of black holes do not occur in the future. One of the ironies is that the previous legislation is basically technology specific. We need technology neutral legislation which enshrines the basic right of access to telecommunications for people with disabilities. That is our primary recommendation to you.[153]
2.133 A similar plea was made in other submissions with respect to consumers more generally and not just those with a disability.[154]
2.134 Australian Communication Exchange Ltd (ACE) provides the National Relay Service on behalf of the Commonwealth Government. The service exists under legislation to provide telecommunications access for people with disabilities, particularly people who are deaf or have hearing or speech impairments. It is a vital and important service, as it gives people who would otherwise be denied access to the network the ability to communicate with the general community. ACE submitted[155] that the introduction of wireless local loop (WLL) in regional and rural areas places Telstra in breach of its USO, because the technology is incompatible for Teletypewriter (TTY) users and thus effectively reduces their communication options in comparison to with those of the general public. The Australian Communications Authority disagrees, however, considering that Telstras approach to rolling out CDMA WLL services will fulfil Telstras obligations under the USO and the Determination. The Authority did acknowledge, however, that emerging technologies could possibly require changes to regulatory requirements.[156]
2.135 Equipment for people with disabilities is usually provided at present through the Disability Equipment Program (DEP) operated by Telstra and provided as part of its Universal Service Obligations (USO). This program was criticised by a number of witnesses representing people with disabilities.
2.136 First, they were concerned that the DEP is offered solely by Telstra (although Optus provides some equipment for customers using the Optus cable). Consequently, it was suggested that people with disabilities are being denied the full choice of telecommunications services and the full advantages of competition policy.[157]
2.137 Second, it was claimed that only limited equipment is available through the DEP, it is chosen solely by Telstra and much of it is dated:
In some respects the protection of our entitlements has become fossilised at the technology stage we had reached in 1997. Equipment for people with disabilities has not kept up with new technologies, and in some respects people needing adaptive devices are now further isolated than they were ten years ago, despite the enormous potential of new communications technologies to overcome the barriers of disability.[158]
2.138 Some submitters expressed concern that Telstra was able to vet access to the DEP:
To get equipment from Telstra I have to get a doctors signature, which seems quite reasonable, but then I have to be vetted by the operator at the disability inquiry hotline. What knowledge do those operators have of hearing loss or any other disability? [159]
2.139 To overcome these concerns, a number of disability representatives suggested that the DEP should be independent of Telstra, or indeed of any carrier:
an independently run disability equipment program would be really important. The consumers would be free to go to it, and they would not need to have a Telstra standard line into their home.[160]
The comment from the whole of the disability sector is: why do Telstra, or any other carrier, choose which equipment is available and which is not? That is why we believe the independent solution is the best, both for vetting and for the supply of equipment, so it can be decided on fairly what should be on the equipment list and it should be allocated fairly and reasonably.[161]
2.140 Attached to the submission from the Deafness Forum of Australia was a paper by TEDICORE (Telecommunications and Disability Consumer Representation) outlining the following key principles for such a program:
2.141 TEDICORE favoured the introduction of a public procurement policy for disability equipment to facilitate the access of people with disabilities to appropriate telecommunications equipment:
we really would like to see a big change in the way disability equipment is provided under an independently run program.
We consider that that [public procurement] is a very important issue that we would like to continue stressing as a way of encouraging more accessible equipment being available in Australia through the government taking a proactive role by ensuring that it specified in its public procurement policy that it would prefer tenders which included accessible equipment, as is happening in the United States at the moment.[163]
2.142 Telstra disputed claims that the company offered only a limited choice of equipment to people with disabilities:
Our view is that we do offer a comprehensive range of equipment that you [the disabled] can get through the program and we do undertake our customer satisfaction surveys to ensure that the equipment we provide to customers is meeting their needs and expectations.[164]
2.143 Its representatives advised the Committee that Telstra had recently revised its catalogue of products and services for people with a disability and they provided the Committee with a copy.[165] They also outlined some of the steps Telstra is taking to improve the range of equipment available for people with a disability:
More recently we have announced Braille and large visual display TTYsthat is in a flier that we circulated amongst the deaf and/or blind community; we launched that not very long agoso the equipment program has been expanded. As well as that we are developing a multifeatured disability phone. In the hearings you would have heard that perhaps a big button phone would be useful for some customers. We recognise that and that is what we are working on. We hope to have it available late this year. We are certainly working hard to achieve that time line.[166]
2.144 Telstra representatives also informed the Committee that it had established a wholesale program which would allow other service providers to offer disability equipment to their customers:
Telstra Wholesale established a disability equipment program in January 2003, so this is a fairly new initiative. It allows service providers to supply specialised telephone disability equipment to eligible customers in order for them to access the standard telephone service. Under this wholesale program, the full range of disability equipment that is available through Telstras program is also available to those service providers who might want to offer that service to their own end usersthat is, their own customers. Telstra has established a disability wholesale help desk for the service providers.
Since that program was establishedand I again say it was just at the beginning of this yearit has received about 650 calls and has processed 37 applications on behalf of service providers.[167]
2.145 Many people who are deaf or hearing impaired rely on a teletypewriter (TTY)[168] to communicate. Their opportunities for full communication are limited by the number of TTYs located in public places:[169]
if it is necessary for a particular individual to be issued with a TTY for use in the home then clearly it is necessary for that person to have access to TTYs wherever they go. This means that TTYs should be provided as necessary as part of the Australian communications network.[170]
2.146 This is a particular concern in the case of emergency calls:
One particular area of concern relates to emergency call services. While the emergency call service number 106 has been established as an alternative to 000 for TTY users, that does not solve the problem if the telephone service does not support TTYs problems arise for TTY users when they are away from home where they have a TTY.[171]
2.147 The Australian Communications Exchange referred to the TTY technology used by people with disabilities in Australia as end of life technology, isolating people from developments elsewhere:
Teletype devices were literally recovered from disuse in the late 1960s and refurbished and modified to become the first TTYs used by deaf people. Deaf people chose an end of life technology as their platform because it was available, cheap and it worked. TTYs in current use in Australia have a very similar form factor to those introduced in Australia in 1980.
Thus Australia is a TTY island using a system not deployed extensively anywhere else in the world.[172]
2.148 Other hearing impaired people rely on volume control on their phones. Few public payphones have volume control. These are therefore inaccessible to hearing impaired people:
One of the major problems for Australians with a hearing/deafness disability is the lack of access to volume control voice phones when away from their homes. If it is necessary for a particular individual to be issued with a volume control voice phone with a hearing aid coupler for use in the home, then clearly it is necessary for that person to have access to volume control voice phones with hearing aid couplers wherever they go.[173]
2.149 It was suggested that increasing the availability of volume control would transform the lives of many hearing impaired people:
The simple addition of volume controls would make all the difference to the ability of hearing impaired people to move freely around the world. We talk a lot about TTYs, which are vital and high-tech, but simple volume controls would change the quality of life of millions in Australia. [174]
2.150 Even where available, the volume control on public phones in Australia is inadequate for people with significant hearing loss, and inferior to the volume control available in some other countries:
Unfortunately, saying that payphones should have volume control is not sufficient. The loudest volume available on existing payphones in Australia is insufficient for anyone with close to severe hearing loss and is well below the best overseas payphones.[175]
2.151 Access to payphones by people with physical disabilities can also be limited by their location and their height, which may place them beyond the reach of people in wheelchairs:
The height and access to payphones continue to cause significant concern to people with physical disabilities. Many payphones are still not accessible in terms of height, and in terms of being able to gain access to the phone itself, particularly for those with limited upper limb dexterity.[176]
2.152 Concern was also expressed that deaf and hearing impaired people relying on TTYs were adversely affected by the phasing out of the analogue mobile phone service network and its replacement by GSM and CDMA phones. Currently they cannot use their TTYs to communicate by mobile phone, a significant limitation given that there are now more mobile phone connections than fixed line connections in Australia:
Both GSM and CDMA phones effectively garbled the signal of the TTY when it was sent across the telephone network, and they have lost that access We are saying that a large number of people in Australia who rely on text telephony are not able to get access to over half the network.[177]
2.153 While deaf and hearing impaired consumers can, and do, make use of mobile phones for text messaging, cost is claimed to be an issue for many.[178] Because of these developments it was suggested by some witnesses[179] that the quality of access to equipment and services by people with disabilities has been substantially degraded over the last five years. Others stressed the importance of ensuring that future developments do not similarly disadvantage people with disabilities:
Let us look at what is going on in technology and make sure that deaf and hearing impaired peoples interests are considered first, not afterwards, when they have to make complaints through the DDA to get their needs met.[180]
2.154 A number of witnesses commented on the adverse impact of Telstras closure in 2003 of its six aged and disability centres. These were said to have played an important role in informing consumers with disabilities of the range of equipment available and in advising them, generally on a one-to-one basis and often in their homes, of the equipment best suited to their needs. It was claimed that the centres were closed without consultation with the disability sector. They have been replaced by a disability hotline, an inadequate substitute in the view of some witnesses:
The alternative arrangements put in place by Telstra are not satisfactory. The use of the Telstra disability hotline a telephone service as the primary source of assistance for people with disabilities is not really a satisfactory substitute for the human contact of a telecommunications expert matching the needs of a person with a physical disability. As a principal provider of disability equipment, this particular move by Telstra to close the centres is deeply regretted by the disability community.[181]
2.155 Telstra representatives advised that the closure of its aged and disability centres was prompted by their lack of support in the disability sector:
The reason we closed these centres is that we found that they in fact were not being used very frequently. On average we had about three visits per week to these centres. It seemed to us that we were not in fact meeting the needs of people with a disability. We have now changed our approach so that, for all intents and purposes, we are turning almost every Telstra shop into a shop whereby people with a disability will be able to get the sort of advice they need about what might be available for them. [182]
2.156 However, they did acknowledge that there was inadequate consultation with the sector about these closures:
We did brief them prior to the closure but I think their criticism in terms of perhaps the haste in which it was done is something that we recognise. Certainly, we did receive some criticism about the lack of consultation that occurred over the closures.[183]
2.157 Telstra drew the Committees attention to the steps being taken to address these issues,[184] primarily through its third Disability Action Plan.[185] Telstra has an ongoing program to review the location of TTY payphones and to investigate the feasibility of a robust TTY payphone attachment for outdoor locations.[186]
2.158 In October 2000 a major research program on physical payphone access commenced under the guidance of an independent steering committee. Telstra stated that it now has an ongoing program to ensure that payphones are mounted in accordance with the findings of that research. Telstra is trying to promote awareness of access requirements among suppliers and commercial site owners for both wheelchair users and the visually impaired.[187] The Disability Action Plan also states that payphones are being upgraded with an in-built hearing aid coupling device, volume control feature, language selection and large visual displays.[188]
2.159 Telstra representatives explained that, to overcome the problems faced by TTY users in accessing the mobile phone network since the phasing out of the analogue network, they will be offering alternative TTY accessible technology. This may take the form of the old copper wire service or radio with TTY capability.[189]
2.160 Concerns were raised by a number of witnesses about the potential for new technology and convergence to overlook the needs of people with disabilities, as happened in the move away from the analogue network (as was discussed above). As mentioned above in the context of Telstras universal service obligations, particular anxiety was expressed in relation to Telstras current consideration of the deployment of a wireless local loop (WLL) in regional and remote areas, as this technology is not accessible to TTY users:
The TTYs currently available in Australia will not work with a wireless local loop so access to the standard telephone service for Deaf people and people with a hearing or speech impairment will currently not be possible in an area serviced by a wireless local loop.[190]
Telstra has made it clear, and for what I believe are quite reasonable business purposes, that is will be rolling out CDMA wireless local loop in a range of scenarios as the standard telephone service. The quickest, easiest and cheapest way of getting networks rolled out there is to use wireless local loop. Wireless local loop is based on CDMA. It is not accessible for people with disabilities. So all of a sudden we are having whole chunks of our network cut out. We are basically punching black holes in that network for people with disabilities, which is not insignificant.[191]
2.161 Telstra has said that where wireless local loop is installed, the company will meet its obligations to people with disabilities by offering an alternate technology to residences and workplaces where there is a deaf or hearing impaired resident or worker. In the view of the disability sector this is an inadequate response since it will not take account of the future needs of people with disabilities who move their residence or workplace. Nor will it allow these people to access telephones outside their homes or workplaces, a service available to every other member of the general public. It was argued that, therefore, such an approach represents an abrogation of the major carriers responsibilities under the USO, as well as the requirements of the DDA.[192]
2.162 A further concern for people with disabilities is the roll-out of telephony using Internet Protocol, which is being progressively introduced into universities and some major public organisations such as CSIRO. This is also incompatible with TTYs:
It [Internet telephony or IP telephony] looks and feels like a regular telephone. It has a number. You pick it up, you dial and it works. But it does not work with TTY. In fact, it will not work with any modulated modem type device. So again, we are now looking at areas the size of cities, whole universities in fact, not just some but nearly all universities losing their ability to be accessed by people with disabilities. So we now have a serious hole emerging in the telecommunications network for people with disabilities.[193]
2.163 The Australian Communication Exchange advocated the extension of the any to any connectivity now operating in relation to voice telephone services to text and video connectivity. These options will become more viable with developing broadband technologies. Any to any video connectivity will be especially valuable for deaf people who use Sign language as their first language:
Deaf people who use Auslan would also prefer to use it when communicating on the phone. With the growing introduction of videotelephony (video conferencing, videophones and Video over Internet Protocol) and roll-out of broadband, there is now every opportunity for Deaf people to at last use their preferred language to communicate over the Australian network.[194]
2.164 Some witnesses suggested that the benefits of the technology may be limited for some people with disabilities by the cost of the equipment required:
Consumers with a disability have a heavy reliance on telecommunications equipment and the increased impost [of Telstras recent price rises] makes it increasingly difficult to remain connected. The problem is even worse for consumers in rural and remote areas.[195]
2.165 Telstra representatives advised the Committee that the organisation is conscious of the potential for new technology to adversely impact upon people with disabilities if their needs are not adequately considered during the development phase. To prevent such an eventuality Telstra has ongoing discussions with the disability sector:
what we are always battling with in this area is that it is moving as rapidly as it is. That includes how to make sure that we are providing people with a disability with the ability to link into that new technology at the same time as it is being rolled out. We are very conscious of the fact that the disability community in general see this as being a very important point of principle.[196]
2.166 Telstra witnesses acknowledged, however, that its efforts are not always successful:
But to be absolutely honest with the committee, it is not always possible to do that, so we sometimes get into this dilemma of not knowing how long one can delay the roll-out of a technology that is required by the community at large, because one does not have available to an important part of the community a corresponding technology which will meet their needs. .. We try to work in advance of these new technologies, so it coincides with their introduction, but it is not always possible.[197]
2.167 They also pointed to the need, in developing new technologies, for Telstra to respond to demand rather than anticipating it:
Another assumption seems to be that Telstra can and should provide the infrastructure necessary to deliver the latest technology before genuine demand has been established for the services provided by this technology. I think we have to say that all organisations whether they are public, private or even not-for-profit - must ensure that their investments are somehow, to the best that they can manage them, synchronised with demand for their goods and services.[198]
2.168 Telstra is aware of concerns by disability advocates that developments in any to any connectivity might not adequately address their needs. It has established a Working Group to look at options and consumers and disability advocates are represented on that Group.[199] Telstra says that it is investing heavily in the broadband infrastructure necessary to support any to any connectivity in text and video, having spent $1 billion to date, with an additional $1 billion to be allocated over the next five years.
2.169 On 31 March 2004 the Government released the ACA's report on its review of the provision of payphones in Australia.[200] The ACA recommended that:
3. The payphone industry and disability peak bodies should consult through an Australian communication Industry Forum (ACIF) working group, and work together to develop a Payphone Accessibility Code for endorsement by HREOC. Australian Local Government Association (ALGA) and the Property Council should be invited to be involved in this ACIF group. The group should look for approaches that:
4. Telstra should continue to increase teletypewriter (TTY) payphone numbers in secure locations where there is evidence of need and TriTel and other specialist payphone firms should, at a minimum, provide TTY payphones in private sites when an agreement with the site owner requires Telstra to remove a TTY payphone. TTY siting criteria could be discussed in the proposed ACIF working group. The ACIF working group should also propose a means of providing comprehensive information about the location of TTY payphones. TTY payphones also need clear instructions displayed to explain how to use them.[201]
2.170 The Committee has not had the opportunity to examine the detail of these proposals. However, they are consistent with the evidence which was received by the Committee during its hearings and it supports the general thrust of the ACA's recommendations.
2.171 The Committee firmly believes that adequate communications are as important, if not more important, for the disabled as they are for the able-bodied. While there are telecommunications issues affecting the able-bodied who live in rural and remote areas which could be expected to be even more challenging for the disabled, the Committee was disturbed to learn that new technology represents an issue for the disabled even in major urban areas. The Committee also recognises the challenges for telecommunications providers to give appropriate priority to the needs of the disabled in such a rapidly changing environment, while noting that new technology has an inherent capacity to provide solutions.
2.172 In the Committee's view there is a strong case for the development of an independent disability equipment program. This would allow telecommunications users who are affected by a disability to access a service from a wider range of service providers and give them greater control over what equipment should be available.
2.173 The Committee accepts Telstras argument that the closure of its aged and disability centres was justified by their limited use, but expresses its disappointment at the poor manner in which the closure was handled. Apart from these issues, the Committee is satisfied that the needs of the disabled are generally receiving appropriate attention. There is no doubt, however, that such attention would be diminished in a fully competitive market without a continuing system of government regulation, with telecommunications providers aiming at ever lowered costs, rather than the provision of services which might not be justified on a fully commercial basis.
2.174 The background and operation of Telstras priority assistance service is outlined in Appendix 5. However, that program only extends to Telstras network. During the Committees hearings this issue was discussed by Telstra:
. you may be aware of what is described as the Priority Assistance Program, which is a program set up to enable us to meet the needs of customers who might have a life-threatening illness. Whilst that program is particular to Telstra at the moment, the government has asked other providers to consider making the same service available to their customers. There is quite a bit of discussion going on within the industry about how that might be done in a way which does not necessitate the government putting into place a licence condition on them to ensure that it happens.[202]
2.175 The availability of mobile phone coverage was raised as an issue in many of the submissions received by the Committee. Most of the evidence which expressed concern about the extent of mobile coverage was received from, or related to, rural, regional and remote areas. Much of this evidence came from local government bodies or organisations.[203] Some examples will suffice to give the picture:
Approximately 30% of our Council area is without Digital Mobile Phone Services. This includes the Townships of Swan Reach, Walker Flat, Purnong, Bowhill, Murbko, Mt. Mary, Keyneton, Tungkillo, parts of Palmer and the eastern Mount Lofty Ranges within our area (except adjacent to the Sturt Highway).[204]
That their mobile phones work EVERYWHERE and not only in certain areas so that when driving twenty kilometres the services appears and disappears.[205]
Our mobile phones continue to drop out in this area especially when travelling to and from Coffs Harbour. There are quite a few black spots around the area and we have purchased a CDMA phone to try and overcome the problem but still find that the phone drops out at certain spots.[206]
I live just 100ks from Melbourne, half way between Ballarat and Daylesford, we have never had a mobile phone service here and our mobile phones are only used when we are away from home. Service between our home at Ballarat are intermittent even when we are travelling toward Ballarat and Telstra readily admit to this.[207]
2.176 Concerns about the possible consequence of inadequate mobile coverage related not only to business and social needs, but also to the ability to seek help in the case of emergencies:
A recent tragic incident near the Scott River district south of Nannup illustrated this dramatically when a father and husband was unable to call for help when his wife and sons were swept from rocks into the sea.[208]
2.177 The Committee accepts advice that mobile phone coverage is continuing to expand. Many submitters acknowledged that mobile coverage in rural areas had improved, although it is still inadequate in places.[209] Telstra advised the Committee that it was continuing to expand its mobile coverage:
During the life of this committee we have also significantly expanded the size of our CDMA mobile phone network. Last financial year we added 402 base stations and repeaters. This has increased mobile phone network coverage from 15 per cent of the landmass to almost 19 per cone tot the landmass, with over 98 per cent of the Australian population now covered by Telstras CDMA mobile network. This financial year we plan to add a further 482 base stations and repeaters. This will increase mobile coverage to well over 20 per cent of the land mass by June 2004.[210]
2.178 Telstra also provided the Committee with information about the cost of providing mobile coverage and the economic viability of expanding coverage to smaller communities:
. It is not purely the cost of the base station but the back haul transmission capacity back to a base station controller, which is generally located in the capital cities. So, in the Queensland context, it is in Brisbane. That is a variable cost of course, depending on the distance and the availability of transmission capacity out there. In a general sense, though, if I can generalise, an economically viable solution runs out at a community of about 1,000 people.[211]
2.179 Telstra went on to outline the effect that Government programs have had in enabling coverage to be expanded to smaller communities:
Since then, of course, we have had the government programs of NTN and Besley that have helped to fund communities that are significantly smaller than that. At the bottom end, we are talking about communities down to about 380 people. Subsequent to that, again there has been some special funding from other organisations such as state governments that has helped us to provide funding for things like gaps in highway coverage et cetera. The last Queensland governments mobile contract included a condition for the provision of mobile phone coverage on some of our highways, and there are other examples of the same thing. The short answer is that, on a straight economic basis, you can look at a community of around 1,000this is for CDMA, by the waybut through various other programs there should be very few, if any, communities down below 380-odd people where we cannot provide a mobile phone service.[212]
2.180 However, the programs aimed at improving coverage have not been able to assist some communities because of their structure. In its submission the Shire of Nannup, in south western Western Australia, expressed concern about the poor mobile phone service in its area. As part of the Wireless West initiative that involves State, Federal and carrier involvement, two sites in its area were identified for mobile phone towers. Under the program the Council was requested to provide $20,000 per site towards the cost of the infrastructure. As the Council was unable to contribute to the cost, the sites will not be built. The Council expressed concern that local governments were being held to ransom in the site selection process and that the funding of telecommunications infrastructure is not a local government responsibility.[213] Telstra acknowledged that under the Networking the Nation program contributions from local communities were required:
Under the Networking the Nation program, there was a requirement for whoever was making the application to NTNand it was not always a council; it could have been another community groupto contribute $10,000. That is in the context of a base station that might cost in total half a million bucks or thereabouts. So, yes, there was a requirement under that program for that contribution to be made.[214]
2.181 Some submissions also noted that while the total extent of mobile coverage was increasing, the important issue for users was the coverage of the network to which they could gain access. In its submission the South West Development Commission stated that there was an expectation, especially by international visitors, that GSM mobiles will work throughout the region.[215] This issue was also raised in relation to programs designed to improve coverage on regional highways:
I find it quite untenable that tenders were requested from Vodafone, Telstra and Optus for Federal Govts $50.5 million program to improve mobile phone coverage on 35 regional highways.
With Telstra virtually the only provider of CDMA service (Optus offers CDMA on Telstra equipment), it would mean that Vodafone and Optus would be tendering for GSM service. As the carriers do not "speak" to each other (inter-carrier roaming) - a subscriber to Optus GSM cannot access service from a Vodafone or Telstra GSM tower and vice versa - it would mean that anyone wanting continual coverage would need to carry CDMA, and three GSM phones to access all carriers.
Intercarrier roaming is technologically feasible within CDMA and within GSM networks but is not possible between CDMA and GSM networks as the different technologies cannot interact.[216]
2.182 The South West Development Commission suggested that one solution to this problem would be the development of a dual use handset.[217]
2.183 While most of the evidence received by the Committee on mobile phone coverage related to the extent of coverage in rural areas some submissions also raised the issue of blind spots in mobile coverage in both city and country areas:[218]
Arriving in Brisbane, I expected almost a perfect mobile phone system . Alas, I can't use either of 2 mobile phones in my Unit, or outside in the yard.[219]
2.184 In response to the concerns about continuing non-coverage of more remote areas by its GSM and CDMA networks, representatives of Telstra noted the availability of its satellite service:
We still have TMS, our mobile satellite service, that covers the whole of the footprint of the country. So you can take that as an overlay network that fills in those gaps. It is not as if there is no service there; it is just a different platform that we use.[220]
