1 Hall 1 (Main Plenary) Wednesday 17th October 14:00 15:00 TSA TECHNICAL ADVISORY GROUP AN UPDATE ON DIGITAL CELLULAR COMMUNICATIONS

2 TSA Technical Advisory Group Update on digital and cellular communications Steve Sadler, TSA Associate Chair of Tech Advisory Group Paul Shead, TSA Chairman - Member of TSA TAG Oliver Cox - Member of TSA TAG

3 Focus of the Technical Advisory Group How services can be developed, transformed and made more effective by technology How members can make best use of TECS in the delivery of their services, and how technology can be exploited to gain benefits for all stakeholders How the industry makes the move to a fully digital infrastructure such that it does not disadvantage service providers and service users Creating a guide to relevant technical standards to support these objectives Advising and recommending the prioritisation and allocation of TSA resources Providing advice and guidance to the TSA Board on matters of technology as may be required or delegated by the TSA Board Extract from TAG Terms of Reference

4 IP Readiness Guidance Paul Shead

5 IP Readiness Guidance - Background Telecommunications networks are changing TEC is broadening from alarms to include other assistive technologies This shift offers the prospect of services which are increasingly proactive. The change to IP introduces new network configurations Richer datasets will be accessible, raising questions of information security. Consumer awareness of digitally-enabled services is growing self-management by users and their care networks plays an increasing role.

6 Analogue alarms are transmitted less reliably Telephone network is becoming more digital Huge number of call routing possibilities Tones used by telecare protocols pass through network less reliably Some protocols are more resilient than others 6

7 BT socket will be for a router, not a telephone Telephone connection in the home will change from analogue Designed for ordinary telephones to plug into Voice service, with data over the top.to digital Designed for a router to plug into Data service, with voice over the top 7

8 Example: New ALL IP service from BT Everything connects via a new Router Extensions fed from telephone socket cease to work ATA port gives dial tone and line voltage (Interim solution) Wireless DECT phones 8

9 Digital units are the only solution Designed for modern networks Digital alarm data is much quicker to send Much more information can be sent Devices are online connected continuously Published protocols eg SCAIP Extra services with a digital connection 9

10 Barriers to take up of digital alarms Long established analogue industry Digital not yet required by procurement Security concerns from IT departments Concerns about the connection in the home people are asking for Guidance

11 IP Readiness Guide: Purpose to help overcome the barriers to help providers of TEC services to understand the implications for procuring and operating technology when applied in a digital environment. to assist service providers in planning for changes to service delivery that are essential to digital technology-enabled care. to help technology providers to understand the particular demands of TEC, when specifying, designing or integrating digital solutions

12 IP Readiness Guide Contents: How analogue alarms work How digital alarms work Drivers for changing to digital Benefits of digital alarms New digital services in parallel

13 IP Readiness Guide Contents: Considerations for choosing digital alarms Failover and redundancy Installing digital alarms in the home Using broadband Using GSM

14 IP Readiness Guide Contents: Considerations for Alarm Receiving Centres Cyber security Glossary of terms Planned to be published before the end of November

15 ALL-IP Testing Steve Sadler

16 What are the issues? VoBB cannot guarantee to support those services that have historically relied on conventional (end to end) voice services Most obvious are that those that require baseband connectivity such as Redcare and related security applications More broadly, DTMF tone transfer will be affected in ways that may make some security and care alarms malfunction Such problems will also extend to fax machines and other devices that use voice band modems This problem is already evident to some degree with VoIP being used by some communications providers in their core networks Increased call failures are being reported, which appear to be due to how calls are routed through multiple networks This problem may also extend to other applications and will need service re-engineering and/or complete service/cpe replacement to rectify VoBB will not have the line powering capability of the PSTN Telecare and other non-voice services will need alternative power arrangements Industry All IP Event, Ofcom 23/3/18 PROMOTING CHOICE SECURING STANDARDS PREVENTING HARM 16

17 Testing Testing is unlikely to categorically prove that devices (e.g. alarms) will or will not work over new networks But they can offer valuable insight into the extent and scale of any issues This insight can help all parts of the industry Creating mitigation strategies, developing new products, training and augmenting support/call centre staff To get the greatest benefit, we need to get consensus across all parties as to: Network configurations End devices Connections to call centres Coordination is necessary to agree the most optimum set of test scenarios Ofcom believes it is well placed to undertake this coordination role And looks to all parties to support it through all stages of this process Industry All IP Event, Ofcom 23/3/18 PROMOTING CHOICE SECURING STANDARDS PREVENTING HARM 17

20 Summary of Potential Impact of ALL-IP Networks Characteristics of ALL-IP that potentially affect the operation of alarms include: No line powering No primary communication path in the event of local power failure Data discontinuities, which may occur due to: o dynamic jitter buffering o packet loss o interconnections between communications sub-networks o DTMF tone detection/re-generation End to end delays and synchronisation issues

21 ALL-IP Test Guidelines: Categories of Testing Baseline Tests: end to end testing over a single communications network provider, employing selected combinations of alarm and ARC equipment and protocol types across a TDM network. Network Combinations: different combinations of paired communications providers, varying network performance characteristics, only selected combinations of alarm, ARC equipment and protocol types. Alarm System Configurations: multiple combinations of alarm and ARC equipment types, employing nominal network performance characteristics. Fault identification: communications are disconnected and the ability of the alarm system to identify faults and recover is tested. Power Testing: loss of local power is simulated, alarm system response is tested.

29 Mobile Guide What is inside? - Multi-Network & Roaming SIMs - Security Public Fixed IP vs Private - Significance of Uptimes - IOT type SIMs vs Corporate contracts Mobile Broadband

30 Roaming SIMs Permanent Roaming Are you covered? 1. European Regulations Conditions - "Roam like at home" is intended for people who occasionally travel outside the country where they live or have stable links i.e. they work or study there. It's not meant to be used for permanent roaming. As long as you spend more time at home than abroad, or you use your mobile phone more at home than abroad, you can roam freely at domestic prices when travelling anywhere in the EU. This is considered a "fair use of roaming services". ** Roaming charges will no longer apply, as long as you are using your phone abroad temporarily. Providers can still charge you for using your SIM card in another country permanently All roaming charges for temporary roaming will be abolished on 15 June 2017 (fair-use rules are to be applied) 3. Vodafone UK standard T s & C s Inclusive roaming allowances are only for our UK customers who are on short holidays or short business trips to countries within our Europe Zone. If you re permanently roaming abroad for example, you continuously use your phone from within our Europe Zone for more than 30 days we may suspend international roaming on your account so you re no longer able to use your phone abroad. We ll contact you before we do this.

31 Security Public Fixed IP vs Private Shodan to easily find public devices.

32 Significance of Uptimes % 43 minutes a month offline % 1 minute 45 seconds a month offline - Uptime.is to calculate easily.

33 IOT type SIMs vs Corporate contracts Mobile Broadband Is there really a difference? A data-only SIM lets you stay connected on the move just pop it into your device all while you're out and about. You may only use your SIM card in modems, dongles, ipad, tablets and/or laptops If you do not we ll suspend your service, restrict your use or speed, or charge you for unauthorised use.

34 IOT type SIMs vs Corporate contracts Mobile Broadband Is there really a difference? You must not use your O2 SIM with applications that primarily transfer information between fixed systems and remote assets or any other remote computer systems. Using your O2 SIM in a modem instead of a mobile phone or tablet would fall outside this Fair Usage Policy

35 Mobile Guide - Update - Final draft underway following TAG review - The aim to give a broad understanding of mobile to inform Digital decision making. - TAG to review final draft shortly and aim for December-18 release.
