1 TSA The Impact of IP on Technology Enabled Care (TEC) Steve Sadler, TSA Associate & Chair of TSA Tech Advisory Group

2 Role of TSA s Technical Advisory Group How services can be developed, transformed and made more effective by technology HowmemberscanmakebestuseofTECSinthedeliveryoftheirservices,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 mayberequiredordelegatedbythetsaboard Extract from TSA TAG Terms of Reference

3 IP Readiness Guide Helping care services to understand the implications of procuring and operating in a digital environment. Helping technology providers to understand the demands of TEC, when specifying, designing or integrating digital solutions.

4 IP Readiness hot topics The change to IP introduces new network configurations and new failure modes: Will voiceband alarm signalling still work reliably? How will back-up power supply be managed? How will services fund the switchover of technology? TEC has broadened from alarms to include other assistive technologies The changes offer the prospect of increasingly proactive care services Richer datasets will be accessible, raising questions of information security Consumer awareness of digitally-enabled services is growing Self-management of health and care(by users/carers) plays an increasing role Real-time alarms will experience the greatest impact(social alarms, telecare). Other forms of TEC are already IP-connected(telehealth, social inclusion).

possibilities Tones used by telecare protocols pass through

5 Analogue alarms may be transmitted less reliably Telephone network is shifting to digital (IP) Huge number of call routing possibilities Tones used by telecare protocols pass through networks less reliably Some protocols are more resilient than others 5

Digital is the goal for alarm equipment Designed for modern networks Digital alarm data is much quicker to send Much more information can be communicated Devices are online connected

6 Digital is the goal for alarm equipment Designed for modern networks Digital alarm data is much quicker to send Much more information can be communicated Devices are online connected continuously Published interoperability protocols egscaip & BS EN Higher-value services enabled by a digital connection BUT, other digital TEC solutions need to be supported too 6

Barriers to take up of digital alarms Cost of replacing alarm devices and monitoring centre technology Long established analogue industry Digital not yet required by procurement Security concerns

7 Barriers to take up of digital alarms Cost of replacing alarm devices and monitoring centre technology Long established analogue industry Digital not yet required by procurement Security concerns from IT departments Safety and reliability concerns e.g. power back-up, service availability, quality of service under load Concerns about the connections in the home people are asking for Guidance

8 IP Readiness Guide How analogue alarms work How digital alarms work Drivers for changing to digital Benefits of digital alarms Considerations for choosing digital alarms Availability: Failover and redundancy Installation issuesor digital alarms Using broadband Using GSM Considerations for Alarm Receiving Centres Cyber security Plan to be published before the end of November

9 ALL-IP Testing Which existing alarm systems are affected and to what degree?

10 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

11 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.

16 Status and Next Steps - Technology suppliers already familiarising with BT test facilities, although full network combinations are not yet available. - Part I of a common test specification has been drafted by TSA TAG, and is in review. This Part I deals with analogue connected devices operating over IP and combination networks. - Part II, for IP-connected devices is in preparation. - Joint working proposed with NICC (Nov/Dec 18?), to create a joint test schedule for ALL-IP. - TSA staying close to Ofcom and other communications providers to establish links to other test facilities.

17 Mobile and Cellular Guide To assist an understanding of mobile and cellular as options for TEC connectivity, and to inform decision making

18 Mobile & Cellular Guide Topics include: - Multi-Networks - Roaming SIMs - Security Public Fixed IP vs Private - System & Service Availability - IOT - Mobile Broadband Final draft in preparation by TAG sub-group. TAG to review final draft shortly, with the aim of December-18 release.
