• 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

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.

• 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).

• 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

Analogue alarms may be transmitted less reliably

6

• 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 eg SCAIP & BS EN 50134-9

• Higher-value services enabled by a digital connection

Digital is the goal for alarm equipment

BUT, other digital TEC solutions need to be supported too

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

‘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

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

ALLALLALLALL----IP Test Guidelines: Categories of TestingIP Test Guidelines: Categories of TestingIP Test Guidelines: Categories of TestingIP 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.
