The move from analogue to digital is a significant evolution for the telecare, warden call and Technology Enabled Care sectors.
Telecare equipment needs to communicate differently as we transition from the PSTN to the new All-IP network, using updated protocols referred to as NOWIP and SCAIP. But what does this mean for housing providers?
In this blog post, we explain:
- What is a protocol?
- What protocols should be used in digital telecare?
- Can analogue to digital converters work with SCAIP and NOWIP?
- How to put the right protocols in place
What is a protocol?
A protocol is a specified set of rules and regulations that governs how digital information is sent and received between two points. It's essentially the language that telecare equipment uses to communicate with the monitoring centre over the telecoms network. By translating the protocol, the monitoring centre can then interpret who and what is calling them.
There are two main protocols used within digital telecare:
SCAIP (Social Care Alarm Internet Protocol)
An open digital social alarm protocol for dispersed alarms. This enables communication over the internet between dispersed Social Alarm devices in the community and a monitoring centre. SCAIP/Cenlac TS50134-9 is the latest version of this protocol, including guidance for encryption so it can be used safely over the open internet.
NOWIP(BS8521-2
A fully interoperable standard for grouped living schemes, establishing a common signalling protocol and compatibility between device manufacturers and Alarm Receiving Centres.
Protocols are often established and/or ratified by independent bodies, such as the British Standards Institution (BSI). This ensures consistency and standardisation, while also supporting innovation in the market.
What digital protocols should be used in digital telecare?
Some manufacturers may use proprietary protocols rather than the open, standardised ones. For example, Tunstall created their own analogue protocol to connect to their own monitoring centre, which means that individuals with Tunstall telecare equipment are not able to outsource to other manufacturers. This makes it very difficult for those looking to upgrade to digital.
It's therefore important to check your manufacturer is compliant with SCAIP or NOWIP.
The TSA provides guidance on what protocols to specify:
- TS50134-9 (for dispersed alarms) and BS8521-2 (for grouped living schemes) are recommended to “maximise digital interoperatbility”.
- SCAIP should be required as a minimum “with a clear expectation of when TS50134-9 should be available for deployment with financial penalties to the manufacturer for failing to meet the agreed deadline."
This ensures the device you're investing in is compatible with alarm receiving centres capable of receiving industry standard digital alarm protocols, while also providing a seamless digital connection over the upgraded digital telecoms network.
Do analogue to digital converters work with SCAIP and NOWIP?
You don’t need to replace all your legacy analogue hardware today in order to use SCAIP and NOWIP. If you’re unable to complete a full upgrade before the switchover, analogue-to-digital (A2D) converters can offer a highly practical solution.
A2D converters:
- Translate the signals sent by your existing analogue equipment into a format the new digital network can understand.
- Act as a bridge, allowing your current devices to communicate safely and reliably using the standard protocols described above.
- Guard against safety risks, keeping residents connected without any disruption to their equipment during this transition period.
However, if you opt to use an A2D converter, it's important to confirm this supports the key SCAIP and NOWIP digital protocols and is compatible with your alarm receiving centre.
How to put the right protocols in place
Digital protocols such as SCAIP and NOWIP are the new norm for the digital telecare industry. This means all dispersed alarms and warden call systems should be using these to create a safe, reliable and fast connection.
- For dispersed alarms:
Specify SCAIP (TS50134-9) as the minimum requirement. - For grouped living:
Specify NOWIP (BS8521-2). - For A2D Converters:
If opting for a converter, explicitly confirm it supports key digital protocols like SCAIP and NOWIP. - For Your ARC:
Ensure your chosen equipment or converter is compatible with your specific Alarm Receiving Centre.
With the right protocol in place, manufactures in the technology enabled care sector and housing providers will benefit in the long term, keeping residents safe and secure whilst living independently.
