Call failures to alarm receiving centres in the UK are rising but the reasons for this are currently the subject of hot debate.
The problem is linked to the roll out of the next generation network (NGN) replacing the UK’s analogue Public Switched Telephone Network (PSTN), a task which will be complete by 2025.
What is not debatable is that 1.7m of the most vulnerable in our society are being placed at risk as calls to alarm receiving centres (ARCs) increasingly fail or are delayed in their delivery due to incompatibilities of existing technologies.
At the Telecare Services Association (TSA) conference in November 2017, technology-enabled care services company Appello, with circa 100k telecare system users, identified a 7.5 percent call failure rate and announced the problem as “deeply worrying”.
At the same event, Communicare247 presented a report which highlighted a significant 12.3 percent spike in call failures identified by Falkirk Council. This was part of an ongoing analogue to digital assessment program operating across 12 percent of the existing Scottish telecare user base, and significantly this spike occurred in Falkirk within a short three month period. Both Falkirk Council and Appello have published their evidence of increasing call failures in a TSA whitepaper.
The TSA white paper, A Digital Future For Technology Enabled Care, highlights that the 1.7million people in the UK reliant on telecare need answers as their service is “threatened by disruption as UK telecommunications shift from analogue to digital”.
Yet the link to call failures and the rollout of NGN has been called into question by a major equipment provider. In a recent blog, they asked a very challenging question: Are network issues causing a greater number of alarm call failures?
Their answer delivered by the blog was, in essence, ‘maybe not yet’.
In a comparison between one ARC, where call failures were high versus another where they were low, the blog claimed that “while the use of NGN networks has grown in the last few years this cannot account for the increasing trend”.
As a potential compromise, the author also said that they could overcome any potential issues through the use of hybrid terminal adaptors (ATAs).
However, evidence both in the UK and Sweden plainly demonstrates call failures increase as the network switches to digital. (more…)
