Medical Alarm Dialers?

 

“Medical Alarm dialers” or Alarm Security phones as they are called in Sweden were "invented" by the end of the 70th century by Jan-Erik Larsson from Sweden. Like all telecommunications products at the time, they delivered the duress solutions to the homes of the Swedish people via Swedish Telecom. Of course, much changed since then, but the basic function remains the same.dialer

Today, we are in the midst of a changing global telecommunication environment therefore we are also changing our views on the importance of personal duress and medical alarm security.

It is important to distinguish between concepts such as analog and digital.

  • An analog phone is the traditional home phones we have used for almost 100 years.
  • Digital technology involves the transmission of data via a network based on Internet Protocol (IP) technology.

Today there are thousands analogue medical alarms in Australia which, in future, will be difficult to maintain their level of service due to the continual introduction of digital only networks.

The medical alarms previously on the market have traditionally been based on analog technology, which has limitations on the quantum and quality of information transferred. New developments in technology have allowed us to provide new medical alarm systems through IP technology with broadband and GSM connectivity.

For medical alarm systems, the new digital IP telecommunications technology allows more information to be processed to be used quicker and more efficiently. Medical alarm systems in the future will have a broader scope in the digital environment.

The Future is Digital!

 

A digital medical alarm can be described as a unit for transmission of voice and data over an IP network using Internet protocol TCP or UDP. This is the same type of communication normally used for the Internet, with all of the features and accessories similar to those of the traditional analogue Medical Alarm dialers. The main difference is that a device that communicates digitally signals constantly online and communicates constantly; alarms and alerts can thus rapidly be transferred to the designated recipient. This is usually done free of call costs for the individual.

IP communication also allows other information (data) to be sent in both directions such as services like voice messages, video, medical data, etc. This type of communication is very limited in the traditional analogue medical alarm dialer or phone because the analogue protocols only allow a brief DTMF handshake and then a very simple method of data transfer.  The rate of data transfer in an a analogue system is at a much slower rate compared to today’s digital systems.

The use of tradition communication methods is a very expensive way to stay in constant contact.

Analogue Medical alarm systems linked into an IP-subscription via a so-called ATA-box (analogue to digital converter or filter) is not considered a digital medical alarm.  Communication still occurs with DTMF protocol (see Analogue medical alarm) which is converted to digital communications in the ATA box. In addition to uncertainties arising in the conversion, this solution has all the analogue constraints that have been previously mentioned.

Units that communicate wirelessly via GPRS or 3G, are considered digital medical alarms because this technique also allows a constant connection to the IP network. The GPRS or 3G solutions should not be confused with the analog medical alarms that communicate via GSM as a converter.  The GSM via converter option still communicates by an analogue function and with this comes all the of analogue communication constraints.


 

 

  

The problem with traditional analogue medical alarms in a digital environment

 

In 2006 according to the Swedish Association of Local Authorities and Regions, many new buildings in the world are, in principle, only going to use IP-based communications platforms.

Traditional analogue medical alarms connected to the digital network require an ATA adapter. This does not always work satisfactorily and has created a variety of incidents with safety. Also, this never fully utilizes the digital network and all its bandwidth features.

Unfortunately DTMF (Dual-tone multi-frequency) and Internet Protocol simply do not speak the same language. Although there are adapters that can convert signals from the IP-based communications to a standard telephone jack, only adequate functionality is ever ensured.
