Voice and data recording has become a requirement for quality control, internal audit
processes and security for most industries. The same applies to typical radio
networks, such as those used by emergency services, airports, large security
companies, police forces or protection services, fire departments and the military.
However, while recording voice interactions over radio networks is not a new concept,
the relatively new addition of Short Data Service (SDS) – a technology similar to
Short Message Service (SMS) offered by GSM operators which enables coded data
messages to be transferred between radio devices – has posed a challenge for radio
network users in terms of recording these interactions – until recently.

Jasco has enhanced their DataVoice Libra Capture platform solution for certain Tetra
networks to include the recording of SDS communications, allowing providing users of
Tetra devices with the ability to use DataVoice Libra Capture to record SDS messages
and responses.

“This expansion has been trialled with select Tetra customers for the more than a
year, now, and has met with remarkable success,’ says Danie van Antwerpen, Channel
Manager at Jasco Group, “The feature allows for users to record communications
across multiple channels on their Tetra network, something that has been limited to
voice in a radio solution.’

“For example, an electric grid may make use of Tetra networks to automatically relay
messages containing circuit information to activate or deactivate certain services at
the substation. When disputes have arisen due to faults or failures, proving that these
messages were properly relayed and received and that the correct chain of events
took place accordingly – has been difficult to accomplish. DataVoice Libra Capture’s
enhancements mean that organisations can now prove that such messages were
relayed and that they were acted on. For the organisation, this means they are
protected. Customers receive peace of mind that their service is being provided, and
organisations can also monitor internal processes and staff.’

The DataVoice Libra Capture addition also records distress signals sent and received
across a Tetra network, enabling organisations to track when these were sent, who
sent them and when or how they were responded to. Adds van Antwerpen, “For
protective services, such as a police force, it may not always be safe to relay a voice
communication, nor is there always time to tap out a message. Sending an automatic
alert is often the answer in these situations, and the Libra Capture platform is able to
record these.’

“Another unique feature of SDS recording is that the actual content is recorded and
able to be extracted, and not just the fact that the communication was sent or
received. Because these types of messages are sent in code, accessing and
extrapolating the recorded data can be tricky. With DataVoice Libra Capture, this is
done for the customer automatically.’

Van Antwerpen goes on to say that Jasco are currently working on several new
developments for this product, highlighting key future enhancements such as
geolocation recording and graphical reporting. “We are fully invested in bringing to
market a product that completely supports the functionality of Tetra devices, and will
continue to make new expansions available in line with Tetra’s own development.’
