User Report: Audemat Sticks the Remote for STIC
PARIS — I
can understand why signal monitoring and network supervision is a
useful tool for any broadcaster or broadcast service provider.
However, for us, the information transmitted is of such vital,
sometimes life-saving, importance that the ability to have reliable
round-the-clock monitoring and alarm management is absolutely

STIC, a Paris-based system integrator specializing in the provision
of services and networks relating to 107.7 FM — the highway traffic
information radio service broadcast on a single frequency throughout
France. We operate an extensive network with transmitters installed
on average every 7–10 kilometers (4–6 miles) along a
5,000-kilometer (3,000+-mile) stretch of highway.
We provide our
broadcast customers with turnkey solutions — everything from the
transmitter itself to the buildings where they are installed and
through to the tower and antennas.
Our latest project
involved installing a 107.7 FM network along the A63, a recently
opened 120-kilometer (75-mile) stretch of highway linking Bordeaux
and Bayonne. This required the installation of a single-frequency
network encompassing a network head-end and 10 synchronous
transmitter sites — all of which would require close supervision.
provided by the 107.7 FM broadcast is of strategic importance and we
are required to provide 99.99 percent service availability. Therefore
the selection of suppliers is of critical importance to us to ensure
that we can meet this requirement.
For the A63 project,
Audemat made us a proposal incorporating both a hardware-monitoring
platform — the FM Monitoring Silver and a software server package
called the Broadcast Manager — which could aggregate the
information from each transmitter location and provide us with a
global overview of the network.
consideration and research we selected this Audemat solution as the
most appropriate for the A63 installation and the only one on the
market that provided all the functionality we required. We went live
in February 2013.
We have an FM
Monitoring Silver platform at each of the 10 transmitter sites and
these are all linked via an IP connection to the Broadcast Manager
package running at our network operations center. The FM Monitoring
Silver units continually monitor the performance of the network and
broadcast and can stream or record the audio as required.
The units also feed
other information to let us know what is happening at the site. For
example, using the contact closures, we are able to monitor the door
contact at any given site and be alerted to the presence of any
We have found the
system easy to use and have programmed it with our predetermined
levels of acceptable performance. If any monitored parameter exceeds
the acceptable limits, an alarm will be triggered.
The alarm is not
only shown on the Broadcast Manager display but we have been able to
configure the system so that all relevant, available personnel are
notified immediately via SMS or email of the alarm condition and a
repair or maintenance team can be sent to the site to rectify the
issue as soon as possible, minimizing or avoiding any disruption to
installation in February, the Audemat system has proven reliable, and
we are pleased with the features it offers and how easy it is to
operate. With such an extensive network, we appreciate the ability to
have a centralized overview of multiple sites and to still be able to
drill down to view an individual parameter at a particular location.
This ability combined with the targeted and scheduled alarm
management capabilities allows us to operate efficiently and maximize
the use of our resources while still enabling a lightning-fast
response to problems.
An added benefit was
that we were able to order transmitter amplifiers from Audemat’s
partner company within the WorldCast Systems group, Ecreso, which
meant that we had an integrated and compatible system.
The equipment is
installed in largely un-airconditioned spaces but we have had
absolutely no problems since day one with 24/7 operation.
