SITTI UPGRADES DHMI SMART VCS SOLUTION (TURKEY)
The Turkish ANSP (Air Navigation Service Provider), DHMI, is currently undergoing a very large project for the modernization and rationalisation of their connections between their VCSs (Voice Communication Systems) and remote radios deployed in the country.
In the past years, SITTI has been providing DHMI with TDM-based VCSs that have been installed at all main ACC and APP centres for the management of the air traffic in the Turkish crowded skies. Such VCSs are connected by means of an IP network reaching all remote devices and allowing intercom conversations between controllers at different sites. This is the so-called “SMART” network.
With the new communication paradigm defined by the EUROCAE ED-137 standard (which details the way VoIP – Voice over IP – has to be used in the ATC world), the VCSs used at the Turkish ACCs will be upgraded to a new full-standard version (MULTIFONO® M800IP®) that is natively dealing data and voice streams in full adherence to the latest international standards.
The current plan by DHMI is to install the new VoIP capable VCSs at all ACC and APP sites and to create a new full VoIP network that will be used in parallel to the existing one. The current TDM-based VCSs will also be used in parallel to the new ones. After a suitable consolidation and observation period, the previous IP network will be dismissed, while remote radios will continue having their analogue connection to the current TDM VCS.
When all transition phases will be over, DHMI will be using a full standard VoIP network connecting all VCSs and remote radio sites, thus benefitting of all the advanced provisions and features envisaged by the ED-137 standard. For contingency reasons, remote radios will still be reachable via analogue connections from the current TDM-based VCSs.
In accomplishing this very complex project, DHMI could rely on the large experience and expertise by SITTI, this latter once more demonstrating the capability of dealing and managing large networking and system integration projects involving many different devices and connection links.
