VCS 2700 voice communication system is designed to be used in air traffic management centres (ATM) in order to provide operational controller radio- and telephone communication of air traffic controllers/ planners with aircraft crews, interacting ATM services and units, departmental and airport services.
VCS 2700 provides advanced performance features such as minimal connection time, high fault tolerance, and operational availability, wide scalability, an extensive range of interfaces that provide the ability to interface with both legacy and advanced radio- and telephone-communication equipment, as well as provides the operator with a variety of basic and additional services.
Azimut's solution for the voice communication system VCS 2700 is modern, flexible, and allows efficiently expanding the system throughout its life cycle.
The following factors are of primary importance for every air navigation service provider (ANSP) worldwide: increasing air space capacity and flight safety while saving flight time, reducing aircraft downtime, and decreasing fuel costs for airlines. Azimut helps ANSP reduce operational delays by ensuring maximum operational availability, reliability, and fault tolerance of the VCS 2700.
The VCS 2700 by Azimut provides fast installation and ergonomic controller interaction, which enables efficiently implementing projects in the shortest possible time.
The VCS 2700 provides reliable services for ATM units and authorities in accordance with the requirements of international standards for VoIP (ED-136, ED-137).
The VCS 2700 provides a safety-critical, reliable air-to-ground and ground-to-ground connection for standalone and networked ACCs, ACTs and air hubs. The VCS 2700 architecture ensures reliable ATM service delivery and minimizes delays and disruptions. The IP technologies used in the VCS 2700 by Azimut provide uncompromising voice quality and ATC security measures:
The VCS 2700 by Azimut is a scalable platform to perform operations from a small airport to a networked ACC.
|VCS 2700 is implemented as two independent system subnetworks - A and B, operating completely in isolation and in parallel at any given time with equal priority. There is no synchronization and no interconnection between the systems A and B.
|Parallel operation has significant advantages over hot standby systems in other systems:
✔ Should any module fail, there occurs no loss of communication because there is no switchover time;
✔ Connection failures do not affect system performance;
✔ Exceptional operational availability of the system;
✔ The VCS 2700 system enables placing redundant half-sets of the system in separate rooms or buildings. This provides additional safety in case of, for example, attacks or fire.
|All decentralised processor units also in the interface racks are fully redundant
✔ Failure of a single processor unit does not affect the operation of the system;
✔ Any failure of a single line card does not affect the rest of the system;
✔ All line cards and processor modules allow hot swapping to ensure maximum availability and easy maintenance.
|The compact touch entry device (TED) at each controller working position is the controlling element for the controller working position as well. The module serves for the voice communication system including the complete working position electronics without any moving parts such as fans or hard drives.
✔ Fast reaction time ensures no delays for the controllers’ operation;
✔ No moving parts provide a very high availability of the hardware being used (high MTBF value) and therefore there is no need to conduct periodic maintenance;
✔ Reduced spacing between controllers’ consoles since there is no need to install separate electronics for each working position;
✔ There is no risk of overheating of working position electronics inside the consoles.
|The controller working position equipment is connected via two independent E1 or LAN segments. In case the controller working position is connected via LAN, it has two independent IP addresses, which are not part of the same subnetwork, in order to reach full independence in case of single LAN outages.
✔ There is no single point of failure when using the E1 and LAN;
✔ No communication loss in case of E1 or LAN outages;
✔ The highest availability of the system, since each working position uses two independent IP addresses.
|The system supports automatic switchover from the main (primary) to the standby radio station, as well as manual switchover.
|✔ In case of a radio failure, the system can automatically switch over to the standby radios to ensure permanent air / ground communication.
|Activating new (updated) user roles at the working positions can be executed during system operation.
|✔ No need to restart the working position, which means that the ongoing communication session will not be interrupted.
