AIR TRAFFIC MANAGEMENT SOLUTIONS

Harris Voice Communications System for the 21st Century (VCS21) is a global,

next-generation Voice over Internet Protocol (VoIP) communications system for

air traffic management (ATM) that meets ED-137 specifications. VCS21 facilitates

ATM modernization programs by delivering net-centric voice communications that

reduce dependency on traditional point-to-point communications.

The system replaces proprietary, time-division multiplexing (TDM) communications hardware with standards-based, net-centric VoIP-enabled nodes. This allows communication resources to scale directly with each added endpoint, eliminating the problems associated with fixed capacities in TDM-based systems.

VCS21 architecture distributes the network core to peripheral equipment. With the intelligence distributed over various elements, a failure at one part of the system does not affect operation in the rest of the system, and the IP network does not rely on a single interface connection. The use of the Parallel Redundancy Protocol (PRP) protects against network failures, ensuring continued operation of the voice network, ultimately resulting in higher system reliability and availability.

VCS21 allows net-centric and legacy voice systems to coexist. This enables a seamless transition during ATM modernization programs of virtually any size and complexity, from small, single-tower installations to national and multinational voice systems. The system also operates as a fully networked enterprise voice system, with enhanced capabilities for business continuity planning, asset sharing, and future facilities.

> Seamless integration into ATM systems

– Advanced technology with interoperability to legacy telephone and radios (2-wire, 4-wire, etc.)

– Plug and play capability to preserve existing capital investments, and to enable migration to IP platform

– Lowers transition risk and mitigates impact to ongoing operations

> High availability

– Decentralized architecture

– No single point of failure

– No performance breakpoints

– Dual active facility LAN with PRP on each component

> Security controls and protection

– IPSec, Access Control (AC) service, audit and accountability service, System and Information Integrity (SI) service

> Flexible/advanced human machine interface (HMI)– Badges embedded within buttons– Drag-and-drop style editor– Single or dual display

– Portable applications (tablets and laptops)

> Reduced system and life cycle costs

– Open architecture and standards with ED-137, ATS-R2, SNMP, IPv4, IPv6, DHCP, NTPv4, IPSec, service oriented architecture (SOA) interfaces

– Ability to seamlessly scale the system over the facility life cycle

> Optional primary/backup configuration

– Two independent systems to prevent propagation of failures

– Controller working positions accessing both systems over four LAN interfaces

– IP radio and telephone resources always connected to both systems

– Legacy resources mirrored on both systems and handled via A/B switch

– Initiating switchover from primary system, backup system, and enterprise level user (remote location)
