Thales Operator Terminal Adapter (OTA)
The OTA is part of the Voice Communication System (VCS) used in operation sites. The Voice Communication Facilities (VCF) in the VCS are used by the operators to communicate with aircraft and naval forces afloat via Ground-Air-Ground or Ground-Maritime-Ground radio, other site operators, higher and lower echelons and other authorities and subscribers via Ground-Ground communications.
The VCS provides secure and non-secure voice communications to operators in the operation sites, between operators and external military and civilian networks and between operators and radios where that is required. The system is designed to provide a continuous 24 hours operation 7 days a week during times of peace, crisis/tension and war.
The main purpose of the OTA is to provide the capabilities required for handling all voice presented at the VCF and to perform the required red/black separation of voice and data. The OTA connects each VCF to both the secure and non-secure switching networks. The OTA is also used between the management system and the secure / non-secure switching networks so that the management system can manage both the secure and non-secure part of the VCS.
