VAR 3

Digital Recorder and Override

Digital Recorder and Override Controller

The VAR3 is a computer based multi-channel digital playback and controller system used to control multiple AM/FM MARK-IIID Digital Channelizer Radio Rebroadcast Systems and playback public safety & service messages by overriding (��break-in��) the normal off-air radio stations being rebroadcast in highway and mass transit tunnels.

Features

  • Independent or simultaneous playbacks of the same audio file.
  • Audio quality: FM broadcast hi-fidelity (20 to 15.000 Hz typical).
  • Audio streaming via TCP/IP allows audio distribution to multiple remote and/or local tunnel sites over layer 2 network links.
  • Microphone feed-through and ��line-level�� inputs from multiple remote sites for live broadcast capability.
  • Local and remote speaker monitor capabilities.
  • Locally and/or Remote Controlled using standard networking Internet Protocol TCP/IP. Can accept multiple client connections.
  • Scheduling Agent to setup & edit play lists for pre-programmed automatic voice break-in.
  • Supports Microphone recording and text-to-speech (TTS) message creation.
  • Hardware Management System monitor the status of radio equipment elements.
  • Control for optional In-Tunnel Broadcast Monitoring System (IBMS)
  • Discrete-Logic interfaces via Network Input/Output (NIO) adapters

NMS Servers Architecture

Single Server:

Single server running server applications. In case of failure the system will be unavailable until the computer is repaired or replaced.

High Availability Cluster:

Two or more servers are deployed in an active/standby architecture, providing continued service when failure occurs.

Web browser interface

Hyperlink to control, configure and monitor the operational parameters of each RF device to access the web interface. Typical operational parameters are frequency configuration, gain, amplifiers control, alarm threshold, settings files, log files, general and RF meters.


User level-controlled access is also implemented on each Radio device for guest, operator, technician and administrator levels.
