RT7 SECURE DIGITAL VOICE
The Vocoder rate is adapted dynamically to allow optimal quality in all channels. Broadcast and Private-Lines selective call modes are supported, as well as automatic Late Entry.
USAGE MODES
Local User: The operator uses a handset connected to the RT7 front panel. The RT7 provides an Address Book to initiate Private Line calls or to send locally entered Messages or files.
Remote User: The operator is situated away from the device. Audio input is via the Intercom connector. The RT7 can then be operated via RAPTAWC CommandPoint or MessagePoint.
RT7 SECURITY
All over-the-air communications, locally stored messages and positions are encrypted. Access to the unit is restricted by means of an Access Code. A Zeroize function is provided from the keypad and CommandPoint which erases all data and keys.
| VOICE/DATA MODE RT7 MODEM | KEY MANAGEMENT & SYSTEM CONFIGURATION The Key Management Software (KMS256) includes Key Management Tools and is provided on a CD along with the necessary cable and USB Key Fill Device. The MIL System Configuration Software (SCS) includes Network Configuration, Periodic position transfer, Address Book and CALLSIGN Configuration. MIL SCS and KMS256 is part of the Configuration Bundle which includes all required manuals, cables, Fill device and software for system start-up. |
| JOINT OPERATIONS INTEROPERABILITY The RT7 interoperability with the AT RT5 for manpack or vehicleuse, providing seamless interoperability between various forces. The same Key Management System is used on both devices. | POSITION TRANSFER If configured to do so, position information is included with every Chat transmission as well as being sent periodically (configurable). |
| EMAIL: GATEWAY & COMMANDPOINT The RT7 can connect with Gateway, MessagePoint or CommandPoint Software via the Local Ethernet port to provide end-to-end Email (with attachments) and GSM SMS connectivity (via Gateway) or Situational Awareness capability. | RT7 ACCESSORIES Accessories - Included: H-250 Handset Accessories – Required one per unit: Radio Cable - Contact AT Comms AG for list of radio specific cables. Accessories - Required one per network: Configuration Bundle. Accessories - Optional: 19" Mounting Tray, Handset Clip, GPS Active Patch Antenna (TNC), Connector interface kit, FILL Device. |
