Does the 117G, ANDVT support OTAR?

The 117G, ANDVT (Advanced Narrowband Digital Voice Terminal), does not support Over-the-Air Rekeying (OTAR) functionality. OTAR is a feature that allows for secure key distribution and rekeying of communication equipment without requiring a physical connection or manual intervention. While many secure communication devices incorporate OTAR for efficient key management, the 117G, ANDVT specifically does not include this capability in its design.

This lack of OTAR support can be significant in environments where secure communications depend on regularly updated encryption keys to maintain security and prevent unauthorized access. Other communication systems may provide OTAR to enhance operational flexibility and security, but the 117G, ANDVT remains limited in this aspect.

The other options suggest varying levels of support for OTAR, such as being partially available for data or voice communications. However, the definitive absence of OTAR in the 117G, ANDVT makes the assertion that it supports OTAR outright incorrect.
