DTMF Dual Tone Multi-Frequency
Dual Tone Multi-Frequency (DTMF) Tone-based signaling scheme which combines two of a set of standard
frequencies. The result is a third or beat frequency (signal) which is the desired or usable signal. DTMF signaling is used as
tone-dialing in the common telephone.
Dynamic Group Number Assignment (DGNA) DGNA is a possibility to provision talkgroups into the
radio over the Air Interface.

Encryption Secure communications systems are designed to provide coded (?encrypted?) signals between some or all
links in the system. In order to do this, each device involved in secure communications is loaded with a multi-digit
encryption variable (called a key). This key is used by an encryption algorithm built into the device to encrypt voice or data
as needed. Only devices in the system with the same algorithm and encryption key can decode the encrypted signals.
Encryption The manipulation of a packet's data in order to prevent anyone but the intended recipient from reading that
data. There are many types of data encryption, and they are the basis of network security.
