P25 Digital Mode Capabilities

Expanded Signaling

  • Supports selective calling, Talk Group IDs (TGID), Network Access Codes, Individual ID lists and Paging Group lists for flexible communications.

Secure Communications

  • Options available to support both Advanced Encryption Standard (AES) and Data Encryption Standard (DES) as required by APCO Project 25. Multiple encryption keys can be stored in the radio.

Mixed Mode

  • Seamlessly switch between analog to P25 digital mode on each channel based on call type received and on programming for transmit.

Enhanced Voice Quality
