Sub-audible signaling (CTCSS/CDCSS) is used to allow a group of radios to be 

selectively called in an analog system. Programming the receive code guard equal to 

zero turns off this feature while receiving, and allows for Carrier Squelch operation, 

where the radio will unmute whenever a carrier is detected regardless of the 

transmitted Code Guard.

Network Access Codes (NACs) provide the digital equivalent of analog sub-audible 

signaling (CTCSS/CDCSS), allowing a group of radios to be selectively called within 

a system.
Users in the same area (using the same NAC) can be further divided into Talk 

Groups, with each group having its own Talk Group ID (TGID). Group Calls are made 

by designating both the users’ NAC and TGID.
Each radio also has an individual P25 unit ID. A Unit-to-Unit call contains the 

addressee’s NAC, and uses the addressee’s P25 unit ID instead of the TGID.
