In current two-way radio systems each radio can be associated with one or many talkgroups. A subscriber unit can have many modes with one talkgroup assigned per mode. Each mode can be programmed to unmute to voice calls with matching talkgroups, any voice call or voice calls with the all talkgroup in Conventional systems, or the announce- ment talkgroup in Trunking systems. Voice calls can also be patched together by fixed network equip- ment to allow multiple talkgroups (Trunking), or multiple channels (Conventional), the ability to com- municate with each other. Radios on a trunking mode will always unmute to system-wide calls.
