System Notes

Cobb County serves as the system core for its own Sites, as well as sites operated by Douglas County, Forsyth County, Cherokee County, Bartow County and Polk County. Cobb County, Douglas County, Forsyth County, Cherokee County, Bartow County and Polk County talkgroups are always heard on their own respective Sites, and on other sites on an as-needed basis.

Site 2 (the legacy UASI Atlanta overlay) was decommissioned when Cobb upgraded their core in December 2017.

Polk County recently built their own simulcast site and is in the process of moving users to it.

Many talk groups use Dynamic Dual Mode, which allows the talk group to automatically switch to TDMA (Phase II) when only TDMA-capable subscriber radios are active on the talk group but revert to Phase I when older radios are active on the talk group. As a result, many talk groups below shown as "D" Mode (Phase I) may intermittently become T (TDMA, Phase II) and only be monitored on a Phase II capable scanner at any time.

System Assigned ISSI Patch Talkgroups

North Fulton Regional Radio System Authority (NFRRSA) and Cobb County Regional Radio System (CCRRS) have created an Inter RF Subsystem Interface (ISSI) link that allows users of certain NFRRSA and CCRRS talk groups to automatically roam onto the other's system in certain areas where the primary system has weak coverage but the partner system has strong coverage. A temporary talk group on the partner system is automatically assigned and linked back to the user's home talk group on the primary system. On the CCRRS system, talk groups in 40,000 range are part of a pool of talk groups that are automatically randomly assigned by the CCRRS for these temporary ISSI links to NFRRSA talk groups on an as-needed basis, with no user, dispatcher or system administrator intervention required. Some of the CCRRS talk groups that have been heard used for this purpose are listed below. This is not a complete list.
