This read-only SnmpAdminString (0-19 characters) holds the name of a tone signal class used within LMR tone configuration. Administrators use it to identify a specific named signaling tone definition among potentially many configured for an LMR interconnect. For example, an admin auditing radio signaling configuration would use this name to distinguish between multiple defined tone signals, such as those used for PTT (push-to-talk) versus other control functions.
