RF channel expansion in a trunked radio communications system

摘要: In a trunked radio frequency communications system, an arrangement dynamically "expands" or extends the allocation table stored within "personality" defining non-volatile storage device of transceivers to include additional RF channels. A channel configuration control message specifying logical field and FCC number is periodically transmitted over active digital channel. Transceivers correctly receiving this extend their tables add entry specified by message. The reference these records in response call messages are thus capable operating on new Channel repeated at time intervals long enough ensure have no real adverse impact loading but short cause almost immediately update information. Errors prevented from occurring transmitting both slots outbound requiring receipt non-zero site identification before processing any
