First Claim
1. A method of operation for a land mobile radio system which has a cell that includes a plurality of repeaters and wherein radios in the cell transmit and receive both data and audio, the method comprising the steps of:
- determining the number of said repeaters which are free,when it is determined that more than a predetermined number of said repeaters are free, setting all of said repeaters to repeat audio and to transmit and receive data, andwhen it is determined that only said predetermined number of said repeaters are free, setting all of said repeaters except the ones of said repeaters in said predetermined number to repeat audio and to transmit and receive data and setting said the ones of said repeaters in said predetermined number to only transmit and receive data.

Abstract
A land mobile radio communication system has a plurality of cell cites, each of which includes a plurality of repeaters. The mobil radios in the cell transmit and receive both data and audio. The date component of the signal is carred as low-frequency subaudible information. In operation the system determines the number of repeaters that are available. When the system has determined that more than a predetermined number of the repeaters are available, all of the repeaters are set to repeat audio and to transmit and to receive data. However, when the system determines that only the predetermined number of repeaters are available, all of the repeaters, except for the ones of the repeaters in the predetermined number, are set to repeat audio and to transmit and receive data. The ones of the repeaters in the predetermined number are set to only transmit and receive data.
