determining, before the first radio powers off, for the first radio to act as a master radio for a third radio based on determining that the first radio did not receive the qualifying transmission from the second radio, wherein the first radio and the third radio are configured to communicate with each other using time-division multiplexing.

10. The method for configuring the first radio to perform one or more master functions in the multivoice system using time-division multiplexing as recited in claim 9 , the method further comprising providing data to the third radio for synchronizing radios in the multivoice system.

11. The method for configuring the first radio to perform one or more master functions in the multivoice system using time-division multiplexing as recited in claim 9 , the method further comprising:

receiving a request from a fourth radio for an assignment to a transmission slot;

assigning the fourth radio to a first transmission slot.

12. The method for configuring the first radio to perform one or more master functions in the multivoice system using time-division multiplexing as recited in claim 9 , wherein the method further comprises determining whether or not the first radio is in a mode for the first radio to not transmit audio communication.

13. The method for configuring the first radio to perform one or more master functions in the multivoice system using time-division multiplexing as recited in claim 9 , the method further comprising:

identifying that the first radio has a parameter indicating the first radio has a preference to be a master; and

determining to act as the master radio for the third radio is based, at least partially, on:

determining that the second radio is not found; and

the first radio has the parameter indicating the first radio has the preference to be the master.

14. The method for configuring the first radio to perform one or more master functions in the multivoice system using time-division multiplexing as recited in claim 9 , wherein determining that the second radio is not found is, at least partially, determined by receiving a transmission from the second radio having a signal strength not exceeding a predetermined threshold value.

15. A first radio having instructions stored in memory, that when executed, have the first radio perform the following steps:

receive a slot assignment from a second radio, wherein the first radio is configured to act as a slave to the second radio, wherein:

the second radio provides commands for radios communicating using a multiple access protocol; and

the first radio is configured to receive and implement commands received from the second radio;

determine, after receiving the slot assignment from the second radio, that the first radio did not receive a qualifying transmission from the second radio; and

determine, before the first radio powers off, for the first radio to act as a master radio for and a third radio and a fourth radio, based on determining that the first radio did not receive the qualifying transmission from the second radio, wherein the first radio, the third radio, and the third fourth radio are configured to communicate directly with each other using the multiple access protocol, without a base station.
