Claim 6

A radio comprising: a receiver and detector for receiving and detecting transmissions including a data signal and a subsequent signal having a signal type, said data signal having an information word including an information field associated with the signal type of said subsequent signal, and said signal type of said subsequent signal having a specified mute time variable for setting a mute duration for an audio output of said radio: decoding means for decoding said information field associated with said signal type of said subsequent signal; muting means for muting the audio output of the radio for said specified mute duration, from the end of the time when said data signal is received, to the end of said mute duration, when said subsequent signal is detected, in response to said specified mute time variable; and means for unmuting the audio output of the radio, after said specified mute time variable, if said subsequent signal is a voice type signal.

Claim 7

The apparatus of claim 3 wherein said muting means includes means for muting the output of the receiver for at least a first time interval in response to said information field associated with a subsequent data signal having said specified mute time variable of said first time interval.

Claim 8

The apparatus of claim 4 wherein said muting means includes means for muting the output of the receiver for a second time interval in response to said information field associated with a subsequent voice signal having said specified mute time variable of said second time interval before unmuting a speaker of the receiver.

Claim 9

The apparatus of claim 5 wherein said muting means includes means for muting the output of the receiver for a third time interval in response to said information field associated with a subsequent coded voice signal having said specified mute time variable of said third time interval before unmuting said speaker of the receiver, wherein said third time interval is greater than said second time interval.

Claim 10

The apparatus of claim 3 wherein said muting means includes means for muting the output of the receiver for at least a first time interval in response to said information field associated with a following data signal, said first time interval including the time duration between data packets and an attack time to detect the identified presence of said following data signal, to substantially avoid a data burst associated with said following data signal.

Claim 11

The apparatus of claim 7 wherein said muting means includes means for muting the output of the receiver for a second time interval in response to said information field associated with a following coded voice signal, said second time interval including the time duration between signals and an attack time to decrypt said coded voice signal to avoid hearing the decryption of said coded voice signal.

Claim 12

The apparatus of claim 3 wherein said muting means includes means for muting the output of the receiver for said specified mute time variable, said specified mute time variable including a variable attack time associated with each type of said subsequent signals.

Claim 13

The apparatus of claim 3 wherein said decoding means includes means for decoding said information field specifying a first subsequent signal having a first mute time variable, a second subsequent signal having a second mute time variable, or a third subsequent signal having a third mute time variable.

Claim 14

The apparatus of claim 3 wherein said decoding means includes means for decoding said information field specifying a selected duration for said specified mute time variable.

Claim 15

A radio for controlling a speaker mute time in a receiving radio, comprising: transmitter means for transmitting a first signal and a second signal in the same transmission; and means for generating the first signal having a digital word specifying whether the second signal is a data signal having a first attack time, an uncoded voice signal having a second attack time, or a coded voice signal having substantially no attack time, the attack time being a mute time variable needed to mute the receiving radio while the receiving radio is detecting an identified presence of the second signal and unmuting the receiving radio, after said specified attack time, if said second signal is said uncoded voice signal or said coded voice signal.

Claim 16

A radio for controlling a speaker mute time in a receiving radio, comprising: transmitter means for transmitting a first signal and a second signal in the same transmission; and means for generating the first signal having a digital word specifying whether the second signal is a data signal having a first attack time, an uncoded voice signal having a second attack time, or a coded voice signal having substantially no attack time, the attack time being a mute time variable needed to mute the receiving radio while the receiving radio is detecting an identified presence of the second signal and unmuting the receiving radio, after said specified attack time, if said second signal is said uncoded voice signal or said coded voice signal.
