in voice-port configuration mode. To return to the default, use the no form of this command.

Command History

Usage Guidelines The timeout ptt command is available on an ear and mouth (E&M) analog or digital voice port only if

the signal type for that port is Land Mobile Radio (LMR). The purpose of this command is to limit

extended radio transmission. When the time limit configured with this command expires, the radio

transmitter unkeys, so that listeners on the channel cannot hear the speaker, even if the speaker continues

to talk. When the speaker unkeys the radio, the timer is reactivated.

Examples The following example specifies a maximum time of 10 minutes for transmitting a voice packet:

voice-port 1/0/0

timeout ptt xmt 10

rcv Applies the specified time limit to the reception of voice packets.

xmt Applies the specified time limit to the transmission of voice packets.

minutes Maximum time, in minutes, allowed for transmitting or receiving a voice

packet. Range is integers from 1 to 30.
