AUTOPATCH
CONVERSATION CONTROL NOTES
During a standard half-duplex autopatch, the mobile operator always has control of the
conversation. When the mobile is transmitting, audio from the receiver is fed to the phone line.
Audio from the phone line is not allowed to feed the transmitter. If autopatch privacy is turned off,
then the mobile audio is allowed to repeat. If auto patch privacy is turned on, the mobile audio is
not allowed to repeat.
When the mobile is listening, audio from the receiver is not allowed to feed the phone line. Audio
from the phone line is fed to the transmitter.
With this scheme, the mobile operator can cut off the telephone party by simply pressing the PTT
button.
During a full-duplex autopatch, audio feeds both ways for the duration of the conversation.
Operators do not have the ability to cut off the telephone party with PTT, but must control the call
with only the Dump command.
