Telephone Interface Functions
7-19
Enable/Disable Repeater-to-Phone DTMF Mute
Allows—or disallows—DTMF digits feeding the phone line from the
repeater.
This command does not affect the dialing of telephone numbers, since this
feature is in effect after the dialing is finished. The purpose of the command is
to prevent troublemakers from dialing a second phone number after a called
party hangs up. (Some exchanges return a “second dial tone” under those
conditions.)
•
DTMF digits are detected and muted from the phone line when this feature
is ON (enabled).
•
This feature would have to be turned OFF (disabled), however, when a
mobile station wishes to call a number and remotely control a device via
DTMF digits.
•
Enter one digit, 0 for OFF (disabled), 1 for ON (enabled).
