DTMF COMMANDS
All the DTMF programming command are listed here. They are limited in scope and are intended to
be used mainly for Initial setup and adjustment, and diagnostics. The ability to turn on and off a user
via DTMF has also been included.
Access to DTMF programming is done with the full five-digit program access code, 12748 (default).
Over the air:
Keyup a DTMF equipped radio on the same frequency as the Model 748. Have the radio set for
monitor (prompt tones from the Model 748 are not tone protected). Enter the program access
code(12748 default) and unkey, the Model 748 will keyup and issue five short beeps to confirm
access.
From the Telephone:
Call up the Model 748's phone number. When prompted by the Model 748 (925 Hz beep) to overdial
a user number or ANI, enter in the program access code (12748 default).
CAUTION : you will hear
Modem tone scream in your ear! Once you get the modem tones, enter a DTMF “#”, this will stop
the Model 748 from looking for a modem. You should then hear five short beeps to confirm access
to the DTMF programming mode.
DTMF commands work very much like they do in Model 38 or Model 39. The basic format is:
“Command Number” + “#” the Model 748 will keyup and send two short beeps.
“Data” + “#” the Model 748 will keyup and send five short beeps.
Note: if programming from the phone, the Model 748 doesn't keyup.
The “#” is used as a termination digit. It lets the Model 748 know that all the digits (command or
data) have been entered, please process them.
