DTMF Repeat
When the repeater panel is active in a Model 748, it passes all audio through its repeat path while it
is decoding an enabled tone/code. It is also monitoring DTMF as it receives it, looking for a valid
Access ANI or program access code. Once the first digit of an ANI is received, the audio is normally
muted to prevent an ANI from being repeated on the channel. The
DTMF repeat command controls
this operation on a per tone/code basis. When “Disabled”, it operates as described above, muting the
repeat audio while a possible ANI is being received. When “Enabled” it allows all DTMF to be
repeated while the repeater panel has control. Once a valid ANI has been received the interconnect
takes control and the repeat audio is muted.
How to program it:
Access the Model 748 through your direct connect PC or terminal, or remotely from your PC
connected to a modem via the Model 748's internal modem. Once connected to the Model 748 and
the Main Menu is on the screen, type “2” and press
ENTER , and the Repeater Panel Menu will be
displayed. Type “2” and press ENTER , the User Menu will be displayed using the currently selected
user's data. Select the User number you wish to program (see “User Range” later in this section).
Select the item number for
DTMF repeat and press
ENTER
.
The currently selected mode or state will be shown along with a message instructing you to press the
space bar to change the mode or state, and to press
ENTER to accept the current mode or state. Each
time the space bar is pressed, the mode or state changes. Once the mode or state you desire is
displayed, press
ENTER
to accept. Note that if you accidentally pass the mode or state you want,
keep pressing the space bar and the Model 748 will wrap around (when the last choice is displayed,
it will return to the first one).
All users default to “Disabled” for DTMF repeat , muting the audio while an ANI is being received.
DTMF repeat is supported by block or range programming. See “User Range” later in this section
for details.
