6.5.1. A0
Answer and transmit the AIN analog input signal on the
telephone line and connect the phone line receive
signal to the AOUT pin (see Figure 10B). This mode
also monitors for local DTMF received signals and user
defined tones. Any received character is echoed. User-
defined tones are echoed as X and Y. Transmission of
any data to the Si2400 UART will cause the modem to
go into the command mode. The modem can then send
DTMF tones via the “ATDT #!0” command (where #
represents a DTMF character 0-9, A-D, # or*) or be
disconnected with the “ATH” command. The “ATDT #!0”
command string does not initiate a new call since the
modem is already connected.
Notes:
1. DRT must be set to data mode (SE4[5:4](DRT) = 00b)
before attempting to send tones after a “A0” command.
User defined tones are enabled by setting S14[6]
(UDF) = 1b and require DSP low-level control as
defined on page 40. The online mode can be resumed
by issuing the “ATO” command. (see the “!0” section
for more detail).
2. DTMF detection is only intended for local detection
of a parallel device.
6.5.2. !0
After dialing the number, go to DTMF monitor mode with
no modem connection. After dialing the !0 mode is the
same as the A0 mode described previously.
Example: Dial a number and detect DTMF tones in
“data mode.”
Example: Dial a number and place the Si2400 in “voice
mode.”
DTMF detection is only intended for local detection of a
parallel device, not for detection of a remote source
over two local loops. “Data mode” (see example above)
DTMF detection is reliable on a quiet line without the
presence of interfering audio signals or voice. DTMF
detection, although possible, in the “voice mode” (see
example above) is not recommended and can be
unreliable.
6.5.3. !1
Dial number and follow the DTMF security protocol.
The format for this command is as follows:
ATDT<phone number>!1<message 1><CR>
K
!<message 2><CR>
