2.2. Voice Mode Example
Perform the following steps:
1. Connect hardware as shown in Figure 8 on page 9. Note that the Si3000 Evaluation Board requires an external 12 V supply
and derives 5 V power from the Si24xx-EVB. The Si24xx-EVB should be connected to the supplied power adapter or
powered through USB.
2. Enter the following AT commands to initialize the modem:
ATZ
ATE0
AT:U0071,11
AT*Y254:W0059,7785
AT*Y254:W004B,011C
AT*Y254:W004B,0545
AT*Y254:W004B,065D
reset modem
disable echo
enable voice routing firmware
enable Si3000 Hardware Interface
In actual application, this line
must be implemented as a read-modify-
write consisting of the following:
n = AT*Y254:Q0059
n |= 1
AT*Y254:W0059,n
Si3000 Reg 01 = 1C
This applies power to SPKRx,HDST,LINEO
Si3000 Reg 05 = 45
Enable HDST into ADC mixer
MIC input disabled
LINEI input disabled
Si3000 Reg 06 = 6D
Activate HDST as output
Keep LINEO muted
0 db Receive Gain Setting
AT*Y254:W004B,075C
Si3000 Reg 07 = 5C
0 dB Transmit Gain
Keep SPKRx muted
3. Type " ATDTnnn ", where nnn represents the telephone number of the remote telephone.
4. The remote phone rings and should be picked up.
5. Also pick up the local phone connected to the Si3000 Evaluation Board.
6. At this point, a voice connection exists between the two telephones.
7. It is also possible to send a series of single digit DTMF tones to the remote phone using the "AT.N" command (dot character
is in-between "AT" and "N", where N is a DTMF digit 0-9,A-F).
Example:
AT.1 sends DTMF digit 1, return to voice mode.
