AT Command Guide PTT Testing This facilitates testing of signal levels and provides a continuous signal when the modem is in IDLE mode. This allows the user to initiate a series of signal that are necessary for PTT approval. These signals are answer tone, carriers, modulation, and other pertinent signals. A selected test will be terminated when any keyboard character is entered. The followings are command descriptions. Note: For DTMF, the transmit level is -10dBm for low band and -8dBm for high band, inter digit delay is fixed at 70ms. All other transmit levels are adjustable according to the setting of register S91 (from -10 to -15dBm). %P00 - %P09 %P10 %P11 %P12 %P13 %P14 %P15 %P16 %P17 %P18 %P19 %P20 %P21 %P22 %P23 %P24 %P25 %P26 %P27 %P28 %P29 %P30 %P31 %P32 %P33 %P34 %P35 %P36 %P37 %P38 %P39 %P40 %P41 %P42 DTMF tone digits from 0 to 9.
