%P - PTT Testing Utilities
This facility testing of signal levels 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's description.
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 level is adjustable according to the setting of register S91 (from -10 to -
15dBm). Speaker control initiates by command ATLn.
