Compliance Test Commands
The following are compliance test commands:
ATS07=4ODT;
ATSE8=05\r
ATSE5=xx\r
Writes to the ATSE5 register has the following effect when in DSP
Mode 5
bit 0 : transmit_ena set to 1 turns the transmitter on.
bit 2 : QAM/nDPSK
bit 3 : orig/nans selects between originate mode and answer mode.
bit 4 : When set, enables 550 Hz guard tone
bit 5 : When set, enables 1800 Hz guard tone
ATSE6=00
ATSE6=FF
If 0, DPSK algorithm is chosen
If 1, QAM algorithm is chosen
If 0, answer mode
If 1, originate mode
// go off hook
// place DSP in mode 5 (for QAM and DPSK)
// see notes below for setting xx
// sending unscrambled zeros
// sending scarmbled ones
