Tt - Ptt Test Command - Conexant H08-15355F Reference Manual

3.2.9.2 %TT - PTT Test Command

This command facilitates PTT testing of signal levels by providing continuous signals regards of whether or not the modem is
connected to the line. The signal transmitted is in accordance with the parameter provided.
A range of commands allows the user to initiate a series of signals required to obtain PTT approval. The signals emitted
include answer tone, modulation, carriers, and other pertinent signals. A test is initiated upon receipt of a %TTn (the second T
is a password and n is a test number), and the test is aborted when any keyboard character is entered. The modem will
continuously transmit the tone or carrier according to the parameter supplied.
