Transmit All Ones (TAOS) can be set by setting the TAOS_n control bits to “1” in the Channel control registers.
When the TAOS is set, the Transmit Section generates and transmits a continuous AMI all “1’s” pattern on
TTIP_n and TRing_n pins. The frequency of this ones pattern is determined by TxClk_n. the TAOS data path
is shown in Figure 34. TAOS does not operate in Analog loopback or Remote loopback modes, however will
function in Digital loopback mode.
