REMOTE LOOPBACK:
With Remote loopback activated as shown in Figure 28,the receive data on RTIP and RRING is looped back
after the jitter attenuator (if selected in receive or transmit path) to the transmit path using RxClk as transmit
timing. The receive data is also output via the RPOS and RNEG pins.
During the remote loopback mode, if the jitter attenuator is selected in the transmit path, the receive data after
the Clock and Data Recovery Block is looped back to the transmit path and pass through the jitter attenuator
using RxClk as the transmit timing.
NOTE: Input signals on TxClk, TPDATA and TNDATA are ignored during Remote loopback.

TRANSMIT ALL ONES (TAOS):
Transmit All Ones (TAOS) can be set either in Hardware mode by pulling the TAOS pins “High” or in Host mode
by setting the TAOS 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 and TRING pins. The frequency of
this “1’s” pattern is determined by TClk.TAOS data path is shown in Figure 29.
