RLOS and RALOS detect circuitry continues to operate and report receive signal status.
XTIP/XRING output data is unaffected.
TAIS Pin Enable—Allows the use of the TAIS hardware pin instead of the TAIS register bit to
manually transmit AIS.
LLOOP Pin Enable—Allows the use of the LLOOP hardware pin instead of the LLOOP register
bit to control loopbacks.
RLOOP Pin Enable—Allows the use of the RLOOP hardware pin instead of the RLOOP register
bit to control loopbacks.
0 = Use RLOOP register bit
1 = Use RLOOP pin
Receive Analog Loss of Signal Detect—Indicates receiver analog loss of signal.
Receive Loss of Signal Detect—Indicates receiver loss of signal.
Transmit Loss of Clock Detect—Indicates loss of transmit clock, TCLK.
Transmit Loss of Signal Detect—Indicates a transmitter signal fault detected by the DPM.
Transmit Short Circuit Detect—Indicates transmitter output overload.
Jitter Attenuator Error Detect—Indicates jitter attenuator FIFO overflow or underrun.
Bipolar Violation Detect—Indicates a bipolar violation error in the receive path. If ZCS encoding/
decoding is enabled, BPV is asserted only for bipolar violations which are not part of the ZCS
code.
0 = Use TAIS register bit
1 = Use TAIS pin
