D0
DMO
This bit is set to “1” every time the MTIP/MRing input
pins have not detected any bipolar pulses for 128
consecutive bit periods.
0
D1
RLOS
This bit is set to “1” every time the receiver declares
an LOS condition.
0
D2
RLOL
This bit is set to “1” every time when the receiver
declares a Loss of Lock condition.
0
D3
FL
This bit is set to “1” every time the FIFO in the Jitter
Attenuator is within 2 bit of underflow/overflow condi-
tion.
0
D4
ALOS
This bit is set to “1” every time the receiver declares
Analog LOS condition.
0
D5
DLOS
This bit is set to “1” every time the receiver declares
Digital LOS condition.
0
D6
PRBSLS
This bit is set to “1” every time the PRBS detects a bit
error.
0
0x04
R/W
D0
TxLEV
Writing a “1” to this bit disables the Transmit Build-out
circuit and writing a “0” enables the Transmit Build-out
circuit.
NOTE: See section 4.03 for detailed description.
0
D1
TxClkINV
Writing a “1” to this bit configures the transmitter to
sample the data on TPData/TNData input pins on the
rising edge of TxClk.
0
D2
TAOS
Setting this bit to “1” causes a continuous stream of
marks to be sent out at the TTIP and TRing pins.
0
D3
Reserved
This Bit Location is Not Used.
D4
INSPRBS
Writing a “1” to this bit causes the PRBS generator to
insert a single-bit error onto the transmit PRBS data
stream.
NOTE:
PRBS Generator/Detector must be enabled
for this bit to have any effect.
0
D5
TxMON
When this bit is set to “1”, the driver monitor is con-
nected to its own transmit channel and monitors the
transmit driver. When a transmit failure is detected,
the DMO output will go high.
When this bit is “0”, MTIP and MRing can be con-
nected to other transmit channel for monitoring.
