REQEN
Setting this bit to “1” enables the Receive Equalizer .
NOTE: See section 2.01 for detailed description.
0
D1
RxMON
Writing a “1” to this bit configures the Receiver into
monitoring mode. In this mode, the Receiver can
monitor a signal at the RTIP/RRing pins that be atten-
uated up to 20dB flat loss.
0
D2
LOSMUT
Writing a “1” to this bit causes the RPOS/RNEG out-
puts to be grounded while the LOS condition is
declared.
NOTE: If this bit has ben set, it will remain set evan
after LOS condition is cleared.
0
D3
RxClkINV
Writing a “1” to this bit configures the Receiver to out-
put RPOS/RNEG data on the falling edge of RxClk.
0
D4
ALOSDIS
Writing a “1” to this bit disables the ALOS detector.
0
D5
DLOSDIS
Writing a “1” to this bit disables the DLOS detector.

R/W
D0
SR/DR
Writing a “1” to this bit configures the Receiver and
Transmitter into Single-Rail (NRZ) mode.
0
D1
STS-1/DS3
Writing a “1” to this bit configures the channel 0 into
STS-1 mode.
NOTE: This bit field is ignored if the chip is configured
to operate in E3 mode.
0
D2
E3
Writing a “1” to this bit configures the chip in E3
mode.
0
D3
LLB
Writing a “1” to this bit configures the chip in Local
Loopback mode.
0
D4
RLB
Writing a “1” to this bit configures the chip in Remote
Loopback mode.
0
D5
PRBSEN
Writing a “1” to this bit enables the PRBS generator/
detector.PRBS generator generate and detect either
215-1 (DS3 or STS-1) or 223-1 (for E3).
The pattern generated and detected are unframed
pattern.
