AAO: The Automatic All-Ones (AAO) bit in the
Mask Register (Channel 1, bit 1) causes an un-
framed all-ones pattern to be output at the RPOS
and RNEG (or RDATA) pins when the receiver is
in a loss of signal (LOS) condition.
9.1.3
The Control A registers are read-write registers and
are shown in Table 7. The Control A registers se-
lect device configuration and power down control.
CLKE: Establishes the edge of the of RCLK that
RPOS and RNEG (or RDATA) are valid.
PD: Controls per channel power down.
ATTEN0 and ATTEN1: Controls the jitter attenu-
ator location and -3 dB knee frequency (See Jitter
Attenuator section).

CODER: Controls the coder mode function. The
TPOS, TNEG, RPOS, and RNEG pins are active
when the transparent mode is enabled. The TDA-
TA, RDATA, AIS, and BPV pins are active when
the coder mode is enabled.
AMI-T: Controls the line encoder in the transmit
direction. The selection of B8ZS or HDB3 is deter-
mined by the CON[3:0] bits (See the Transmitter
section).
AMI-R: Controls the line decoder in the receive di-
rection. The selection of B8ZS or HDB3 is deter-
mined by the CON[3:0] bits (See the Transmitter
section).
EXZ: Controls the automatic detection of excessive
zeros on the BPV pin according to ANSI T1.231
when coder mode is enabled (CODERx = 1).
