Input for Channel 1 to 8
TPOS[1:8]:
When the DS26303 is configured in dual-rail mode, the
data input to TPOSn is output as a positive pulse on the line (TIP
and RING).
TDATA[1:8]:
When the device is configured in single-rail mode,
NRZ data is input to TDATAn. The data is encoded HDB3/B8ZS or
AMI before being output to the line.

Transmit Negative Data for Channel 1 to 8.
When the DS26303
is configured in dual-rail mode, the data input to TNEGn is output
as a negative mark on the line as follows:
TPOSn TNEGn Output Pulse
0 0 Space
0 1 Negative Mark
1 0 Positive Mark
1 1 Space
When TNEGn is pulled High for more than 16 consecutive TCLK
clock cycles, single-rail I/O is selected.

Transmit Clock for Channel 1 to 8.
The transmit clock must be
1.544MHz for T1 or 2.048MHz for E1 mode. TCLKn is the clock
used to sample the data TPOS/TNEG or TDAT on the falling edge.
The expected TCLK can be inverted.
If TCLKn is high for 16 or more MCLKs, then transmit all-ones
(TAO) signals to the line side of the corresponding transmit
channel. When TCLKn starts clocking again, normal operation will
begin again for the corresponding transmit channel.
If TCLKn is low for 64 or more MCLKs, the corresponding transmit
channel on the line side powers down and must be put into high
impedance. When TCLKn starts clocking again the corresponding
transmit channel powers up and comes out of high impedance.

RPOS[1:8]:
In dual-rail mode, the NRZ data output indicates a
positive pulse on RTIP/RRING. If a given receiver is in power-
down mode, the associated RPOS pin is high impedance.
RDATA[1:8]
: In single-rail mode, NRZ data is output to the pin.
Note: During an RLOS condition, the RPOS/RDATA outputs
remain active.

In dual-rail mode, the NRZ data output indicates a

CV[1:8]:
In single-rail mode, bipolar violation, code violation, and
excessive zeros are reported by driving CVn high for one clock
