Transmit Line Interface Selection: The transmit line interface is selected
according to the following table:
TnLINT1
Transmit Data Invert Enable for NRZ Data: A 1 inverts the transmit NRZ
data stream when the NRZ interface is selected. A 0 enables normal oper-
ation.
Transmit Line Rate Selection: A 1 selects the E1 line rate for channel n.
A 0 selects the DS1 line rate.
Transmit Clock Invert Enable: Valid for all interfaces. When this control
bit is set to 0, data and any other line signals, shall be clocked in on nega-
tive transitions of the clock. When set to 1, the line signals are clocked in
on positive transitions of the clock.
Transmit B8ZS Line Code Enable: When the transmit line is configured
for rail operation, a 1 selects the B8ZS line code for T1 line interfaces. A 0
selects the AMI code. For E1 interfaces this bit must be set to 1 for the
HDB3 line code. When set to 0, the AMI code is selected.
Sent Transmit Line AIS: A 1 forces either a DS1 or E1 line AIS signal to
be transmitted for the VT/TU selected in the add direction independent of
the add side alarms.
Transmit Line AIS Enable: Enables a DS1 or E1 line AIS to be sent for
the following conditions:
- When control bit TnAISE is a 1
- When control bit TnAISE is a 0
Note: When control bit TnAISE is a 0 and the Transmit Loss of Clock (TnLOC)
alarm occurs, transmit line AIS may be generated regardless of the state of control
bit TnSAIS
- Transmit Loss Of Clock alarm (TnLOC)
- Transmit Loss Of Signal alarm (TnLOS) when the rail interface is selected
- External Loss Of Signal alarm (TnLOS) when NRZ interface is selected and
- Control bit TnSAIS is a 1

NRZ Interface. The negative rail lead may be used
to input an external loss of signal indication or
external coding violations.
Rail Interface. B8ZS or AMI line code for the DS1
line rate. HDB3 or AMI line code for the E1 line
rate.
VT/TU Interface. The TnSEL1 and TnSEL0 control
bits cannot be set to 11 (dual unidirectional ring
mode).
