INVQRSS_n
Invert QRSS Pattern:
When TQRSS is active, Writing a “1” to
this bit inverts the polarity of transmitted QRSS pattern. Writing
a “0” sends the QRSS pattern with no inversion.

TXTEST2_n
Transmit Test Pattern bit 2
: This bit together with TXTEST1
and TXTEST0 are used to generate and transmit test patterns
according to the following table:
TDQRSS (Transmit/Detect Quasi-Random Signal):
This
condition when activated enables Quasi-Random Signal
Source generation and detection for the selected channel
number n. In a T1 system QRSS pattern is a 2
20
-1 pseudo-
random bit sequence (PRBS) with no more than 14 consecu-
tive zeros. In a E1 system, QRSS is a 2
15
-1 PRBS pattern.
TAOS (Transmit All Ones):
Activating this condition enables
the transmission of an All Ones Pattern from the selected
channel number n.
TLUC (Transmit Network Loop-Up Code):
Activating this
condition enables the Network Loop-Up Code of “00001” to be
transmitted to the line for the selected channel number n.
When Network Loop-Up code is being transmitted, the
XRT83L34 will ignore the Automatic Loop-Code detection and
Remote Loop-Back activation (NLCDE1 =“1”, NLCDE0 =“1”, if
activated) in order to avoid activating Remote Digital Loop-
Back automatically when the remote terminal responds to the
Loop-Back request.
TLDC (Transmit Network Loop-Down Code):
Activating this
condition enables the network Loop-Down Code of “001” to be
transmitted to the line for the selected channel number n.
