E3/DS3/STS-1 LINE INTERFACE UNIT
REV. 1.0.2
Presented in Figure 33, if LIU # 1 (U1) fails, then LIU # 2 (U2) drives its DMO output pin “High”. Likewise, if LIU
# 2 (U2) fails, then LIU # 1 (U1) drives its DMO output pin “High”.
The scheme presented in Figure 33 is a better design approach. It overcomes situations in which a LIU
monitoring its own signal (Figure 32) may experience a failure mode such that it cannot drive a bipolar signal
onto the line. That same failure mode may prevent the LIU from driving the DMO output pin “High”.

The TAOS (Transmit All OneS) Feature
The XRT73LC00A can transmit an all “1’s” pattern onto the line by toggling a single input pin or by setting a
single bit-field in one of the Command Registers to “1”.
NOTE: When this feature is activated, the Transmit Section of the XRT73LC00A overwrites the Terminal Equipment data
with this all “1’s” pattern.
This feature can be activated by either of the following methods.
