SIGNAL GENERATOR SETUP FIELDS, continued
Loop Code Toggle OVERVIEW: The Mod e f i e l d m u s t b e s e t to a
SPLT option before the Loop Code field can be
configured. Loop codes will be transmitted until
the RTAU detects a change in the signal being
received. At that time, the pattern selected before
the loop code was set will be transmitted. For
example, when sending a Loop Up code, the
RTAU will restore the original pattern after it
receives the loop code it is transmitting, indicating
that the circuit is looped up. Note that the Loop
Code bits are displayed in the Loop Code bit field
as each code is selected. This is provided as a
convenience to the operator who may not know
the name chosen for the loop code but does know
the pattern.
NONE
NONE Disables any active loop code selected for this
field. When NONE is selected, the Loop Code
field displays 16 dashes.

(toggle and input)
Enter a 16-value expression using only 1’s, 0’s,
or “-”. The bits can be entered by typing a
string of 0’s or 1’s in the bit field located to the
right of the designated entry.
User Loop Down Enter a 16-value expression using only 1’s, 0’s,
or “-”. The bits can be entered by typing a
string of 0’s or 1’s in the bit field located to the
right of the designated entry.
*Note: “NI” means Network Interface device.
