Creating the Responder Phase Swap Line Display Layer

Add the RxLineDisplay layer to the Responder_Cached group in your map.
Right-click RxLineDisplay and select Properties.
Select the Symbology tab.
Type Phase Swap in the Label appearing next to the symbol in the Table of Contents field.
Click the line symbol to modify the color and size used to display it on the map.
Select the Definition Query tab.
Enter the following in the Definition Query field: RXPHASE LIKE '%To%' (using the field that is assigned the RXPHASE model name).
On the Labels tab, select RXPHASE for the Label field.
Click OK to save changes in the Layer Properties.

NOTE: Move the Responder Phase Swap layer above the other LineDisplay symbols to appear correctly as the top-most layer of displayed lines in ArcMap.
