"Used near the borders" refers to the "Splinter" settings that are used in areas like San Diego, CA, where the "standard" 800 MHz bandplan would conflict with frequencies used in Mexico. To resolve that conflict, a "Splinter system" will have some/many/all of its frequencies offset by 12.5kHz from the "standard" 800 MHz frequencies.
If your "do I make the table change..." question above is referring to how to enter a "rebanded" 800 MHz bandplan into Win96... you could download the most recent version of that program from
http://www.starrsoft.com and, after clicking the "Extended Tables" button on the bank you wish to edit, click on the "800 MHz Rebanded" radio button in the dialog box that appears. That will populate the table with data appropriate for a "rebanded" 800 MHz system.
