About Filtering
Your Prestige uses filters to decide whether or not to allow passage of a
data packet and/or to make a call over the ISDN line. There are two
types of filters involved: incoming data filters and outgoing data filters.
Data filters screen the data to determine if the packet should be allowed
to pass.

For incoming packets, your Prestige applies data filters only. Packets
are processed depending upon whether a match is made. Your Prestige
allows you to customize the filter sets that you wish to use. The
