Example 2:
To lower expenses, FCD-IPM is configured so that a line to the Internet is activated
when there is a need to connect to the Internet and terminates when no frames
are transmitted for 60 seconds. Therefore the following must be defined:
• Start Connection is any frame to forward
• Terminate Connection is no frame to forward for 60 seconds (see Figure 5-93).
ISDN
INTERNET
Any frame starts a
connection
Connection is terminated if
3 frames/60 seconds are
not forwarded

Example 3:
The company management wants to allow the PC with the IP address 1.2.3.4 only
access to the Internet. In addition, the connection to the Internet is to be
terminated if 3 frames every 60 seconds are not transmitted from this PC.
Therefore the following must be defined:
• Start connection must be specific frame to forward. A filter which allows only
frames from the 1.2.3.4 IP address must be defined.
• Terminate connection must be no specific frame to forward. A filter which
counts only frames from the 1.2.3.4 IP address must be defined. In addition
the rate must be defined at 3 frames/60 seconds (see Figure 5-94).
