In cascade mode, packets from POS terminals to the FEP are processed by Router A and then by Router
B.
To Router A, Router B serves as the FEP using TCP connection mode.
•
• To router B, Router A serves as an Ethernet POS terminal device.
Router A creates a TCP connection for each POS terminal, so Router B can determine the destination POS
terminal based on the TCP connection.
To use the cascade mode:
Establish TCP connections between Router A and Router B.
