C.1 5500 Express IP Control Unit
The 5500 Express IP Control Unit allows you to connect Network Stations or
personal computers equipped with an IBM Express Twinax Adapter to a
remote AS/400 system. The unit establishes these connections using TCP/IP.
The 5500 manages traffic between clients and the AS/400 system.
Although the clients physically connect to the twinax cable, these connections
appear to as a LAN connection to the client IP applications.
