What are the advantages of the APPX Router when compared to a pure TCP/IP link?
A. Your host system may not have TCP/IP connectivity, making that an unavailable alternative. As a matter of fact, TCP/IP only recently became available as part of the VSE operating system. While it has been available for MVS for some time, it may not be installed on the host system you want to access. Since the Router uses LU6.2 for connectivity with the host, VTAM is required, but not TCP/IP. Using the Router also adds extra security, and offloads the TCP/IP processing from the mainframe.
