Each IBM mainframe must have TCP/IP installed for this to work. OpenConnect Systems ... an IP level router ... called OCIR, encapsulates TCP/IP or UDP/IP in an LU 6.2 frame ... OCIR also can emulate IBM's SNALINK, so it can connect via IBM's TCP/IP. Date: Tue, 26 Feb 91 17:56:51 EST From: rlg@ida.org (Randy garrett) I also found a company called Brixton that has a card for the Sun that translates IP into something understandable to a 3745... There are several implementations, using disparate schemes, but no standards. The schemes about which there's any detail use either LU0 or LU6.2 transports, as expected. But unless one explicitly emulates another, there's no guarantee that their encapsulation methods will interoperate, even if they picked the same LU transport. Caveat Emptor!
