Does Cisco make a gateway that operates at level 7? If so, can anyone tell me what model(s)? Thanks. Howard Stateman Systems Support Engineer Intelligent Networks Operation, Palo Alto howeird@hpspdra.spd.HP.COM

Of course, it's not too transparent, since your users have to login via telnet and then log thru via rlogin or LAT. But I would say that that qualifies as Level 7, so the answer is "Yes. All models."

cisco makes a device that is called a Protocol Translator. It speaks X.3/X.29/X.25 and Rlogin,Telnet/TCP/IP so that users can traverse from one world into the other. There are mechanisms for setting up transparent connections so that the user doesn't have to enter two sets of names. It allows devices out in the X.25 network to appear as if it were part of the TCP/IP internet and hosts on the internet to appear as if they were part of the X.25 network. The device has the ability to map incoming X.25 calls to any IP address and port and incoming Telnet/Rlogin connections into X.25 calls with arbitrary Call User Data. The next software release will also provide LAT support. While not strictly a level 7 gateway device, it does provide forwarding service above the transport layer.
