Bear with me if this is a dumb question to the old hands, I am relatively new to both the key areas here. Can people tell me if it is possible to just plug X.25 feed(s) into one hole on a magic cisco box and get a DECNET/LAT feed out of an Ethernet hole? This may seem naiive - sorry, I just can't work out if the cicso unit is so masterfully intelligent it can put together all the packets in say, an X.25 conversation to an asysnchronous device and transform into a conversation on a DECNET port that looks like a virtual terminal LAT connection. In case anybody hadn't guessed, that is what I am wondering if I can do. I need to take terminal type conversations from an X.25 environment and make it look to a DEC Cluster of MicroVaxen like these were terminals coming at them from say a DECServer Terminal Server. Obviously I would need an X.25 card. What else? An Ethernet port to a DECNET network. OK, anything else besides brains? :-) Thanks, mail is probably more appropriate for responses - anyone wanting a possible summary should ask by mail. -- William Jackson Manager, Network Services, Gaines Hall #113 Oregon Health Sciences University (OHSU), 840 SW Gaines Road, Portland,OR 97201 (503) 494 4535 Internet: bj@ohsu.edu AT&T Mail: attmail!ohsu3b2!bj

I think it is appropriate here and others may be interested. CISCO sells a PROTOCOL TRANSLATOR (CPT) which acts like a virutal terminal server supporting LAT,TCP/IP,X.25 and probably more. It can act as a terminal server (connect to the box's address) as well a provide translation between all the protocols. DECNET (CTERM protocol) is not supported, but LAT is. <<THIS BOX WORKS GREAT>> We're using it to access TCP/IP and LAT hosts from X.25, IP hosts from LAT, LAT hosts from IP... works like a champ. Sure beats taking a terminal server and a PAD and tying them togeather! Getting it to work with shared LAT printers took a little work since and officially it isn't supported. If anyone wants info on how to do this let me know.
