Hi, I am trying to determine a solution for a customer wishing to move off his VAX hardware to an emulator. He currently has x.25 access using a dpv11 on the q-bus. He wont have a q-bus on the emulator so what ethernet device can replace it? He is running VAXVMS V7.2 with DECnet IV. Possibly a DECNIS ??? Are there any others and what Layered Prod is needed for each device ? Thanks, John.
If you are looking at charon-vax then it includes emulation of serial lines and these can be mapped to a multi-port pci card. You can then use an opengear box of some sort (SD4002?) to get to ethernet.
If you upgrade (VMS) and install DECnet-Plus you could use LLC2 (over ethernet) and have some cisco box do the physical connection to the X.25 network.
John, This begs the question, what are they using X.25 for, and who, or what are they talking to? I don't imagine the X.25 phone book is very thick these days. Maybe time to upgrade their comms?
Hi all, Thanks for the replies so far. I believe the DECNIS should be the way to go. They are still available if you look hard enough. The customer says that they expect that they will use x25 for a few more years yet.
I will keep this discussion open for a while yet in case there are more replies then I will assign points. Best regards, JohnW.
Hi Volker, I believe that PSI or PSI-access s/w is needed and this can be run with DECnet Phase IV. I'm still searching for a VAX PSI SPD. So far I have had no luck. I think I have some VAX Layered Products CD's somewhere around. I have checked in a 1995 set but it must have been prior to this. Thanks.
