We used to have two customers with the synch serial interfaces like
this.  One did the serial point-to-point over leased line using DDCMP
to tie three remote sites together.  The other tied into the TELENET X.
25 service to do the same thing with 6 remote plants.  It pretty much
"Just Worked" except for the security problems that TELENET
experienced once the 'leet haxors' of the day started dialing random
numbers on it.

VAX P.S.I. software was used for the X.25 connectivity, and I think
that with VMS V6 and later you had to have the WANDD WAN Device
Drivers kit (and license???) to get things working.
