I would like to interject that European X.21 networks are an order of
magnitude more reliable than European X.25 networks, and have actually
progressed beyond X.25 in relative reliability as the X.25 networks
were upgraded.  X.21 folks in Germany and Scandinavia are waging a
"war" against the X.25 folks, inside the Telcos, to provide 99.99%
reliability when the X.25 want to provide 99.9% reliability.  X.25 in
Norway (Oslo, in particular) has a 97.95% reliability, and is a royal
pain in the butt to use for week-long connections.  (Yes, we have
those, and have _never_ experienced a clear on the X.21 network!)
I don't have exact numbers for the X.21 network as seen in Oslo, but
our experience indicates between 99.95% and 99.97%, counting an
occational call cleared immediately after connection by the service
provider.
