[net.wanted] Need info on IBM 327x terminals and Cluster Controllers

tracy@ihuxl.UUCP (Kim) (08/08/85)

I am trying to figure out what the actual data rate is to an
IBM 327x terminal in the best of situations. That is, when an
327x is attached to a cluster controller attached to a channel.
I have gotten conflicting reports: some say that the terminal
itself can run at the channel speed, others say that the maximum
data rate to the terminal from the cluster controller is 56Kb/s.
What is the actual situation here?

I would also like to know some performance data on what the data
rate "really" turns out to be when the cluster controller is 
shared by an average number of users. Performance at a large
corporate sites would do nicely, if anyone keeps track of this
sort of thing, which I bet someone does.
