It depends.  On RSTS there are some line characteristics that don't belong there (left over from the old days when circuit didn't exist yet) but also one or two that do.  In particular, DDCMP lines have a "receive buffers" parameter that lets you tune how many buffers are given to that device.  That's one of the few parameters that matters.  Oh yes, "verification" which should be a circuit parameter is a line parameter instead, I'm not sure why.
