I though there were some 230KB/sec trunks in the network for particular
high volume links (maybe that was 316 or Pluribus IMPS?).

I know from experience that running an HDH port at 316KB/sec (pgm error)
confuses the hell out of the IMP's port. I've heard that C30s have
an effective maximum throughput in the range of 250-300KB/sec.

What about C300 or other new technology IMPs? If 1822 is going to be
replaced by X.25, service much greater than 56KB/sec will be needed
by some sites. We'd love to see IMPs with T1 rate interface capacity.
