PEP with TCP header compression works for us for interactive traffic, with
the familiar TB+ hiccups.  With PEP we get a little better than 1KByte/sec
for bulk data transfers.  It is hard to get TB2500's out here, .25 miles
from Telebit, so I have not measured SLIP over TB-V32.  However, with
Cypress (very similar to SLIP) over a 9600 FDX private line we get about
0.5KB/sec for bulk data.

(You say bulk data at 1KByte/sec is an oxymoron?  Well, it's all relative.)
