- # I have been doing some testing with version 9.0-1 of the routing
- # software and have come up with something that I can't explain.
- # I was comparing an ISDN link running DDR through a terminal adapter (Ascend)
- # and a dedicated link running through a DSU/CSU (Larse). Both are 384k
- # but the terminal adapter gives much better performance. When we put
- # an analyzer on the link we see periodic delays on the dedicated link but
- # no delays on the terminal adapter link. Both are running V.35 on a MCI
- # card and are simularly configured. Can anyone explain why these are giving
- # a large difference in performance ?
