This compression is
not just available in
Cisco routers. In fact, most any router will support this
type of compression,
albeit that they may require an
expansion card.
It is also available for
Linux on
ISDN connections. The
source code is in the isdn4linux
CVS tree (www.isdn4linux.de).
Not all
ISPs support this
technology, but the speed
increase is very
noticeable. Expect anything in between 15 to 75
kb/
s on just one ISDN channel (64
kilobit) for un
compressed data (
text or
html for
example).
